– Top-ranked women's doubles player Bethanie Mattek-Sands needs surgery after dislocating her right kneecap and rupturing her patellar tendon during a singles match at Wimbledon.

"One of the most painful injuries that I've had," the 32-year-old Rochester native said on Facebook Live on Saturday, "and I've had a few in my career."

Mattek-Sands arrived at Wimbledon bidding for a non-calendar-year Grand Slam in doubles with playing partner Lucie Safarova. The duo had won three major tournaments in a row and five overall.

Facing Sorana Cirstea in the second round of the singles draw Thursday, Mattek-Sands fell to the grass when her right knee buckled as she moved toward the net in the third set's opening game.

She immediately clutched her knee and, down on the turf, wailed loudly, imploring for someone to "Help me! Help me!"

"I'll be out for a while," she said Saturday.
