There was only one early singles match on Day 11 of the 2013 U.S. Open on Thursday, but it resulted in a major upset. No. 3 seed and defending champion Andy Murray was downed in three sets by No. 9 seed Stanislas Wawrinka, 6-4, 6-3, 6-2.
Wawrinka's dominant performance was a huge surprise considering the roll Murray had been on for nearly a year, and the struggles Wawrinka had been having in the tournaments leading up to the U.S. Open.
Wawrinka hadn't won more than one match in a tournament since he lost in the finals of the ATP Topshelf Open in June to Nicolas Mahut. The 28-year-old from Switzerland felt confident heading into the match.
He expressed as much to Kevin Mitchell of The Guardian prior to the match with Murray.
"I am sure he will not be 100 percent confident because he knows how well I can play and he has had some difficult matches against me."
Murray certainly never seemed confident as Wawrinka only increased his hold on the match more after each set. Wawrinka won 88 percent of his first-serve points and punched his ticket into the semifinals.
He will face the winner of the Novak Djokovic-Mikhail Youzhny quarterfinals match later on Thursday night.
Looking Ahead to Djokovic-Youzhny
The women's draw has the night off, so the two men's quarterfinals matches are at the center of the tennis universe on the 11th day of the U.S. Open.
No. 1 seed Djokovic hasn't had much difficulty in any match to this point. He hasn't dropped a set and has lost more than three games in a set just once. He has faced the No. 21 seeded Youzhny eight times in their careers.
Youzhny has had some success winning three of those matches. The last time he topped Djokovic was in 2010 in Rotterdam on an indoor hard surface. In fact, all three of Youzhny's wins over Djokovic have come on similar surfaces.
The outdoor hard courts play differently and Djokovic has vastly improved since 2010. Those factors give him an edge in the match.
Because of the familiarity on both sides, this should be Djokovic's toughest test of the tournament, but if Youzhny prevails, it'll be an even bigger upset than Wawrinka's win over Murray.
