What is four ball in golf?

Four ball in golf is a format of play in which two golfers compete as partners against another pair of golfers. Each golfer plays their own ball throughout the round and the lowest score of the partners is used as the team's score for each hole. Four ball is commonly played in match play competitions, with the team with the lowest score on each hole winning the hole. This format allows for more aggressive play as each partner can play their own game and take more risks, knowing that their partner's score can still be used if their own score is not ideal. Four ball is a popular format for team events and can be played in both stroke play and match play formats.
