I knew that Petra Kvitova could be dangerous, but I was very surprised to see her take 6th seed Patty Schnyder out in the first round of the Zurich Open. Schnyder is playing extremely well these days, and she always shines on these indoor surfaces. But Kvitova upset her, 6-4, 3-6, 6-4.
Schnyder won Zurich in 2002. She played in the final in 2005, and was leading, but sustained a hand injury during the match and had to continue playing one-handed. Her level, of course, declined, and her opponent won. That opponent was Nadia Petrova, and Zurich 2005 was her first tour title.
Kvitova is currently ranked number 57 in the world.
