Kei Nishikori became the first Japanese man in 75 years to reach the French Open's fourth round, doing so with a victory where his opponent was docked a point for being coached.
The 13th-seeded Nishikori beat No. 24 Benoit Paire of France 6-3, 6-7 (3), 6-4, 6-1 Saturday.
Paire had a set point while leading 5-4 in the second and Nishikori serving at 30-40. But Paire was given a point penalty by chair umpire Enric Molina for coaching, which is not allowed at Grand Slam tournaments.
Paire wound up winning that set, anway, but was broken in the last game of the third when he missed a drop shot.
Japan's Fumiteru Nakano lost in the fourth round in Paris in 1938.
