British number one Andy Murray reached the third round of the ATP Masters 1000 event in Paris with a battling 2-6 6-4 6-3 win over David Nalbandian.
Murray was broken twice in the first set despite serving seven aces, but levelled after breaking in the final game of the second set.
A wrist problem caused alarms in the third set but he pressed on and another late break put him on the verge at 5-3 and he served out superbly to love.
Murray lost his serve in the third game and Nalbandian quickly broke again to go 4-1 up.
The 28-year-old hurried through his next service game and although Murray then held serve, it merely delayed the inevitable as another hold to love, finished off by an ace, saw Nalbandian take the set 6-2 in 33 minutes.
The second set went with serve until the 10th game when Murray forced his first break points of the match by moving to 15-40, and he took the first of them to take the set 6-4, levelling the match and leaving Nalbandian angrily slamming his racket to the ground.
Murray had treatment on the wrist - the same one he injured in 2007, missing almost four months of action - at 2-2 in the decider but then changed his shirt, an encouraging statement of his intent to continue, and held serve with the aid of his 16th ace.
He progressed well to 4-3 and forced two break points, taking the second to leave him serving for the match, which he did with the minimum of fuss.
After the match, Murray told Sky Sports 4: "It was very difficult, I had to change my game completely. I pretty much served and volleyed for the whole of the second set because I couldn't win a point from the back of the court.
"I changed my tension, sent a few rackets back to the stringer and got them at the end of the second set and it made a difference.
"It's something I need to look to do more often, I'm going to look to improve on that for next year because on a surface like this it works so well.
"I think it threw his rhythm off a little bit. At the end of the first set I needed to change something."
Murray played down the wrist injury, adding: "I hit the half-volley and felt a sharp pain up my wrist. I've had a couple of problems there in the past so I got a little bit scared.
"At the end of the match it felt okay, we'll see when I cool down."
The Dunblane star next faces big-serving Croatian Marin Cilic, and said: "It's a good court for him, it's very quick , and if he serves well it'll be a difficult match. I'll have to make a better start."
