Belgium's Kim Clijsters fell Wednesday to 18-year-old Laura Robson at the 2012 U.S. Open, ending the four-time Grand Slam champion's career. Great Britain's Robson upset the 29-year-old in straight sets 6-7 (4), 6-7 (5) at Arthur Ashe Stadium.
The No. 23 seed at the tournament, Clijsters told CBS Sports that the second-round loss wasn't the way she wanted to end her career.
"This completely feels like the perfect place to retire," Clijsters said immediately after the match. "I just wish it wasn't today."
Three of Clijsters's four Grand Slam wins came at the U.S. Open. She won the 2005 event before having a daughter in 2008. She returned in 2009 to again win the event, repeated in 2010 in New York and last won a Grand Slam at the 2011 Australian Open.
Clijsters's career ends with 41 singles wins in the WTA tour and 11 more in doubles.
