I think fitness will come into play on this match. Knapp got a full two days rest while Beck has to return in 24 hrs after a hard three setter yesterday. Some of these WTA players dont have the fitness like the top tier players and don't play well on 24 hrs rest. Knapp will also have revenge on the mind after getting beat by Beck just last month. I feel she will be the fresher of the two and will have a couple of units on the Italian.
Match starts in about 30 minutes .....best of luck.
