Clijsters to Retire After U.S. Open

Kim Clijsters announced she will retire from tennis after the U.S. Open in September, the setting for three of her four major titles.

Clijsters retired from the game back in 2007 to give birth to her first daughter but returned in 2009 to enjoy the most successful period of her career.

The 28-year-old added to her first grand slam in 2005 by securing back-to-back titles at the U.S. Open in 2009 and 2010. She then added the 2011 Australian Open to her roll of honor.

It was during this period that Clijsters took over the world No. 1 ranking for the first time in five years, but over the last 12 months, a series of nagging injuries have cut short her time on the court.
