All four Grand Slam tennis tournaments will now use a 10-point tiebreaker when matches reach 6-6 in the final set.
The Grand Slam Board announced the trial move, taking effect immediately, on behalf of the Australian, French and U.S. Opens and Wimbledon on Wednesday.
“The Grand Slam Board’s decision is based on a strong desire to create greater consistency in the rules of the game at the Grand Slams, and thus enhance the experience for the players and fans alike,” it said.
