I think this is too good of an opportunity for Thiem to pass up.
Nadal will face either Croatian third seed Marin Cilic or Juan Martin del Potro, the fifth seeded Argentine, in the semifinals. The 32-year-old Spaniard is 84-2 for his career at the French Open, winning four consecutive titles from 2005-08, another five consecutive from 2010-14, and No. 10 a year ago.
Del Potro claimed the tiebreaker, and though he faltered late in the second set, he regained control of the match with five straight wins to claim the third.
The fourth set went hurriedly with serve until 5-5, when from out of nowhere Del Potro fashioned three break points.
Similarly, del Potro too had to wait till day 12 of the French Open to vanquish Marin Cilic in four. "Here with Federer", Del Potro said after his quarter-final victory. That said, Thiem has already been at a high level for a long time and he'll be used to this situation. "I was close to (quitting)". Nadal has won 10 of his last 11 matches on clay court.More news: Reese Witherspoon confirms 'Legally Blonde 3'
"Del Potro has achieved great victories this year". I'm not really interested by all these things, and I don't think that - you can't really know the reality of how old is your body. "That's the most important for me".
In the other women's quarterfinal, No. 1 Simona Halep takes on former No. 1 Angelique Kerber in a rematch of their epic Australian Open semifinal in January.
Halep converted her first match point when Muguruza sent a final backhand long.
His upward trajectory - rising from lower than 1,000 in the world past year to a guaranteed career high of fourth when the next round of rankings come out - looked unlikely after he missed nine Grand Slams in a row after nearly disappearing from the tour in 2014. "I'm feeling good, happy, I can't complain", he had said.
Halep is guaranteed to remain the world No. 1 after the tournament.More news: Metro promises special TJ Oshie SmarTrip card if Caps win Stanley Cup
- His nine wins over players ranked world number one is a record for players to have never been No 1 themselves. It's a little different in that aspect. "I'm just playing tennis".
Halep next faces third-seeded Garbine Muguruza.
Canada's Gabriela Dabrowski and Croatia's Mate Pavic lost their mixed doubles final at the French Open on Thursday. The second set like, the first was dominated by serve until Cilic fired himself up to break at 4-4 - a furious Del Potro throwing his racket at the changeover.
Pavic and Dabrowski were the top seed in Paris, while Chan and Dodig were seeded second.
Halep looks like the runaway favourite for Saturday's clash, although 2017 U.S. Open victor Stephens holds the advantage of having won a major and can clinch a second Grand Slam crown in nine months if she upsets the odds in Paris.More news: Liverpool agree fee for key transfer target Nabil Fekir
