June 7, 2012, 8:42 am Thanks to some odd scheduling, Thursday is the first day of the 2012 French Open on which only one court will be used for singles. And what a day it should be. First up is No. 6 Samantha Stosur vs. No. 21 Sara Errani. Stosur, the reigning U.S. Open champion, is looking to reach her second French Open final and has won all six previous meeting against Errani. Errani is in her first Grand Slam singles semifinal, and is hoping to become the first woman since Kim Clijsters in 2003 to make both the singles and doubles finals in Paris. That match is followed by the more highly anticipated showdown between No. 2 Maria Sharapova and No. 4 Petra Kvitova. The two power players have split their two most recent meetings at Grand Slam tournaments, with Kvitova winning the 2011 Wimbledon final and Sharapova winning the 2012 Australian Open semifinal.
