If Novak Djokovic entered the French Open with plenty of question marks hanging over his form he departs Paris still searching for answers after suffering his first straight-set grand slam defeat since the 2013 Wimbledon final. The Austrian then pushed forward, taking the next two sets 6-3, 6-0 and forcing Djokovic to confront a lost set and match for the first time in the tournament.
The defeat was Djokovic's first straight-sets loss at a major in four years and comes just 12 months after he completed the career Grand Slam in Paris.
Earlier Wednesday, Nadal reached his record 10th French Open semifinal when No. 20 Pablo Carreno Busta of Spain retired from their match early in the second set because of an injured abdominal muscle he said began bothering him on a serve at 5-2 in the first. Just a pretty bad set. "This final set, of course, that's all me".
I'm very surprised - especially with the way how it ended.
"And my only goal is try to be ready to play my best, no?"
"But I am just trying to sense what is the best thing for me right now".
"So what is being said is positive, but maybe I won't be up to the challenge".
"All and all, I think it was decided in the first set", Djokovic said after the match.More news: Report suggests Russia hackers breached voting software firm

"Today was a ideal match for me, I thought I played very well from the beginning", Wawrinka told a news conference.
Facing a player he had destroyed in their previous meeting on clay last month, the former No. 1 Djokovic was routed 7-6 (5), 6-3, 6-0 by the 23-year-old Thiem.
Djokovic came to the court early to hit a little more before his match, and, while his new coach Andre Agassi was not present, the Serbian tennis star looked calm, composed and confident as he walked onto the court to face Thiem.
The 31-year-old Nadal has spent only around eight hours on court, dropping 22 games in the process, to reach his record-extending 10th semifinal at the French Open.
Djokovic's backhand really let him down in the tiebreaker: All seven points won by Thiem ended with that stroke. Murray advanced to his fourth straight semi-final in Paris, defeating Nishikori to avenge his loss to the Japanese star at the US Open past year.
"I'm playing well, I'm moving ahead", Nadal said afterward.
Wawrinka improved to 12-2 career against Cilic.
