Russia's Maria Kirilenko, ranked 27th in the world, defeated 2011 U.S. Open champion Samantha Stosur from Australia in second round action of the Pan Pacific Open in three sets, 6-2, 4-6, 6-4.
"You never want to go out in the first round after the week I had at the U.S. Open," Stosur said. "It's hard to explain how you could do well at the U.S. Open and then not do well here. I came as prepared as I could."
Stosur, seeded ninth at the 2011 U.S. Open, defeated the 25th seeded Kirilenko in the fourth round of the 2011 U.S. Open in their last match up, 6-2, 6-7, 6-3.
"I just played her a couple weeks ago, so I knew what to do," said Kirilenko after her win against Stosur.
