WIMBLEDON, England — At age 37, Serena Williams aims for her eighth Wimbledon title while Roger Federer, also 37, fixes his gaze on his ninth. Novak Djokovic (32) has designs of defending his crown. Rafael Nadal (33) has designs of backing up his French Open title. And Andy Murray—Sir Andy Murray, to us—easing his way back from near retirement on account of a hip injury, came looking for a mixed doubles partner. He settled on Serena.
And yet it is a 15-year-old ranked outside the top 100 who has stolen the day. Coco Gauff of Florida may be younger than some of the ball kids ministering to her.
