Top-seeded Roger Federer played his first match in more than a month on Thursday and advanced to the Mercedes Cup quarterfinals with a 6-4, 5-7, 6-4 victory over American teenager Taylor Fritz in Stuttgart, Germany.
The 34-year-old Federer, who missed the French Open with a back injury, was able to fight past the 18-year-old Fritz in a grass-court match that started Wednesday and was delayed by rain.
"It was very difficult, just as I knew before the match," Federer said. "I was more fortunate at the end.
