Roger Federer needed four sets to make it through to the fourth round of the French Open on Friday, beating Dmitry Tursunov 7-5, 6-7 (7), 6-2, 6-4.
Federer, who had won his opening two matches in straight sets, converted only four of his 21 break-point opportunities against the 31st-seeded Russian.
Shortly after winning the second-set tiebreaker, Tursunov appeared to have a minor meltdown while trailing 2-1 in the third. He argued with the chair umpire and took a medical timeout. He left the court for several minutes, leaving Federer to practice some serves while awaiting his opponent's return.
Federer is trying to win the title at Roland Garros for the second time. He is the 2009 champion, but lost in the quarterfinals last year.
