Recently, I played a singles match just after the rain stopped and the HarTru court was playable, but still damp; so the balls really picked up a lot of moisture and changed the game. What should you do?

Well, if it is just a “fun match,” you and your opponent can agree to change balls at any time. But if you can’t or don’t, the heavier balls will really start to impact the game. I think the conditions will favor the player who hits with more loopy topspin and/or is the retriever, because he will be able to get to more shots.

Here are some tips to consider:

• The Serve will come up short and frequently in the net; so serve deeper, and actually aim for the service line
• Footwork is critical. Stay on the balls of your feet and move them, otherwise the ball will come up short and you will be reaching for the shot
• Shot placement should be deeper than normal. Aim your shots deep in the court, otherwise it will be in the net
• Arm problems can be impacted in just one match. The really heavy balls will affect any arm weakness you already have.

Of course, you could always go drink a beer instead of playing in poor conditions!
