Played dubs last night with some friends of mine - it was fun but very competitive. I cracked a sharp angled forehand return that landed in and pulled my one friend wide. We were playing at a set of courts where there is very little room between our court and the next court and no dividers. To get to the ball my opponent had to run onto the other court and nearly collided with the players on the other court (Ray Lewis style - LOL!). I though it was a winner, but he thought he could have gotten it back.In the end we played a let. It was kind of funny, but I was just wondering is there an offical rule for this situation?
