Teammates alternate tee shots. Player 'A' tees off on odd-numbered holes, and Player 'B' tees off on even-numbered holes. After the tee shot, teammates alternate shots until completion of the hole.
All four players play their own ball. The team whose player has the lowest score wins the hole. If the teams tie, they halve the hole. The team that wins the match receives one point, and if the teams tie they each get 1/2 point.
Players compete in match play head-to-head. The best score per hole wins that hole and tied holes are halved. The player who wins the match earns one point for his team. Ties are worth 1/2 point to each team.
There are 28 total matches and available points. The team with the most cumulative points at the end of the tournament wins. If the teams tie (14 vs.14) the team that last won the tournament retains the Ryder Cup trophy.
The Ryder Cup is played every other year, alternating locations between the United States and Europe. The 2010 Ryder Cup is to be played at The Celtic Manor in Newport, Wales.
