Funny you should mention that.... I watched for about an hour, the Cal matches at Hellman this past Sunday.
But once again, YOU don't have a Open level serve. I did.
YOU didn't try to WIN against the woman, you only played your baseline game, which a 5.5 woman is far superior at over a 4.5 man. The man has to play a MAN'S game against the woman, not HER game against her.
You didn't dropshot and shortangle her constantly. YOU didn't hit into her body, come to net, and vary your approach half/low volleys.
You played baseline tennis, didn't you?
