I haven't played much since Wimbledon. I've been staying in shape, though, and putting in a lot of work on fitness,
I can still play better. I'm playing a lot calmer now. I'm not worried about trying to win every point or win the match in every point. I'm kind of just staying a little bit even keel, and I'm serving 10 times better than I have been this year, which is a big, big plus for me.
