Andy Murray makes winning return in first match since US Open triumph
• Scot begins Japan Open title defence by beating Ivo Karlovic
• World No3 withstood 17 aces in 7-6, 6-4 victory
If Andy Murray was looking for a gentle return to top-flight tennis after winning the US Open, the Tokyo seaside took a while to oblige. The Scot struggled to find his rhythm in the opening set of his first-round match against Ivo Karlovic at the Japan Open on Tuesday , but eventually found his form to secure a solid, if unspectacular 7-6, 6-4 victory.
Murray had had to contend with last-minute complications following the withdrawal of Gaël Monfils with an injury to his right knee. The absence of the Frenchman, a former world No7 who has caused Murray problems in the past, presented an opportunity for Karlovic, a lucky loser from qualifying, to avenge his defeat by the Scot in the second round at Wimbledon this summer.
Murray must have been grateful that the humidity that blanketed the Japanese capital after its brush with Typhoon Jelawat on Sunday had given way to a comfortable pleasant breeze when he stepped on to centre court at Ariake Coliseum.
But in his first appearance since he broke Britain's 76-year men's grand slam drought against Novak Djokovic at Flushing Meadows in September, he initially struggled to deal with Karlovic's serve, and failed to capitalise on break points in the first and seventh games of the set.
"Playing against him you know it is going to be uncomfortable," Murray said after looking a little tired at times defeating the 6ft 10in Croat. "He is a tricky player.
"Mentally I feel OK. It's always hard coming into your first match after a few weeks of not playing, and my opponent made it tougher still. But I came back [into the match] when I needed to. I'm pleased with how I feel physically, even if my body might be a little bit stiff."
The latter stages of the first set had failed to produce anything approaching a rally as both players doggedly held serve. The crowd, perhaps still recuperating after Japan's new men's singles hope, Kei Nishikori had beaten his compatriot Go Soeda in three sets in the previous match on centre court, summoned polite applause, but little in the way of encouragement.
Murray, though, galvanised by the perceived injustice of a couple of questionable line calls, discovered a serve of a length and pace that began to trouble his opponent. Still, Karlovic came close to trading in his lucky-loser status for one as deserved winner with a string of aces, although Murray responded in kind with three consecutive aces in the eighth game to level at 4-4.
Murray's frustration occasionally bubbled to the surface, and a weak return into the net produced the world No3's first audible self-admonishment. The tiebreaker looked to be slipping away at 7-6 to Karlovic. Encouraged by the crowd, Murray saved a set point and then completed his comeback with a passing forehand down the line that revived memories of him at his scintillating best in the summer.
Tokyo, after all, was the world's first opportunity to examine Murray's physical state after a three-week break following his US Open triumph, and gauge any effect the end of his hunt for a grand slam title had had on his mental game.
The 25-year-old conceded his recent success had brought with it a different kind of expectation in Tokyo. "Maybe there is a bit more pressure," Murray said. "During the year there have been certain matches in which I haven't done myself justice, so I felt after the US Open that it was time to reset some goals.
"I don't want to say I was obsessed with grand slams, but winning one was so important that I was always looking ahead and bolting on to the next grand slam. Now I hope I can concentrate better throughout the year and not take my eye off the ball in any of the tournaments I play in."
With a difficult first opponent dispatched, he will test that new approach again on Wednesday as he continues his defence of the title he won last year against the Slovakian, Lukas Lacko, in the second round.
Although Murray did receive treatment on his back and took a short medical break at the end of the first set, he insisted it was nothing more than a twinge. "My back jarred a little bit, but it can happen when you start playing matches again after some time off," he said. "I took a time-out at the end of the first set but it felt fine by the middle of the second set."
That second set had begun in much the same way as the first, with both players holding serve until the tenth game. Murray, though, had returned to the court not just with a fresh shirt, but also with a renewed purpose.
Having withstood 17 aces, he ended Karlovic's resistance when he found himself with three match points. Karlovic rescued two of them, but sent a forehand long to give the Scot a more comfortable victory than had seemed possible barely half an hour before.http://www.guardian.co.uk/sport/2012/oct/02/andy-murray-japan-us-open
