My tennis has been unbelievable.

I went home and got a tennis ball and started tossing it against a wall in my back yard to catch the rebounds. I'd go out there every day and throw that ball against a wall until I was catching every ball that bounced back. That's how I learned.

I was prepared for a tough match. In the second set, he started to serve much better. He started to come on and he had me under pressure.

The court was OK, I guess. There were a lot of people. Everywhere I play I find some fans and it is a big help.

He started to make a few returns and chip and charge. He started to come in on my second serve so he put me in some pressure.

Five days ago I was on holiday and having fun. Two days I didn't think I'm playing. Now I have a chance to be in the semi-finals. It's strange. Who knows?
