U.S. Open swings for instant replay

John McEnroe is certainly pleased. But with chair umps using Hawk-Eye tech to judge line calls, what'll he yell about?

Rules for Hawkeye Challenges

I think that the challenge rules are still somewhat fluid, but I think this is a more correct description of them (the article says "players have up to three challenges per set"):

Each player will receive two challenges per set to review line calls. If he is correct, he will retain the same number of challenges, but if he is incorrect, one will be lost. In addition, there is an additional challenge allowed in a tie-breaker (making up to three per set). The important distinction: A player has unlimited challenges, as long as he's always correct, or makes no more than one incorrect call (two if there is a tie-breaker).

Thanks

I was wondering the same thing. That is fair.

rules question

Does anyone know the full rules for Hawkeye instant replay? In particular, if a player thinks a shot is out and challenges it DURING the point (i.e., when he is still in a position to return the shot, but chooses to challenge it instead), does he lose the point, or is it replayed from the serve? I saw Blake do this the other day, he was correct and won the point, but if he had been wrong? If it would have lost him the point that means it was quite a gutsy call on his part.
