The 16-time Grand Slam winner is the defending champion in London and is looking for a record sixth title at the season-ending event and his 70th overall.
Thursday’s win was his 37th victory overall at the ATP finals _ previously known as the Masters Cup _ surpassing Boris Becker and putting him two short of Ivan Lendl’s record.
Even at 30, though, Federer doesn’t feel pressed for time to chase even more records.
“I guess I do play for a little bit of the legacy and the history, the record books, all that stuff,” Federer said. “But it’s really the press that reminds me of most things. I just try to go along with it because I have no intentions to quit. So I can concentrate on just playing tennis at the moment.”
