## 3. Doubles Appeal to Chair Umpire 

## STANDARDS SECTION XVIII - TOURNAMENT STANDARDS OF PERFORMANCE 

In doubles, the appealing player must make her appeal in such a way that either play stops or the Chair Umpire stops play.

Each player (team) shall receive three (3) incorrect challenges per set and one (1) extra challenge in case of a tie-break. In doubles, when a ten (10) point match tie-break is played in lieu of a final set, the number of challenges is reset to three (3) at the beginning of the match tie-break.
