Funny US Open video with Nicole Vaidisova, challenge problem
Seed No.13 Nicole Vaidisova had an amusing problem with the challenge system in her first round match against Russian Alla Kudryavtseva — the ball was clearly in, but it was called out! Uh, even challenges need to be challenged.
Additional info: Vaidisova defeated Kudryavtseva 6-1 6-2, and her opponent in the second round will be Flavia Pennetta of Italy. (via Tennis Videos)
