And then there are the stars-turned-commentators — John McEnroe, Chris Evert and Martina Navratilova, who are as recognizable to young fans as they are to the older generation.

“I didn’t think I was going to be hanging around the sport as much as I am, but I also didn’t think I would still be playing on the tour when I was almost 39,” said Navratilova, a Tennis Channel analyst. “You just have this wealth of knowledge, and it’s nice to be able to share it and pass it on.”

But for most of the former stars engaged in coaching or talking tennis on television, the Grand Slam leaves little time for socializing, or even dinner outside the venues.

“There’s no time at all, with the late-night matches,” said ESPN’s Pam Shriver, who ranked as high as No. 3 in singles and won 21 Grand Slam doubles titles with Navratilova. “But I’m here to cover tennis, and I’d just as soon be working than having a meal in the city.”

As with other sports, tennis’ most decorated retired players have struggled to persevere as coaches, which requires subjugating one’s ego in deference to the contemporary star’s. But Becker did have a productive run coaching Djokovic, and Ivan Lendl was widely credited for helping Andy Murray win Wimbledon twice and the U.S. Open.
