At the Australian Open, Roland-Garros, and the US Open, the 10-point tie-break will be played in lieu of the final set for mixed doubles, junior doubles and wheelchair doubles. At Wimbledon, the format will remain the same as for the other events.

Under this trial, if the score reaches six games all in the final set, the match winner(s) will be the first player(s) to win 10 points with an advantage of two or more points.
