Serena Williams, 8th in the world and looking for a 24th Grand Slam title to equal Margaret Court's record, gave up on Tuesday in the first round of Wimbledon against Belarusian Aliaksandra Sasnovich visibly injured in the right thigh.
The American, who turns 40 in September, threw in the towel at 3-3 in the first set and walked out of the court in tears.
