Water polo positions explained: goalkeeper, center, wings, drivers & set defender
Seven players in the water, five named field positions, and one of the most physically demanding role-divisions in any team sport. Here's what each player actually does — and what to watch for.

Most people who walk into their first water polo game can spot the goalkeeper and lose track of everyone else inside thirty seconds. This post fixes that: the seven positions, how to recognize each one in the water, what they’re actually trying to do, and the small details that separate casual watching from understanding the game.
1. Position overview: 7 in the water
The 7 positions at a glance
Field players split into 5 named roles: center (1), wings (2), drivers (2), and set defender (1). A full roster carries 13 — 7 in the water, 6 on the bench, with free substitution after every goal, between quarters, and during dead time.
Water polo is played with 7 players per team in the water at once: one goalkeeper and six field players. Unlike soccer or hockey, the field positions aren’t hard-locked — on offense, players rotate, swap, and screen constantly. But every team builds its offense around five named positions: one center, two wings, two drivers, and a set defender (who plays a hybrid offensive role on attack and defends the opposing center on defense).
You can spot the goalkeeper instantly: they wear a red cap with the number 1, they’re the only player who stays inside their own 5-meter line, and they’re allowed to use both hands on the ball when they’re inside that 5-meter line. Everyone else wears white caps (home) or dark blue caps (visitor) numbered 2 through 13. The numbers are loose conventions — the center often wears 4 or 5, the goalkeeper always wears 1 (and a backup goalkeeper wears 13) — but cap numbers do not lock a player into a position.
The basic offensive shape
When a team sets up on offense, the most common formation is the “umbrella”: the center sits at 2 meters directly in front of the goal, the two wings flare to the goal-line corners, the two drivers float at the 5-meter line on either flank, and the set defender plays the point at the top of the umbrella. Picture an umbrella opened over the goal — that’s the shape. From here the offense can swing the ball around the perimeter, drive the ball into the center, set screens, or kick out for an outside shot.
2. Goalkeeper
The goalkeeper (cap number 1, red cap) is the most physically distinct position in the sport. They face 25 to 35 shots per game from inside 6 meters, and a save percentage swing of 10 points can decide a close match. Goalkeepers are typically the tallest players on the team — arm span matters more than nearly any other physical attribute — and they spend the entire game treading water with a powerful eggbeater kick that lifts the whole upper body out of the water on every shot.
What makes their game different
Two hands on the ball. The goalkeeper is the only player who can touch the ball with two hands at once — but only inside their own 5-meter line. Outside the 5m, two hands is a turnover.
Cannot cross half-court with the ball. They can swim past half-court without the ball, but if they hold the ball they have to stay in their own half.
Standing on the bottom is allowed, but only inside the 5m line and only for the goalkeeper.
4-meter rule. A foul on the goalkeeper inside their own 4-meter line is called differently than on field players — refs are more reluctant to award penalties.
What to watch for
A great goalkeeper does three things constantly: they read the shooter’s eyes (where the shooter looks is usually where they shoot), they spring laterally across the goal with explosive eggbeater bursts, and they start the counterattack the instant they save the ball. Watch what happens after a save — the best goalkeepers fire a long outlet pass to a sprinting wing for a fast-break goal in under five seconds. The save itself is half the play.
3. Center / Hole Set
The center — also called the hole set, 2-meter, set, or just “the 2” — plays directly in front of the opposing goal, about 2 meters out. This is the offensive heart of nearly every water polo team. The center has their back to the goal, fights for body position against a defender who’s often draped over them, and tries to receive the ball with a free hand to either turn-and-shoot or draw a foul.
What makes the position hard
The center spends the entire offensive possession in physical contact with the set defender. They’re getting grabbed, pushed under, leg-locked, and elbowed — legally, in most cases, because contact at the center position is part of the game. To survive there, centers need elite leg strength (the eggbeater has to hold them up against constant downward pressure), shoulders that can absorb contact, and the ability to feel where the defender is without looking. Most teams’ biggest, strongest player plays center.
What to watch for
The set-up pass. When the ball goes to the center, the offense holds its breath. Three things can happen: a quick turn-and-shoot, a draw of an exclusion (kickout), or a pass back out if the defender beats the position.
Earned exclusions. The center draws more kickouts than any other position by 3 to 4x. Watch the ref’s hand — if they signal a player out after the ball enters the hole, that’s an earned exclusion and the offense now has 20 seconds with a 6-on-5 advantage.
Sweep shots and back-hands. The center rarely has time to turn fully. The two signature shots are the sweep (a one-handed flick across the body) and the back-hand (shooting backward without turning). Both are released in under a second.
