It will be the 18th time Murray has played Wawrinka, with the Briton having won both last year's meetings at the French Open and ATP Finals.
Andy Murray feels he will be up against it in the French Open semi-finals as the odd man out who arrived at Roland Garros playing "garbage".
He'll play 2015 champion Stan Wawrinka in the last four tomorrow - as he did at the same stage previous year.
"It's not always been easy for me here but the last few years have been great", Murray said courtside.
Rafael Nadal and Dominic Thiem will meet in the other last-four match after the young Austrian stunned defending champion Novak Djokovic. "Hopefully I can take advantage of that and find solutions to beat him", the Swiss said of that upcoming Friday battle of three-time Grand Slam champions.
As is often the case with Murray it required a sense of injustice to unlock his best shots and on this occasion it came courtesy of a time violation from umpire Carlos Ramos. "At the same time he was raising his level, so it was tough to play in the end". Wawrinka hopes to make his second French Open final. The 30-year-old is also set to slip out of the world's top two. I think if someone is intentionally slowing a match down, you know, they should be punished for that, but it's a rule that is going to be challenging regardless of whether there is a clock on the court or not. "Once I found a bit of rhythm I started to control things a little bit more".
"From there on in Murray went from strength to strength and yes he had his ups and downs and let Nishikori back in but Murray just kept getting fired up".
Murray's display will not give Wawrinka any sleepless nights, but he will remember how outstandingly well the world number one played to beat him in four sets in last year's semi-final. "I think my serve got a little bit bad today, missing too many first serves". "So it was important to stay strong with myself, and I'm happy to get through this match", he said.
The sixth seeds are to face unseeded Australians Ashleigh Barty and Casey Dellacqua, who completed a 6-3, 6-4 victory over Irina-Camelia Begu of Romaina and Zheng Saisai of China in 1 hour, 33 minutes. Hard question. So far when I have beaten a top guy, I have always played a way worse match the following day.
Coincidence or not, after that incident Murray was far more aggressive and began to take over.
Throughout their careers, Nadal is 4-2 against Thiem. He's great player. Very smart tennis player.
