Andy Murray was relieved to get through another tough encounter at the start of his French Open campaign as he came from behind to beat Mathias Bourgue.

The second seed was taken to five sets in his opening match with Radek Stepanek, and he needed to go the distance again on Wednesday to reach round three.

Bourgue belied his world ranking of 164 to open up a 2-1 lead over the two-time grand slam winner, but Murray quickly shut the door and battled to a 6-2 2-6 4-6 6-2 6-3 win.

"It was a pretty stressful couple of days," he told his post-match media conference. "You know, coming back the next day and playing, it's not easy.

"It wasn't as tense as my match against Radek. Today certainly wasn't easy, I lost my way on the court for quite a while.

"So to turn it around and find a way to win after a period where I was struggling to win points [is pleasing], I was losing a lot of games to love. It was a big struggle, but I managed to get the win."

Murray will now have a rest day before meeting Ivo Karlovic in the third round, something he hopes can help him recover in time after his early exertions in Paris.

He added: "I think maybe once I have started a slam playing two five-set matches in the first couple of rounds.

"The positive is I play Karlovic in the next round, and physically, you know, the average rally length will only be a few shots, maybe three, four shots max. So that's a positive there.

"You know, for sure, tomorrow I will be tired. At least I get a day's rest now. But, yeah, you can't continue playing matches like that and then expect to win the tournament."
