Kim Clijsters has ended Ana Ivanovic's run 6-3, 6-1 in the third round of the U.S. Open.
"I knew once I got out there that Ana is the type of player, she's playing with a lot more confidence, and if I can stay with her in the beginning of those first few games where she was playing really good tennis and kind of just, yeah, make her once in a while doubt a little bit," said Clijsters.
