Samantha Stosur stepped in as a replacement for ill defending champion Petra Kvitova, but was soon ushered out of the WTA Championships by Sara Errani, first-time qualifier, who lost to Maria Sharapova on Day 1, but has now earned her chance to fight for a spot in the semifinals. There will be a tough obstacle, though. Errani is 0-22 against Top 5 players and her next opponent in the White Group is world No.4 Agnieszka Radwanska.
Today Errani cruised to a 6-3 2-6 6-0 victory over Stosur, whose aggression paid off in the second set, but she failed to build up on the momentum and berried by a total of 49 unforced errors to Errani's 15 she lost the match, finalizing it with the seventh double fault. Their winners count was 44 for Stosur and 18 for Errani. It's interesting that Errani hit more aces than Stosur, although it is two aces to one.
Serena Williams and Maria Sharapova have certainly qualified for the prestigious semis, while the other two qualifiers will be determined in tomorrow's matches of Sara Errani vs. Agnieszka Radwanska (the second match on schedule) and Victoria Azarenka vs. Li Na (the third match on schedule). Friday's action opens with a match between Maria Sharapova and Samantha Stosur, but its outcome will not affect anything. (photo: © Neal Trousdale)
