McEnroe, Ivanisevic tip Murray for the final

Top seed and world No. 1 Andy Murray and No. 3 Stan Wawrinka advanced to a semifinal showdown on Friday, with a chance to play for the Roland Garros title on Sunday.

Wawrinka has not dropped a set on his way to the semis, and his 6-3, 6-3, 6-1 win on Wednesday over Marin Cilic was every bit as impressive as it sounds.

It is a repeat of last year's semi-final, which Murray won in four sets before going on to lose in the final.

While Murray won his last two matches in straight sets, injuries are hampering and slowing him down, so it always feels as if he's moments away from going off the boil.

"Well, I try to take couple days off, because I have some issues with my body right now", the 27-year-old said.

Andy Murray has reached the French Open semi-finals with a hard-fought victory over Kei Nishikori.

Serving at 1-1, deuce in the second set Murray was bizarrely given a time violation warning by umpire Carlos Ramos after he had let an errant ball toss land - prompting an exchange of views between the pair.

He can also be extremely resilient as he showed in almost beating Murray from two sets down in Davis Cup last March and especially in his quarter-final victory over the Scot at the US Open nine months ago.

"Obviously for a couple of points after that I was sacked up, because I was frustrated at that moment", he said.

The Romanian will play Karolina Pliskova in the last four after the world No3 dispatched Caroline Garcia 7-6 (7-3), 6-4 in yesterday's other last-eight tie.

"I think he's probably a bit less confident".

The Brit now holds an 8-2 head-to-head record against his Japanese counterpart, although they have faced off only once against each other on clay - with Murray triumphing in Madrid in 2015.

"I don't see Nishikori beating Andy".

"I think he's been great".

That first win was against Andrey Kuznetsov, and further victories have followed against Martin Klizan, Juan Martin del Potro, Karen Khachanov and Kei Nishikori. "Tennis-wise, yes, but it's not only hitting the balls". I think I'm playing better than previous year, also. Obviously it was quite windy today so timing was a little bit hard but once I started to get in a better rhythm I was able to keep him a bit further away from the baseline and that made a big difference.

Murray quickly levelled the match but after twice breaking in the third set, at 2-2 and 5-5, he handed the advantage straight back and needed a tiebreak to forge ahead.

"I lost my mind, after 6-0 down I knew I had to change something", said Nishikori.

Mattek-Sands and Safarova are looking for their third straight Grand Slam title after winning the US Open a year ago and the Australian Open in January.
