Basic skills


Players can move the ball by throwing it to a teammate or swimming with the ball in front of them. Players are not permitted to push the ball underwater in order to keep it from an opponent, or push or hold an opposing player unless that player is holding the ball. Water polo is an intensely aggressive sport, so fouls are very common and result in a free throw during which the player cannot shoot at the goal unless beyond the "5 meter" line. If a foul is called outside the 5 meter line, the player is either able to shoot, pass or continue swimming with the ball. Water polo players need remarkable stamina because of the considerable amount of holding and pushing that occurs during the game, some allowed, some unseen or ignored by the referees (usually underwater). There are two types of fouls: one (like the scenario above) only results in the "fouler" giving up the ball and backing off; the other results in an ejection or kick out. Ejections are usually given if someone is being a little too aggressive; i.e. drowning or smacking someone. A player can only have 3 ejections before being majored and can not play for the rest of the game. If a player gets a brutality he or she is also not able to finish the game. An example of a brutality would be excessively cruising or intentionally punching someone. Water polo is a physically demanding activity; action is continuous, and players commonly swim 3 kilometers or more during four periods of play.[7]
Water polo is a game requiring excellent hand-eye coordination. The ability to handle and pass the ball flawlessly separates the good teams from the great teams. A pass thrown to a field position player is preferably a "dry pass" (meaning the ball does not touch the water) and allows for optimal speed when passing from player to player with fluid motion between catching and throwing. A "wet pass" is a deliberate pass into the water, just out of reach of the offensive player nearest the goal (the "hole set") and his defender. The hole-set can then lunge towards the ball and out of the water to make a shot or pass.
A defender will often foul the player with the ball as a tactic to disrupt the opponent's ball movement. Play continues uninterrupted in most cases, but the attacker must now pass the ball or continue swimming instead of taking a shot. (An exception allows players to quickly pick up the ball and shoot if fouled outside of the five meter mark.) However, as in ice hockey, a player caught committing a major foul, is sent out of the playing area with his team a man down for 20 seconds, but may return sooner if a goal is scored or his team regains possession. If the foul is judged to be brutal, the player is ejected for the remainder of the game, with substitution by another teammate after four minutes have elapsed. A player, coach or spectator can also be ejected for arguing with the referees. During a man up situation resulting from an ejection foul, the attacking team can expect to score by passing around to move the goalkeeper out of position. A player that has been ejected three times must sit out the whole match with substitution.

[edit]Basic skills

Water Polo is a team water activity requiring swimming skills. Players must play both offense and defense, treading water or wrestling before turning back for the opposing team's possession. The front crawl stroke used in water polo differs from the usual swimming style in which water polo players swim with the head out of water at all times to observe the play. The arm stroke used is also a lot shorter and quicker and is used primarily to protect the ball. Backstroke is used by defending players to look for advancing opponents and by the goalie to track the ball after passing. Water polo backstroke differs from swimming backstroke; the player sits up a bit in the water, using eggbeater leg like motions with short arm strokes to the side instead of long arm strokes. This allows the player to see the play and quickly switch positions. It also allows the player to quickly catch a pass.

As all field players are only allowed to touch the ball with one hand at a time, they must develop the ability to catch and throw the ball with either hand and also the ability to catch a ball from any direction, including across the body using the momentum of the incoming ball. Experienced water polo players can catch and release a pass or shoot with a single motion. The size of the ball can overwhelm a small child's hand, making the sport more suitable for older children. There are also smaller balls that can be used by younger children when playing.
  • Treading water: The most common form of water treading is generally referred to as "egg-beater",[13] named because the circular movement of the legs resembles the motion of an egg-beater. Egg-beater is used for most of the match as the players cannot touch the bottom of the pool. The advantage of egg-beater is that it allows the player to maintain a constant position to the water level, and uses less energy than other forms of treading water such as the scissor kick, which result in the player bobbing up and down. It can be used vertically or horizontally. Horizontal egg-beater is used to resist forward motion of an attacking player. Vertical egg-beater is used to maintain a position higher than the opponent. By kicking faster for a brief period, the player can get high out of the water (as high as their suit—below their waistline) for a block, pass, or shot.
  • Reflexes and Awareness: At higher levels of the sport the pace of play rapidly increases, so that anticipation and mental preparation is important. "Field sense" is a major advantage in scoring, even if a player lacks the speed of an opponent.[14]

[edit]Positions

There are seven players in the water from each team at one time. There are six players that play out and one goalkeeper. Unlike most common team sports, there is little positional play; field players will often fill several positions throughout the game as situations demand. These positions consist of the center (or hole set), the point (who also usually plays center back or hole defender), the two wings and the two flats. Players who are skilled in all of these positions on offensive or defensive are called utility players. Utility players tend to come off of the bench, though this is not absolute. Certain body types are more suited for particular positions, and left-handed players are especially coveted on the right-hand side of the field, allowing teams to launch 2-sided attacks.

