PARIS — Rafael Nadal’s French Open set streak is over. His pursuit of a record-breaking 21st Grand Slam title — including 14 at Roland Garros — remains very much intact.

Nadal shrugged off dropping a set in Paris for the first time in two years and regained control Wednesday, whipping violent forehands punctuated with first pumps and yells of “Vamos!” en route to a 6-3, 4-6, 6-4, 6-0 victory over 10th-seeded Diego Schwartzman to reach the semifinals at the clay-court major tournament.

After he ceded the second set and trailed 4-3 in the third, Nadal said later matter-of-factly, “That was the moment to make it happen.”

As if wanting something were enough to will it into existence, he won the next nine games. How? Let him tell you.

“Not many mistakes,” Nadal said. “Hitting a lot of winners. Starting to hit the forehand down the line. Playing more angles. Playing longer with my forehand cross. Returning a little bit better. I mean, my serve, I think, started to work better.”

The No. 3 seed Nadal will play in Friday’s semifinals against Novak Djokovic.
