It was tough. Robby has a great return and he puts a lot of pressure on you when you serve. I was lucky I was serving well and didn't have a break point against me until the second set.
I am a bit tired because the points were really long and you have to run a lot because the bounce is really low. I had a lot of chances to break early in the second set. But the final set I was serving unbelievably and that was the key to the match.
