The four positions: 1, 2, 3 and the back.

Numbers, not fixed places

The HPA describes the four outdoor positions as numbered roles rather than zones: players may go anywhere on the field. The Museum of Polo and Hall of Fame adds that players may swap roles temporarily during play. Arena polo is played three a side (see arena, snow and beach polo).

Meadow Brook Polo Club in the United States explains why the numbers line up front to back rather than side by side: if the player in front overruns the ball, a teammate behind can follow up and keep the attack going.

The four roles at a glance

No. 1: the forward

The HPA's description is short: No. 1 attacks and scores. The Museum of Polo calls No. 1 the attacking forward. Meadow Brook adds the defensive half of the job: once play starts, No. 1 marks the opposing No. 4, the other team's back.

No. 2: the link

The HPA describes No. 2 as balancing attack and defence. The Museum of Polo says No. 2 supports No. 1 going forward and defends against the opposing No. 3. Meadow Brook says the same about marking: once play starts, No. 2 picks up the other side's No. 3.

No. 3: the pivot

All three sources put No. 3 at the centre of the team. The HPA calls No. 3 the main strategist and usually the strongest hitter. The Museum of Polo calls the position the field general, launching attacks with long passes. Meadow Brook says No. 3 is typically the strongest player and the team's pivot.

The St. Moritz snow polo rules leaflet (2024) adds that the captain usually wears No. 3, with No. 4 defending and the other two attacking.

No. 4: the back

No. 4 is the defender, called the "back" by the HPA and Meadow Brook. The Museum of Polo describes the job as guarding the goal. Meadow Brook notes that No. 4 is usually a long hitter who takes the hit-ins (knock-ins) after the ball goes over the back line, and relies on strong backhands.

Two jobs for every player

Meadow Brook sums up each player's work as two jobs: in defence, mark your opposite number; in attack, get free of the player marking you. Read with the table above, the marking pattern is No. 1 on the opposing No. 4 and No. 2 on the opposing No. 3. The team play page covers how coaches teach players to work together.

The captain

Each team names a captain. Under the HPA's 2026 rules the captain is nominated to the umpires before the game, wears an armband and is the only player who may speak with them. Under the USPA's 2024 Outdoor Rules (Rule 1a) the captain alone represents the team on procedural matters with the umpires.

Shirt numbers

The HPA's 2026 rules require team shirts numbered 1, 2, 3 and 4, with no duplicates, on the back in a contrasting colour. The USPA's 2024 rule on jerseys (Rule 4b) deals with colour rather than numbering: shirts must be at least 75 percent one dark or one light colour.

Patrons and professionals

At the higher levels, many teams are built around a patron. Glion Institute's guide to polo describes patrons as amateur players who fund a team and play in it alongside professionals, typically three of them in higher-handicap tournaments. Cowdray Park Polo Club's report on the July 2026 Gold Cup final, for example, named a Best Patron for the winning team. According to Wikipedia, handicaps of 5 goals and above generally belong to professionals. The handicaps page explains how those ratings are set and why they shape who plays where.

Substitutes

The rulebooks allow players to be replaced, under conditions. The USPA's 2024 rules (Rule 3) allow unlimited substitutions at the end of any period, and mid-period substitution only when a player cannot continue; the highest team handicap fielded counts for the whole game. Under the HPA's 2026 rules (Rule 22) a team with an injured player gets up to 10 minutes to produce a substitute, and the injured player may later return at the start of a chukka.
