Meanwhile, former French Open champions Roger Federer and Stan Wawrinka have resumed a tight battle on Court Suzanne Lenglen. Until last week, that 2015 match was also the last time Federer played in the clay-court Grand Slam tournament, having missed the 2016 edition to rest a sore back, then skipping the clay season altogether the following two years.
Nishikori was thrashed 6-1, 6-1, 6-3 by Nadal at Roland Garros, the eighth time in his career that he has fallen in the quarter-finals of a major.

"It's a huge pleasure to come back to Roland Garros", Federer said after his victory against Wawrinka.
The quarterfinals clash was by far the most pressure the world No. 3 had experienced in this French Open, the first time Federer had dropped a set and the first time he'd had to pull such a variety of tools from his belt. David Goffin was his first genuine threat, and the Belgian became the only opponent to take a set off him so far. Shortly after play was suspended, a real storm arrived. We should be able to get around [1.90] on Federer -4.5 games in the run-up to the match, and this is today's recommendation.
Leading 6-1, 6-1, 4-2 against Kei Nishikori on Court Philippe Chatrier, Nadal shook his head in disbelief when tournament organisers took the decision to stop play at the clay-court Grand Slam because a thunderstorm was on its way.
That turned out to be a tad complicated.
Federer failed to convert another five break points before gloom and rain led to the covers coming out, but he pounced on Wawrinka's second serve to move one game away from the victory. And then, finally, on his third match point, Federer closed it out with a volley, then hugged Wawrinka at the net.
Paire, the world number 38 who was trying to make the quarter-final of a Slam for the first time, was eventually undone by 15 double faults and 79 unforced errors.
The quarterfinals on the other half of the men's draw are Wednesday: No. 1 Novak Djokovic vs. That will change now: He faces No. 5 Alexander Zverev for a spot in the semifinals.
Thiem advanced by eliminating the last Frenchman in the field, No. 14 Gael Monfils, 6-4, 6-4, 6-2.
However, he won their only meeting on clay in the Italian Open final in 2017 in straight sets and beat him in the ATP Finals later that year.
"I wish I could finish in three sets", said Nishikori, whose lifetime combined record against Nadal, Djokovic and Federer now stands at just seven wins against 34 defeats.
She will next play either unseeded teen Marketa Vondrousova or No. 31 Petra Martic.
"I don't mind cruising along, to be honest", he said with a smile. "I'm always going to have a shot", Konta said. "I don't think any player on tour can go on court against me and feel like they've definitely got it".