[edit]Offense

The offensive positions include: one center (a.k.a. two-meter offense, 2-meters, hole set, set, hole man, bucket, pit player or pit-man), two wings (located on or near the 2-meter), two drivers (also called "flats," located on or near the 5-meter), and one "point" (usually just behind the 5 meter), positioned farthest from the goal. The wings, drivers and point are often called the perimeter players; while the hole-set directs play. There is a typical numbering system for these positions in U.S. NCAA men's division one polo. Beginning with the offensive wing to the opposing goalies right side is called one. The flat in a counter clockwise from one is called two. Moving along in the same direction the point player is three, the next flat is four, the final wing is five, and the hole set is called six.
The most basic positional set up is known as a 3–3, so called because there are two lines in front of the opponent's goal. Another set up, used more by professional teams, is known as an "arc," umbrella, or mushroom; perimeter players form the shape of an arc around the goal, with the hole set as the handle or stalk. Yet another option for offensive set is called a 4–2 or double hole; there are two center forward offensive players in front of the goal. Double hole is most often used in "man up" situations, or when the defense has only one skilled hole D, or to draw in a defender and then pass out to a perimeter player for a shot ("kick out").
The center sets up in front of the opposing team's goalie and scores the most individually (especially during lower level play where flats do not have the required strength to effectively shoot from outside or to penetrate and then pass to teammates like the point guard in basketball). The center's position nearest to the goal allows explosive shots from close-range ("step-out" or "roll-out", "sweep," or backhand shots).
Another, albeit less common offense (violation), is the motion offense in which two "weak-side" (to the right of the goal for right-handed players) perimeter players set up as a wing and a flat. The remaining four players swim in square pattern in which a player swims from the point to the hole and then out to the strong side wing. The wing moves to the flat and the flat to the point. The weak side wing and flat then control the tempo of play and try to make passes into the player driving towards the center who can then either shoot or pass. This form of offense is used when no dominate hole set is available, or the hole defense is too strong. It is also seen much more often in women's water polo where teams may lack a player of sufficient size or strength to set up in the center. The best advantage to this system is it makes man-coverage much more difficult for the defender and allows the offense to control the game tempo better once the players are "set up." The main drawback is this constant motion can be very tiring as well as somewhat predictable as to where the next pass is going to go.

[edit]Defense

Defensive positions are often the same positionally, but just switched from offense to defense. For example, the centre forward or hole set, who directs the attack on offense, on defense is known as "hole D" (also known as set guard, hole guard, hole check, pit defense or two-meter defense), and guards the opposing team's center forward (also called the hole). Defense can be played man-to-man or inzones, such as a 2–4 (four defenders along the goal line). It can also be played as a combination of the two in what is known as an "M drop" defense, in which the point defender moves away ("sloughs off") his man into a zone in order to better defend the center position. In this defense, the two wing defenders split the area furthest from the goal, allowing them a clearer lane for the counter-attack if their team recovers the ball.

[edit]Goalie

Goalkeeper blocking a shot
The goalkeeper is generally one of the more challenging positions not only in the sport of water polo, but in any sport. A goalie has to be able to jump out of the water, using little more than one's core and legs, and hold the vertical position without sinking into the water, all while tracking and anticipating a shot. The goal is 2.8 m2 in face area; the goalie should also be a master of fast, effective lateral movement in the water as well as lightning fast lunges out of the water to block a shot. Another key job that the goalkeeper is responsible for is guiding and informing his or her defense of imposing threats and gaps in the defense, and making helpful observations to identify a gap in the defense that the defenders may or can not see. The goalkeeper is also the "quarterback", as he or she usually begins the offensive play. It is not unusual for a goalie to make the assisting pass to a goal on a break away.
The goalkeeper is given several privileges above those of the other players, but only if he or she is within the five meter area in front of his or her goal:[15]
  • The ability to punch the ball with a clenched fist.
  • The ability to touch the ball with two hands.
  • The ability to touch the bottom of the pool. (Pool depth permitting - most competitions state the pool has to be at least 2 meters deep)[16]
However, the goalkeeper is restricted to his or her half of the pool.[15]
In general, a foul that would cause an ejection of a field player might only bring on a five meter shot on the goalie. The goalkeeper also has one limitation that other players do not have: he or she cannot cross the half-distance line. Also, if a goalie pushes the ball under water, it is not a turnover like with field players. It is a penalty shot, also called a 5-meter shot, or simply, a "5-meter".

