Playing doubles, our opponents hit a shot that landed close to our baseline. I thought it could have been a little long but was not sure enough to call it so I internally pronounced it good and played it. Unfortunately, my shot went into the net. Just as it hit the net, my partner (at the net) said the previous shot was long and went on to show me the mark which indeed was out (we were playing on clay). Our opponents seemed fine with it being called long, but I felt we would be getting two bites at the apple, so I said I played it as a good ball, it was our fault that I didn't make it and that it was their point. Now I guess the thing about partners disagreeing on a call (leading to a point for opponents) doesn't apply here as there was the evidence of a ballmark. But was I right to insist on the "two applebites rule" when my partner made the call (although a little late)? I can also imagine it is not all that pleasant for the opponents to accept a point when they know they made an out shot. If it was in singles, I would not check the mark once I fully committed to my shot so the situation would not even arise. But should the call by partner change the outcome? As I only play doubles rarely, I would appreciate your suggestions on what to do if it happens again in the future.
