NEW YORK(AP) Kim Clijsters is back in the fourth round of the U.S. Open for the first time since she won the title in 2005.

Clijsters cruised to a 6-0, 6-2 victory over Kirsten Flipkens on Friday and has dropped one set in three matches in her return to Flushing Meadows.

The 26-year-old Belgian left tennis in 2007, got married and had a child. But she returned to the tour this month, and will enter the rankings after the tournament.

Clijsters had 13 winners and finished off Flipkens in 62 minutes.
