Best ball is one of the most straightforward tournament formats out there. Everyone's in two- or four-person teams, playing their own balls just as they would in a normal round. The twist? Only one player's score counts -- the lowest score on each hole is recorded as the team score. To keep teams from using the same player's score from every hole, there's usually a rule that says each player's score must be used a certain number of times -- even if it's not the lowest.
