I have searched everywhere on the internet and have not found a reference to this situation. It's a USTA doubles match. The ball is hit to my partner who happens to be right in front of me. She has to stretch to make the shot and just misses the ball (or so she thought). I hear a very obvious 'tick' off the end of her racket and I am 100% convinced that she tapped it. Since the ball is now in front of me, I go ahead and make the shot successfully across the net and then waive the point off. I point out that we hit the ball twice and start to reset for the next point. My partner is not happy with me. She is 100% convinced she did not hit the ball. She thinks it is entirely her call or the opponents. She maintains that I do not have the obligation (or the right) to make the call. I am still convinced that she tapped it, but anything is possible and I may have made the wrong call. As I read the Code, when applying the logic of line calls in cases where we disagree, the point goes to the opponent. However, in this case, on 99.5% of the shots like this, she would know whether she hit it or not. So, she is saying that I did not have the right to stop the point. I called it as I saw it. Your opinions? Thanks.
