I almost always clear any missed serve of mine that goes into the net and rolls three or more feet back into the court. Bob, on the other hand, will frequently leave a ball sitting in the middle of the service box – or even closer to the service line.
The rule, I believe, is that he would have to pick up that ball, if I asked him to; but I don’t always ask.
And he admits that he frequently leaves the ball there because he knows I think about it.
When he leaves the ball on the court, I try not to let it bother me; but use it to my advantage by aiming near it or giving him a drop shot in that area. Trying to turn his intended distraction for me into a distraction for him.
This past week, we had one of those situations, where he left the missed first serve in the service box and we got into a ground stroke rally. On my first opportunity, I aimed my shot at his “sitting target,” and HIT IT!
The point was mine, because he left the ball on the court. And Bob said, “I guess I’ll have to start clearing the ball.”
