“I’m really looking forward to it,” Kohlschreiber said. “I’ve had some good matches against him, especially on hard courts. Basically I know a little bit how I have to play. We don’t have to say he’s in pretty good shape winning almost every match on hard court. So it’s going to be really tough, but I’m really looking forward to playing on Ashe. And I’m happy with my performance today. I think I also will play a really good match against him.”
