Roger Federer hasn't forgotten his tennis roots.
The 37-year-old Swiss made history today as the only player, male or female, to contest 400 career Grand Slam singles matches.

In the aftermath of his 6-3, 6-1, 7-6 (8) sweep of Casper Ruud to reach the Roland Garros fourth round for a record 14th time, Federer credited Swiss standouts Martina Hingis, his former mixed doubles partner, Marc Rosset, his former doubles partner, Jakob Hlasek and Patty Schnyder, who "paved the way for me."
"I was lucky," Federer told the media in Paris. "I had Rosset, Hlasek, Hingis, Schnyder before me, and they showed me the way and they paved the way for me, because I come from a small country, but we have everything.
"We have a national center. We have a structure. And I think this is an advantage to come from a country like this."
Hall of Famer Hingis has, jokingly, taken some credit for teaching the young Federer how to win.
In an interview with the Times of India, Martina reveals she often reminds Roger that she taught him to win during their run to the 2001 Hopman Cup title.
"You could always see the talent. I tell him I was the one who taught him how to win titles," a smiling Hingis told the Times of India. "Before that he played a few finals but didn't win anything. Hopman Cup was his first big title and he has won a few after that, isn't it?"
In 2001, Hingis was the star attraction and Federer a rising young talent when they joined forces to lead Switzerland to the Hopman Cup championship with a win over Monica Seles and Jan-Michael Gambill in the final.
Hingis and Federer remain good friends. The Grand Slam king, who once served as a ball boy during a Hingis match, revealed he is the former No. 1's "biggest admirer."
In this International Tennis Hall of Fame video tribute to Hingis, Federer praises his former mixed doubles partner.
"I was always the biggest admirer of her," Federer says. "How, at a young age, she was able to handle the pressure and play so well. And then obviously the whole combination was just incredible."
