About the mercurial-at-best behavior of Nick Kyrgios at, well, most events in which he competes, among some other hot-headed younger peers on the ATP Tour, Federer is measured.
"I laugh about it, because I think it's actual good, it's good that guys are showing their temper," he said. "I can relate to it ... and it's nice to see it still exists."
"I understand that people get upset, because it happens to me still in practice, I get super-frustrated as well sometimes," Federer said, perhaps alternately inspiring and disheartening his ATP fellows who might hear the podcast. "Tennis is a sport in which you will make mistakes. It just happens. I didn't want to be that kind of player, with that attitude, because I just felt so drained about midway through a tournament, getting so upset."
Steadying his in-match emotions, in a sport built on solo problem-solving, Federer has made the most of it, to the tune of 20 major singles titles. He still leads the hot-on-his-heels Rafael Nadal, who has 18, and Novak Djokovic, who owns 16 after topping Federer at Wimbledon fewer than two months ago. (Djokovic then became the first man in 71 years to win a singles final at SW19 after saving match points.)
