Roger Federer, who has not yet dropped a set in the French Open tennis tournament, reached the semifinals on Tuesday with a victory over Gael Monfils of France.
The score was 6-4, 6-3, 7-6 (7-3) in a game lasting 154 minutes.
It was the seventh time the two players had met. Monfils has beaten Federer only once, in the Masters 1000 at Paris Bercy last year.
The win takes Federer through to the semifinals, where he will meet Novak Djokovic of Serbia.
After the match Federer said he was looking forward to the next round.
“It’ll be a great match, and the best man will win,” he said.
Although overall Federer has won 13 of the 22 matches the two have played, this year Djokovic, the world number two, has won all three of their encounters so far.
He is unbeaten this season, and if he wins in Paris, he will displace Rafael Nadal of Spain from the number one spot.
