Angelique Kerber did the seemingly impossible yesterday at the Western and Southern Open, beating Serena Williams on a surface other than a clay. The younger Williams had not lost since her first-round exit at the French Open to Virignie Razzano. Kerber did not seem to care how well Serena had been playing, as she took it to Williams and never took her foot off the gas. This upset, among others, makes the women's semifinals at the Western and Southern Open very intriguing.
Western and Southern Open
Na Li  vs. Venus Williams [WC]
Venus Williams fought past Samantha Stosur in the quarterfinals on Friday to reach her first single's semifinal of 2012. Her next task: to beat Na Li, should be considerably more difficult. Li, after losing early at both Wimbledon and the Olympics, travelled to Canada looking for some kind of momentum heading into the US Open. She found some, reaching the Final, only to lose to Petra Kvitova in a tough three-set match. She has continued that high level of play this week, beating Agnieszka Radwanska 6-1 6-1 in the quarters. I do think this will be a very tight match, but I expect the Chinese veteran to be a little too much for Venus. Nevertheless, this will be a great result for the elder Williams. Na Li in three.
Angelique Kerber  vs. Petra Kvitova 
As mentioned earlier, Angelique Kerber pulled off one of the biggest upsets of the year on Friday, dispatching Serena Williams in two stunningly easy sets. As for her opponent on Saturday, Petra Kvitova, the Czech woman has been on fire. After falling short of a medal at the Olympics a few weeks ago, Kvitova ran through the rest of the field in Canada to take the title. She has continued her torrid play in Ohio and will be a real factor in New York. Everything just seems to fall in place for her on hard courts. This particular match-up pits two hard-hitting lefties against one another. They play very similar styles and have similar strengths and weaknesses. Having said this, I believe Kvitova is playing too well right now. Petra in three entertaining sets.
Semifinals: Li d. Williams; Kvitova d. Kerber
Final: Kvitova d. Li in three sets (again).
Enjoy the final few days of the Western and Southern Open!
