Most of the matches weve played against each other went the distance, so Im going to be physically ready and fit. The key against him is trying to not allow him to dictate too much because he likes to be very aggressive, he likes to come to the net. Im going to have to be able to get as many returns back in the court and try to also stay closer to the line, protect the baseline."
