It's so hot, unbelievably humid, you get out of breath really quickly so I was happy to come through in two sets.I started to feel the ball better when I broke him early in the second. Against him it's so important to stay solid because he can produce some huge shots, get on a roll, and I was lucky that I didn't let him do that today."I changed the pace of the ball well and used the short slice and he didn't like that very much.
