It is considered a good return in tennis if:
- The ball touches the net, net posts (or single sticks), net cord, net strap, or net band and then passes over them and hits the ground inside the correct court.
- The ball in play has hit the ground inside the correct court and has spun, or been blown back over the net.
- The player reaches over the net and plays the ball into the correct court without touching the net.
- The ball is returned outside the net posts (either above, or below net level) and lands in the correct court. This rule applies even if the ball touches the net post, but lands in the correct court.
- The ball is returned under the net cord between the singles stick and adjacent net post and hits the ground inside the correct court.
- The player’s racket passes over the net after hitting the ball into the correct court.
- The player hits the ball in play, which hits another ball lying in the correct court.
