Foursomes is a golf format that involves four players split into teams of two. In this format, each team uses only one ball, taking alternate shots until the hole is completed. One player will take the tee shot on odd-numbered holes, and the other on even-numbered holes. Foursomes is most commonly played as match play, with each hole being won by the team that completes it in the fewest shots. This format is often played in team golf competitions such as the Ryder Cup, Solheim Cup, and the Presidents Cup.
Foursomes is also known as alternate shot. It can be played in both match play and stroke play. The purpose of Rule 22 in the Rules of Golf is to cover Foursomes, where two partners compete together as a side by alternating in playing one ball.
Greensomes, also known as "Scotch foursomes," follows the same format as foursomes except that both players tee off on every hole. The better ball is chosen, and alternate strokes are then played to complete the hole. This format is used at the Bass Pro Shops Legends of Golf, where two rounds are played on a par three course; in each round, nine holes are played as greensomes and nine as better ball.
