Trying to keep the ball in court to a good depth can reduce you to tears.
You start hitting it long. So you hit it softly. Too softly. You find the net. You hire a coach and spend, spend, spend. You love tennis, but you’re wondering if tennis loves you.
But topspin is not just for the pros!
You watch the pros. They seem to be able to hit groundstrokes at 80mph+ yet still keep it in! How? It’s topspin. It makes the ball dip back down into the court.