4. Wings
The two wings play the flanks — the outside positions closest to the goal line, roughly even with the 2-meter mark but pushed out to the sides of the pool. They are typically the team’s fastest swimmers because the wing job description includes sprinting the length of the pool on counterattacks. On offense they shoot from tight angles, set screens for the center, and crash for rebounds. On defense they pick up the opposing wings and play press defense.
The wing shot
A wing shot is taken from about 5 meters out at a sharp angle — maybe 20 to 30 degrees off the goal-line. It’s a hard shot to make because the angle to the far post is tight and the near post is right there waiting. Good wings either skip the ball (a bounce shot that arrives at the goalkeeper at an awkward height) or place it back-post, glass-on-the-far-side. Wings also score on rebounds off long shots, which is why coaches call “wing crashes the rebound” on every outside attempt.
What to watch for
Watch the wing on the counterattack. The instant a turnover or save happens, the two wings sprint up the side of the pool. If they beat their defender by even half a stroke, the goalkeeper or a defender will hit them with a long pass for a 1-on-0 attempt at the other end. Counter goals are some of the most exciting plays in water polo, and the wings are who make them happen.
5. Drivers / Outside Shooters
The two drivers — also called outside shooters, perimeter players, or 2’s and 4’s on some teams — play higher up the pool, on the perimeter at about 5 to 7 meters from the goal. They are the team’s strongest outside shooters, and their primary job on offense is to threaten the goal from outside while also driving (swimming directly at the goal) off a screen or a pass to force the defense to collapse.
Two modes: shoot or drive
The name “driver” is a little misleading — drivers don’t always drive. On every possession, a driver chooses one of three things:
- Shoot from outside. A driver with the ball at 6 meters with a defender a half-arm-length back has the green light to shoot. Most goals from outside are scored by drivers.
- Drive past the defender. If the defender pressures up, the driver pushes the ball forward and sprints around them toward the goal — either to get a closer shot or to draw a foul.
- Pass into the hole. If the center has position, the driver swings the ball in for a hole feed.
What to watch for
Drivers are where you’ll see the most spectacular shots. The classic outside water polo shot — the player rises out of the water on a powerful eggbeater, cocks the ball back over their head, and rips a 50 mph shot top-corner — that’s a driver. Watch for the eggbeater height (top drivers get their chest fully out of the water on a shot) and the placement (good drivers don’t shoot middle; they pick a corner).
6. Set Defender / Hole D
The set defender — also called the hole D, point, or 2-meter defender — has the hardest defensive job in the sport. They guard the opposing center, which means they spend the entire defensive possession in physical contact, fighting to deny the center position, ball, and shot from a player who often outweighs them.
The defensive job
The set defender’s first job is fronting — positioning themselves between the ball and the center to deny the entry pass. If the pass gets in, they switch to back-defense: contesting the center’s turn-and-shoot, blocking the sweep, and trying to draw an offensive foul. A set defender who gets called for three exclusions is benched for the rest of the game (the “3-strike rule”), so they have to play hard but smart. The hardest skill in the sport is probably the set defender’s: defending the hole without committing a 20-second exclusion.
The offensive job (sometimes)
On offense, the same player typically plays the point position at the top of the umbrella, 6 to 7 meters out. They’re a secondary outside shooter and the most common entry passer into the center. So the “set defender” plays defense at 2m and offense at 7m — the largest territorial range of any position on the team. Some teams substitute a different player into the point role on offense to keep the set defender fresh, but most don’t.
One position name, lots of aliases. Water polo terminology varies by country and coach. The center is called the hole set, set, 2-meter, center forward, or just the 2. The set defender is the hole D, point, 2-meter defender, or anchor. The drivers are outside shooters, perimeter players, flats, or 2’s and 4’s. If you hear a coach yell “set the ball” they mean pass to the center; “drive” means swim at the goal; “kick out” means an exclusion just happened.
7. Bench & substitutions
A water polo roster carries 13 players: 7 in the water and 6 substitutes. Substitution is free — players can swap in and out at any of three times:
- After every goal, before the next restart at half-court.
- Between every quarter, including halftime.
- After a timeout, of which each team gets two per game (sometimes three at NCAA).
- During the 20-second exclusion window, but only if the excluded player’s team substitutes before the excluded player returns.
The free-sub rule means most teams rotate aggressively. A typical senior FINA team might rotate 11 or 12 of its 13 players through every game, with the goalkeeper and the starting center playing the most minutes. Youth teams often rotate the entire roster every quarter to keep everyone fresh and engaged.
