Andy Murray's 2020 French Open campaign was brought to a very quick and abrupt end by Stanislas Wawrinka, who won through in straight sets very easily in Paris.

Murray was simply unable to compete with the Swiss star in a very underwhelming and disappointing match on Philippe Chatrier as the two Grand Slam winners produced a one-sided match.

For the Brit it was a sluggish display in wretched conditions at Roland Garros, and he lost in one hour and 37 minutes.

Murray never looked like challenging his opponent on the red dirt, which had become sodden through a brutal opening day of rain and cold conditions.

Things did not go well for the 33-year-old from the outset and he was given a time violation for not even leaving his chair fast enough for the opening game.

From there, it was one-way traffic as Murray mustered just a single game from the opening set.

Murray landed only 36 per cent of his first serves and struggled throughout the contest in Paris in very tricky conditions in the cold and wet.

"I need to understand why the performance was like that," Murray said.

“I need to have a long hard think about it. It's not the sort of match I would just brush aside and not think about it.”

"That's just not good enough, really, against anyone, and especially someone as good as Stan."

The 35-year-old Wawrinka hit a hugely impressive 42 winners to Murray's 10 as he demonstrated his class on the Paris clay yet again.

Wawrinka won with consummate ease as he lost just five further games in the final two sets, and the 16th seed was never truly troubled.

The Swiss will next take on Dominik Koepfer of Germany in the second round in Paris.

It was not a good day for British tennis as Dan Evans was defeated in a tense five-setter by Kei Nishikori before having a pop at the balls used at Roland Garros and Johanna Konta lost to Cori Gauff in straight sets.