[edit]Offense strategy

[edit]Starting play of each of the quarters (usually four without overtime)

The sprint (swimoff).
At the start of each period, teams line up on their own goal line. Three players go to both sides of the goal; the goalkeeper starts in the goal. At the referee's whistle, both teams swim to midpoint of the field (known as the sprint or the swim-off); the referee drops the ball near the side of the pool (in American water polo). In International competition the ball is placed in the middle of the pool and is supported with a floating ring. The first team to recover the ball becomes the attacker until a goal is scored or the defenders recover the ball. After a goal is scored, the teams line up anywhere within their halves of play, but usually along the midpoint of the pool. Play resumes when the team not scoring the goal puts the ball in play by passing it backwards to a teammate.

[edit]Advancing the ball

When the offense takes possession of the ball, the strategy is to advance the ball down the field of play and to score a goal. Players can move the ball by throwing it to a teammate or swimming with the ball in front of them ("dribbling"). If an attacker uses his arm to push away a defending player and free up space for a pass or shot, the referee will rule a turnover and the defense will take possession of the ball. If an attacker advances inside the 2-meter line without the ball or before the ball is inside the 2-meter area, he is ruled offside and the ball is turned over to the defense. This is often overlooked if the attacker is well to the side of the pool or when the ball is at the other side of the pool.

[edit]Setting the ball

The key to the offense is to accurately pass (or "set") the ball into the center forward or hole set, positioned directly in front of the goal (the hole). Any field player may throw the hole set a "wet pass." A wet pass is one that hits the water just outside of the hole set's reach. A dry pass may also be used. This is where the hole set receives the ball directly in his hand and then attempts a shot at the cage. This pass is much more difficult because if the pass is not properly caught, the officials will be likely to call an offensive foul resulting in a change of ball possession. The hole set attempts to take possession of the ball [after a wet pass], to shoot at the goal, or to draw a foul from his defender. A minor foul is called if his defender (called the "hole D") attempts to impede movement before the hole set has possession. The referee indicates the foul with one short whistle blow and points one hand to the spot of the foul and the other hand in the direction of the attack of the team to whom the free throw has been awarded. The hole set then has a "reasonable amount of time" (typically about three seconds) to re-commence play by making a free pass to one of the other players. The defensive team cannot hinder the hole set until the free throw has been taken, but the hole set cannot shoot a goal once the foul has been awarded until the ball has been played by at least one other player. If the hole set attempts a goal without the free throw, the goal is not counted and the defense takes possession of the ball, unless the shot is made outside the 5-meter line. As soon as the hole set has a free pass, the other attacking players attempt to swim (or drive) away from their defenders towards the goal. The players at the flat position will attempt to set a screen (also known as a pick) for the driver. If a driver gets free from a defender, the player calls for the pass from the hole set and attempts a shot at the goal.
A classic 4–2 man-up situation. The attacking white team has 4 players positioned on 2 meters, and 2 players positioned on 4 meters. The 5 outfield defending blue players try to block shots and prevent a goal being scored for the 20 seconds of man-down play. In the top left corner, the shot clock can be seen, showing 28 seconds remaining in the white attack.

[edit]Man up (6 on 5)

If a defender interferes with a free throw, holds or sinks an attacker who is not in possession or splashes water into the face of an opponent, the defensive player is excluded from the game for twenty seconds (informally called a 'kicked out' or an ejection). The attacking team typically positions 4 players on the 2 meter line, and 2 players on 5 meter line (4–2), passing the ball around until an open player attempts a shot. Other formations include a 3–3 (two lines of three attackers each) or arc (attackers make an arc in front of the goal and one offensive player sits in the 'hole' or 'pit' in front of the goal). The five defending players try to pressure the attackers, block shots and prevent a goal being scored for the 20 seconds while they are a player down. The other defenders can only block the ball with one hand to help the goalie. The defensive player is allowed to return immediately if the offense scores, or if the defense recovers the ball before the twenty seconds expires.

