Roger Federer is going home earlier than expected and isn't part of the Final Four at the Monte Carlo Masters.
Eighth-seeded Jo-Wilfried Tsonga sent the third-seeded Federer packing with a 3-6, 6-2, 7-5 victory on Friday to reach the semifinals. Tsonga will face fellow Frenchman Gael Monfils, who defeated Spain's Marcel Granollers 6-2, 6-4.
Federer, from Switzerland, was playing in his first tournament since undergoing surgery on his left knee following the Australian Open. He won the opening set before Tsonga rebounded with a strong second-set victory and then looked like he was going to advance when he needed just two points to close the match.
But Tsonga won that game to tie the set and prevailed by winning each of the last two games.
"It was good to play back-to-back, yesterday and today, good to play 2 hours, 10 (minutes) today," Federer said. "It was nice to play an intense match. I'm happy how the body reacted.
"It was unfortunate because I had my chances. But in this tournament, (it) really doesn't matter at all if I missed those chances."
Nadal is gunning for his ninth Monte Carlo title and he looked up to the task during a 6-1, 6-4 victory over Switzerland's Stan Wawrinka that lasted just 68 minutes.
This is the fifth time Nadal has reached the semifinals this season but he has yet to win a tour event.
"Stan made more mistakes than me, but at same time he was going for more on his shots all the time," Nadal told reporters. "When you want to play this way, very aggressively, you can make mistakes.
"I defended well, I moved well. When I had the opportunity, I was trying to control the point with my forehand and with my backhand, too. I am very happy with the way that I played. The important thing is to play points in a row with the right intensity, without many mistakes."
The fourth-seeded Wawrinka was unhappy with his performance against the Spainard.
"It was not a good day," Wawrinka said. "I rushed at the beginning. I wasn't able to set up my game. You pay for that when you play against Rafa."
Murray lost to Nadal in the Monte Carlo finals in 2009 and 2011. He reached the semifinals this time with a 6-2, 6-0 victory over Canada's Milos Raonic.
"I played really well today," Murray, of Scotland, said afterward. "I served better and obviously returned very well against a great server. It was one of my best matches in a while.
"Against someone with his game style you know that normally he's tough to break and that you only get a few chances during the match. You have to be very patient because you might go a few games where you're barely touching balls because he's serving big and hitting big forehands."
The 13th-seeded Monfils had to work a little to dispatch Granollers but hasn't lost a set in the tournament.
