Andy Murray looked as though he would be exiting the French Open in the early rounds after he lost the first set to Jarko Nieminen and appeared to be struggled with his long-standing back injury.
The world number four fell 4-0 behind in the opening set and was forced to call for the trainer as he struggled to move around the court with his usual speed and elegance.
Unable to fire down his serve he eventually lost the first set 6-1 and following further treatment it seemed as though he would have to retire from the match.
However, in the second set he began to shown signs of a recovery and his movement improved. Suddenly he began to make an impression on the Nieminen serve and secure two breaks to take the second set.
In the third and fourth set Murray was back to his fluid best as he eventually secured a 1-6 6-4 6-1 6-2 victory that will see him move into the third round at Roland Garros.
"It was tough. I was obviously struggling at lot particularly at the beginning of the match. He helped out a little bit and got nervous at the end of the second set. I don't know how I won to be honest," said Murray.
"I think my back went into spasm, it was sore this morning when I got up and practiced and it was sore 20 minutes after I finished practice.The guys were telling me to stop after the first set, we talked about it briefly before the match and I just decided to play.
"Sometimes guys can get nervous and you feel better, and a combination helped me get through.
"It's not easy playing against someone that's struggling and sometimes guys stop or try finishing the match. I managed to turn it around and it was tough for him."
