At the WTA championships when Petra Kvitova blasted Wozniacki off the court she complained of being tired. But Wozniacki is supposed to be a top atlhete and she's young. Now, Wozniacki lost to her good friend Aggie Radwanska and she has a wrist injury. I am not disputing that Wozniacki's wrist hurt I just think it is really tacky of her to use that excuse for her loss. Did Caroline forget she served for the match 5-4 up in the second set? Enough with the excuses. The Australians have a famous saying if you are on the tennis court you are fit. Excuses make Wozniacki look very weak and also someone that is crumbling under the pressure.