Position-specific rotations
Most teams carry one starting goalkeeper plus one backup, two centers (because the position is so physically punishing), and a deeper pool of drivers and wings. If you’re watching the bench, the player warming up next is almost always either a fresh center to replace a tired one, or a designated outside shooter being subbed in for a specific play (a 6-on-5 power play in particular).
Position quick-reference table
The cheat sheet, all in one place:
| Position | Cap # | Primary role | What to watch |
|---|---|---|---|
| Goalkeeper | 1 (red cap) | Save shots; start the counterattack | Eggbeater height on saves; outlet passes after the save |
| Center / Hole Set | 4 or 5 (loose convention) | Score from 2m; draw exclusions; absorb contact | Sweep shots and back-hands; earned kickouts |
| Wings (×2) | 2 & 6 (loose) | Sprint counters; tight-angle shots; rebound crashes | Counter-attack sprints; back-post shots |
| Drivers (×2) | 3 & 7 (loose) | Outside shots; drive moves; feed the center | 50mph top-corner outside shots; drive-and-draw fouls |
| Set Defender / Hole D | 5 or point (loose) | Defend the hole; play the point on offense | Fronting battle with the opposing center; not getting 3 kickouts |
| Bench | 8–13 | Free substitution at goals, quarters, timeouts | Who’s warming up — that’s often who’s coming in |
Five things spectators get wrong on first watch: (1) thinking the goalkeeper can never leave the 5m — they can, just without two hands on the ball; (2) thinking the center stays put — the center swims and rotates constantly out of the hole; (3) thinking exclusions are penalties — they’re a 20-second power play, not a goal-line foul; (4) confusing the set defender with the center — they’re guarding each other, but at opposite ends; (5) assuming cap numbers map to positions like a soccer 9 or a hockey 4 — in water polo, numbers are mostly cosmetic.
How positions shift during a 6-on-5 power play
When a player is excluded for 20 seconds, the offense gets a one-player advantage and the positions reorganize into a fixed shape. The two most common 6-on-5 formations:
3-3 formation
Three players line up across the 2-meter line (left post, center, right post) and three across the 5-meter line (left, top, right). The center stays in the hole, the wings drop to the goal-line corners, and the drivers plus set defender float at 5m looking to shoot or feed. This is the classic 6-on-5 shape and it converts at 40 to 60 percent at senior levels.
4-2 formation
Four players across the 2-meter line, two players up top at 5m. Used when a team has a height/strength mismatch at the post and wants to overload the close-range scoring zone. Lower outside-shot percentage but very high inside conversion. Often used at youth levels where shooters can’t yet rip the ball from 7m.

Frequently asked questions
A water polo team has 7 players in the water at any time — 1 goalkeeper and 6 field players. The 6 field players are conventionally grouped into 5 named positions: the center (hole set), two wings, two drivers, and the set defender (hole D, also called the point or 2-meter defender). A full roster carries 13 players: 7 in the water plus 6 substitutes.
Coaches will tell you the goalkeeper. The goalkeeper faces 25 to 35 shots per game, and a save percentage swing of 10 points (from 50 percent to 60 percent) can decide a close match. After the goalkeeper, the center (hole set) is usually considered the offensive heart of the team — most plays run through them, they draw the most fouls, and they convert the most goals from close range.
Yes. A goalkeeper can swim or pass the ball past half-court and shoot just like any field player — and they sometimes do, especially during a 6-on-5 power play or in the final seconds of a quarter. Under World Aquatics rules the goalkeeper just cannot cross half-court with the ball in their hand, and cannot touch the ball with two hands outside their own 5-meter line.
The set is another name for the center position — the player who plays directly in front of the opposing goal, about 2 meters out. Some teams call this player the hole set, the center forward, the 2-meter, or simply the 2. The player guarding them is the set defender or hole D. When you hear a coach yell “set the ball,” they mean pass the ball to the center in that hole position.
Wings play the flanks — the two outside positions closest to the goal line. They shoot from a tight angle, set screens for the center, and crash for rebounds. Drivers play higher up the pool, on the perimeter at about 5 to 7 meters out. Their job is to drive toward the goal off the pass, draw exclusions, and shoot from outside. Drivers are usually the team’s strongest perimeter shooters; wings are typically the quickest swimmers.
In a 6-on-5 power play (after the other team is excluded for 20 seconds) the offense reorganizes into a fixed shape — usually a 3-3 (three players on the 2-meter line, three on the 5-meter line) or a 4-2 (four players across the 2-meter line, two up top). The center stays in the hole, the wings drop to the goal line, and the drivers and set defender become the outside shooters. The defending team plays a sliding zone, which is why the 6-on-5 conversion rate is one of the most-tracked stats in water polo.
