Clijsters' career ends after mixed doubles loss

NEW YORK (AP) -- Now Kim Clijsters can go enjoy her retirement.

With her 4-year-old daughter cheering in the stands, four-time Grand Slam singles champion Clijsters' career ended Saturday night, when she and Bob Bryan lost their second-round mixed doubles match at the U.S. Open to Ekaterina Makarova and Bruno Soares 6-2, 3-6, 12-10.

Clijsters and Bryan saved four match points in the super-tiebreaker before Clijsters netted a return on the fifth.

Clijsters, a 29-year-old Belgian, announced months ago the U.S. Open would be her last tournament. She lost to British teen Laura Robson 7-6 (4), 7-6 (5) in singles Wednesday, snapping Clijsters' 22-match winning streak at Flushing Meadows, where she won titles in 2005, 2009 and 2010.

Clijsters and Kirsten Flipkens lost 6-3, 6-4 to Chuang Chia-jung and Zhang Shuai in the first round of women's doubles Thursday.