[edit]Five meter penalty

Five meter penalty shooting
If a defender commits a major foul within the five meter area that prevents a likely goal, the attacking team is awarded a penaltythrow or shot.[5] An attacking player lines up on the five meter line in front of the opposing goal. No other player may be in front of him or within 2 meters of his position. The defending goalkeeper must be between the goal posts. The referee signals with a whistle and by lowering his arm, and the player taking the penalty shot must immediately throw the ball with an uninterrupted motion toward the goal without pumping or faking. The shooter’s body can not at any time cross the 5 meter line until after the ball is released. If the shooter carries his body over the line and shoots the result is a turn over. If the shot does not score and the ball stays in play than the play continues. Penalty shots are often successful, with 63.7% of shots being scored from them.[17][18]

[edit]Scoring

A goal is scored if the ball completely passes between the goal posts and is underneath the crossbar.[7] If a shot bounces off a goal post back into the field of play, the ball is rebounded by the players and the shot clock is reset. If the shot goes outside the goal and on to the deck (outside the field of play) then the ball is automatically recovered by the defense. If the goalie, however, is the last to touch the ball before it goes out of play behind the goal line, or if a defender purposely sends the ball out, then the offense receives the ball at the two meter line for a corner throw or "two meter" much like a corner kick in soccer or football. When the goalie blocks a shot, the defense may gain control of the ball, and make a long pass to a teammate who stayed on his offensive end of the pool when the rest of his team was defending. This is called cherry-picking or sea gulling.

[edit]Overtime

FINA
If the score is tied at the end of regulation play, two overtime periods of three minutes each are played. If the tie is not broken after two overtime periods, a penalty shootout will determine the winner. Five players and a goalkeeper are chosen by the coaches of each team. A player cannot be chosen if he or she was ejected three times during the match. Players shoot from the 5 meter line alternately at either end of the pool in turn until all five have taken a shot. If the score is still tied, the same players shoot alternately until one team misses and the other scores. Overtime periods are common in tournament play because of the high level of skill of these superior teams.
NCAA
Differing from FINA rules, after the two three-minute overtime periods in American college varsity water polo, the teams play three-minute sudden death periods until a team scores a goal and wins the game.[19]
NFHS
American High School water polo plays overtime as a "sudden death" period of a specified time limit. If this results in a tie, the teams engage in a shootout as described in FINA rules above.

[edit]Defense strategy

Water polo defense: A defender may only hold, block or pull an opponent who is touching or holding the ball.
On defense, the players work to regain possession of the ball and to prevent a goal in their own net. The defense attempts to knock away or steal the ball from the offense or to commit a foul in order to stop an offensive player from taking a goal shot. The defender attempts to stay between the attacker and the goal, a position known as inside water.

[edit]Advantage rule

If an offensive player, such as the hole set (center forward), has possession of the ball in front of the goal, the defensive player tries to steal the ball or to keep the center from shooting or passing. If the defender cannot achieve these aims, he may commit a foul intentionally. The hole set then is given a free throw but must pass off the ball to another offensive player, rather than making a direct shot at the goal. Defensive perimeter players may also intentionally cause a minor foul and then move toward the goal, away from their attacker, who must take a free throw. This technique, called sloughing, allows the defense an opportunity to double-team the hole set and possibly steal the inbound pass. The referee may refrain from declaring a foul, if in his judgment this would give the advantage to the offender's team. This is known as the Advantage Rule.[20]

