I was playing a match the other day and my opponent hit a ball that hits the net cord and bounds a few feet up. It then bounces within a foot of the net and then bounces over the height of the net and bounces for the second time on my side of the court. I'm pretty sure the first bounce was on my opponent's side but he thought it was on my side. Neither of us were 100% sure (he had gotten turned around and was still recovering, my head was bouncing as I was running into the net) on the call. We ended up replaying the point, but what would have happened if both sides were adamant that the ball bounced on their opponent's side first?
