Britain's Andy Murray put his injury worries behind him with a comprehensive win over qualifier Pablo Cuevas in the first round of the US Open.
Murray appeared to be back to full fitness against Cuevas
The 20-year-old needed less than two hours to outclass the Uruguayan 6-2 6-3 6-0 on the Grandstand court.
Murray did not appear to be troubled by the wrist injury which has limited him to three matches since mid-May.
The 19th seed hit 37 winners as he booked a second-round meeting with Jonas Bjorkman.
"It was great," said Murray. "It's quite hard to describe but when you don't play for such a long time at an acceptable level it's quite tough to stay positive.
I can play great tennis and I should enjoy it more
"Although it was the first round and against an opponent that a lot of people won't know, that result meant so much to me. More than a lot of results I had earlier in the year."
It had always looked like being a good draw for the Briton as he makes his way back from injury, and so it proved.
Cuevas, 21, was playing not only his first Grand Slam match but his first match of any kind at ATP Tour level.
The gap in class was apparent throughout and Murray was able to use the match to test out his wrist and all-round fitness.
In his three previous comeback matches, Murray had not had sufficient confidence in the wrist to hit his forehand at full power.
And while he rarely gave it absolutely everything on that wing against Cuevas, the Scot was clearly far more comfortable with his fitness.
"There was one point I remember - I think it was 4-2 and game point - I hit a running forehand passing shot and that was the first time I really, really hit out on my forehand 100%," he said afterwards.
"It's easy to do it in practice when the ball's straight to you but when you're on the run and it's a reaction it's completely different, and after that I was a lot more confident.
"I still need to get the average speed of my forehand up, it was a little bit slow today, but with each match I'm going to get more confidence."
Murray broke the Uruguayan's serve at the first opportunity and served for the opening set at 5-2, only to be broken himself.
But that proved to be the only hiccup of the day for Murray, with a single break in game four giving him the second set and the third flying by in just 21 minutes.
And Murray revealed later that the work he has been doing with a sports psychologist has had a significant effect.
"I think I learned to appreciate playing tennis again," said the 20-year-old. "I was getting angry on court about things that weren't really necessary.
"I was playing great tennis this year and still wasn't really that happy when I was playing. At Wimbledon in 2005 and here in 2005, my attitude and my body language was excellent.
"The last year it's not been as good, I've been showing more negative signs than I have positive, and I learned to just enjoy playing again because I missed such a big chunk of this year.
"I can play great tennis and I should enjoy it more."
