Tennis no-nos

Here is a list of my tennis no-nos.  I’m going to see how making these mistakes (or not) correlates with success in the Wimbledon finals:

1) If you can’t hit a winner, don’t make an error.  (that one comes from Lindsay Davenport)

2) Don’t double fault in tiebreakers.

3) Don’t double fault on ad points.

4) If you’re on serve and fewer than 3 games have been played in a set, don’t challenge any call that is not on a game point.

5) If you’re down a break, don’t fail to get your opponent’s second serves into play.
