Andy Murray hit the headlines for the first time at Flushing Meadows last year when he won the US Open boy's singles title.
He has since backed up his early promise and stands on the verge of breaking into the world's top 100.
BBC Sport looks at how the young Scot battled his way towards the big time.
US OPEN, BOY'S FINAL (September 12, 2004) World ranking 479
He may have already reached the heights of being world junior number two, but few outside the tennis world know who Andy Murray is when he arrives in New York.
Two weeks later he is greeted by a press throng on his return to Heathrow after beating Sergiy Stakhovsky to become the first British winner of the boys' singles.
"This is my favourite tournament and I would love to come back and win here as a senior," he says afterwards. "My long-term aim is to make the world's top 10."
David Felgate, performance director for the Lawn Tennis Association, adds: "Andy has a great future ahead of him starting in a couple of weeks with our Davis Cup away tie against Austria.
"Who knows what can happen from here."
DAVIS CUP (September 26, 2004) World ranking 410
Murray is part of the GB Davis Cup squad that plays Austria but is not called upon to play as Jeremy Bates' team go down 3-2.
SUPERSET (October 3, 2004) World ranking 413
Murray replaces the injured Tim Henman at the one-off event at Wembley Arena, and faces John McEnroe in the first round.
The American legend storms the net at every opportunity and races to a 6-1 win in just 24 minutes, before offering his coaching services - not for the last time.
"Murray is the type of player I hope I will be involved with because I think he has the potential to be a good player," says McEnroe.
PONTEVEDRA FUTURES (December 19, 2004) World ranking 533
Murray beats Nicolas Tourte to finish his year with a second Futures title in seven days and his fourth of the year.
He ends 2004 with a world ranking of 411.
DAVIS CUP (March 5, 2005) World ranking 418
Murray takes another huge leap forward when he is called upon to play the vital doubles rubber against Israel alongside fellow rookie David Sherwood.
The pair are up against the experienced Jonathan Erlich and Andy Ram, and few give the Brits much of a chance.
But Murray, who is the country's youngest ever Davis Cup player at 17 years 293 days, stars as they come through in four sets to put GB on the path to victory.
Bates says: "In terms of my Davis Cup experiences, it beats them all. For two guys making their Davis Cup debuts they were inspirational doubles players out there."
BARCELONA OPEN (April 19, 2005) World ranking 397
Murray plays his first-ever match on the main ATP Tour and goes down 3-6 6-4 6-4 to world number 79 Jan Hernych.
"I've got a very good chance to get to the top, as I'm only 17 and this guy was about 75 in the world," says Murray.
QUEEN'S (June 9, 2005) World ranking 312
Murray is handed a wild card on his return home and takes advantage with his first ATP Tour win, thrashing Santiago Ventura 6-1 6-2.
He follows that up with an even more impressive win over Taylor Dent before succumbing in three dramatic sets to Thomas Johansson.
Fitness looks to be the problem as Murray collapses through cramp in the final set.
"I played a pretty good match but I'm a bit annoyed I wasn't able to finish it," he says afterwards.
Johansson admits: "I'm very impressed with the way he's playing and he's going to get even better."
WIMBLEDON (June 25, 2005) World ranking 312
If his exploits at Queen's alert the public that there is life beyond Henman, the annual circus that is Wimbledon propels wild-card Murray to a whole new level of fame.
With Henman making an early exit the focus of the home support shifts to the young Scot, and he does not disappoint.
George Bastl is despatched in the first round before Murray beats 14th seed Radek Stepanek in straight sets for the biggest win of his career.
And a place in the last 16 looks on the cards when Murray leads former finalist David Nalbandian by two sets, before the fitness problem returns and the Argentine edges through.
"I couldn't move towards the end," says Murray. "I was annoyed I couldn't keep going in the fifth set"
Nalbandian says: "He lost because of physical problems but he has plenty of time to work on his fitness."
The end of the fortnight sees Murray move up to 213 in the rankings, and he confirms that Mark Petchey will be his full-time coach.
"He has helped me massively over the last few weeks," says Murray.
BINGHAMTON (August 14, 2005) World ranking 145
Any fears that Murray will follow so many other British hopefuls by disappearing after a promising Wimbledon are unfounded.
A wild card into Newport sees him beat Gregory Carraz in the first round before he rolls through five matches without dropping a set the next week for his first Challenger title in Aptos, California.
That prompts a wild card into Indianapolis and a win over Jesse Witten, before a highly impressive three-set defeat to Mardy Fish.
Two Challenger quarter-finals follow before another title in Binghamton rounds off an excellent four weeks.
"I think I'm ready," said Murray. "Maybe physically I'm not in as good shape as a lot of the guys inside the top 100 but I think my tennis is there."
CINCINNATI MASTERS (August 17, 2005) World ranking 132
Recent form sees Murray handed a wild card into his first Masters Series event and he makes full use of his opportunity.
Taylor Dent is again the man to suffer, going down in two tie-breaks to the Briton in the first round.
That hands Murray a dream clash with world number four Marat Safin and, despite not playing his best, he takes the second set 6-1 before losing in three.
Afterwards he admits: "I'm still not in the top 100. It's only my sixth ATP tournament. When I walked into the dressing room the first time I got here, it didn't quite feel right."
