Well hopefully Serena shows up ready to play Saturday wih her serve. I doubt she wants to lose a second time to the same player in a slam final. Must be engaged and at the ready. The first set is so important for Serena in that final.
The sisters won their doubles match beating the #4 seed Makarova and Vesnina. They are now into SF and there is a clear path to the title with no big name pairs still around.