[edit]Fouls

Ordinary fouls occur when a player impedes or otherwise prevents the free movement of an opponent who is not holding the ball. The most common is when a player reaches over the shoulder of an opponent in order to knock the ball away while in the process hindering the opponent. Offensive players may be called for a foul by pushing off a defender to provide space for a pass or shot. The referee indicates the foul with one short whistle blow and points one hand in the direction of the attacking team (standing roughly in line with the position of the foul), who retain possession. The attacker must make a free pass without undue delay to another offensive player. If the foul has been committed outside the 5-meter line, the offensive player may also attempt a direct shot on goal, but the shot must be taken immediately and in one continuous motion. Because of this rule the hole set will often set up at or beyond the five meter mark hoping to get a foul, shoot, and score. If the offensive player fakes a shot and then shoots the ball, it is considered a turnover. If the same defender repetitively makes minor fouls, referees will exclude that player for 20 seconds. To avoid an ejection, the hole defender may foul twice, and then have a wing defender switch with him so that the defense can continue to foul the hole man without provoking an exclusion foul. The rule was altered to allow repeated fouls without exclusions, but is often still enforced by referees.
Major fouls (exclusion fouls) are committed when the defensive player holds, sinks or pulls back the offensive player away from the ball before the offensive player has had a chance to take possession of the ball. This includes dunking (sinking in FINA rules), intentional splashing, pulling back, swimming on the other player's back,stopping the other player from swimming or otherwise preventing the offensive player from preserving his advantage. A referee signals a major foul by two short whistle bursts and indicates that the player must leave the field of play and move to the penalty area for twenty seconds. The referee will first point to the player who commits the foul and will blow the whistle, then they will point to the ejection corner and blow the whistle again. The player must move to the penalty area without impacting the natural game play. If the player does not leave the field of play, the player will be kicked out for the remaining time of the game with substitution. The remaining five defenders, to cover the six attackers on a man up situation, usually set up in a zone defense in front of their goal. The attacking team can expect to score, by adopting a 4–2 or 3–3 formation, and moving the goalkeeper out of position. A player that has been ejected three times must sit out the whole match with substitution, much like the six personal fouls in basketball.
Drawing the ejection (forcing defense to commit a major foul) occurs when an offensive player takes advantage of a defensive player by using body position and/or grabbing on their wrists to make it appear as though the defensive player is committing a "major foul", therefore resulting in the ejection of that player and gaining a 6 on 5 advantage. Another common way to draw an ejection is by staggering stroke while being chased to make it appear as though the defensive player is pulling the swimmer back.
Brutality fouls A brutality is called when a player kicks or strikes an opponent or official with malicious intent. The strike must make contact with the player for a brutality to be called, and must be with intent to injure. Otherwise the player is punished with a misconduct foul, with substitution allowed after 20 seconds or a change of position. The player who is charged with a brutality is excluded from the game for 4 minutes, and the team is forced to play with one less player than the other team for that duration. In addition to the exclusion a penalty shot is also awarded to the opposing team, if the foul occurs during actual play. Previously, the team who was charged with a brutality would be required to play the remainder of the game with one less player, similar to a red card awarded in football. All brutalities have to be reported by officials and further actions may be taken by the relevant governing body. These actions could include more games added on to the one game suspension.
misconduct foul is an unsportsmanlike act. For unacceptable language, violence or persistent fouls, taking part in the game after being excluded or showing disrespect, a player is ejected for the remainder of the game with substitution after 20 seconds has elapsed. There are two kinds of misconduct fouls that a player can incur. If a player physically assaults another player and the referee deems it not to be severe enough to warrant a charge of brutality, the lesser charge being Misconduct-Violence can be applied. If the incident does not involve physical (or attempted) contact, the referee can impose a Misconduct charge. In most competitions Misconduct-Violence carries heavier sanctions than Misconduct.
penalty shot or 5-meter is awarded when a major foul is committed inside the 5-meter line and a probable goal was prevented by the foul. This is usually awarded if the defensive player in on another players back. This usually means that the offensive player is in front of and facing the goal. The penalty shot is attempted from 5 meters. Any defenders flanking the player taking the shot must be no closer than 2 meters. The goalkeeper must be on the goal line. In high school rules, the goalie must keep their hips even with the goal line. They are allowed to lean their upper body over in order to kick up higher. The referee blows the whistle and the player must shoot immediately.

[edit]Goalkeeper

Even with good backup from the rest of the defenders, stopping attacks can prove very difficult if the goalkeeper remains in the middle of the goal. The most defensible position is along a semicircular line connecting the goalposts and extending out in the center. Depending on the ball carrier's location, the goalie is positioned along that semicircle roughly a meter out of the goal to reduce the attacker's shooting angle. The goalkeeper stops using his or her hands to tread water once the opponent enters at about the 7 meter mark and starts treading water much harder, elevating the body, arms ready for the block. Finally the goalie tries to block the ball down, which is often hard for the longer reaches, but prevents an offensive rebound and second shot. As is the case with other defensive players, a goalkeeper who aggressively fouls an attacker in position to score can be charged with a penalty shot for the other team. The goalkeeper can also be ejected for twenty seconds if a major foul is committed. Also inside the five meter mark, the goalie can swing at the ball with a closed fist without being penalized.
