Coco Gauff's time at Wimbledon is over after just one round. Gauff, the No. 2 seed who is coming off a title at Roland-Garros, lost to Dayana Yastremska 7-6 (3), 6-1 in the first round on Tuesday. Gauff is now just the third player in women's singles history to lose in the first round at Wimbledon after winning the French Open.

Matches in the men's draw are best-of-five sets, and each set must be won by two games. If the score of the match reaches 6-6, then a tiebreak game is played. In the tiebreak, the winning player is the first to reach 10 points with a two-point margin of victory.

Keys' perfect 10-0 record in the first round at Wimbledon appeared to be in serious jeopardy after upstart Elena-Gabriela Ruse snatched the first set in a tiebreak. But despite the scorching afternoon temperatures in London and an opponent who was on a heater from the baseline, Keys found enough to survive.
