Will US Open success take Robson even higher?
Laura Robson has matured as a tennis player before our eyes over the past few days here in New York.
Greats of the game such as Chris Evert, Billie Jean King and Lindsay Davenport were all saying the same thing: here is a player with a big future in the game and the potential to be a future Grand Slam winner. They should know.
Having sat by the side of Court Four here at Flushing Meadows in recent years and seen Robson blow commanding leads in the final round of qualifying, heartbreaking to witness at close hand, it's so encouraging to see the development in her game.
We mustn't forget that the British teenager is still only 18.

That Wimbledon Junior title, which flagged up her enormous promise, came at 14. The New York qualifying disappointments came at 15 and 16. Injuries have got in the way of her physical training, but her development has been gradual and effective.
The silver medal Olympic experience appears to have helped with confidence, just as the hiring of new coach Zelko Krajan, formerly with Dinara Safina and Dominika Cibulkova, has focused the winning mentality.
Staying free from injury has been a key factor, allowing her to concentrate on definite improvements to her game.
There's never been a concern about Robson's ball-striking - for a couple of years she's been one of the cleanest hitters on the tour - and this week in New York her groundstrokes were more consistently accurate than before, her returns more intelligent.
But the big improvement has been with her movement, especially side to side across the baseline, in and out of the corners. This has caught the eye of many of the wisest observers of the game, including BBC Radio 5 live pundit Nick Bolletieri.
"She's getting to more balls in the corners," says the former coach of Andre Agassi, Monica Seles and Jim Courier. "Now imagine if that picks up another notch and when she gets to those balls she can come up with an offensive shot."
Bolletieri said Richard Williams, father of Venus and Serena, had one of the best bits of advice for aspiring players. According to Bollitieri, Williams told his daughters to "run for every ball". When they asked if they should chase balls even when they are out, he responded: "Don't ever say that. Every ball is in."
Bollitieri adds: "You have two sets of eyes - your eyes and your brains. When they work simultaneously, your feet and body move without thought. Whenever you think whether or not you can get a ball, forget about it.
"That's why I believe that quality practice is better than quantity practice. Move your feet for every ball, especially when you hit that slap forehand that's going to bring defensive balls back. If you can't get there and climb on top of it, what's the point in hitting it?
"Laura, you never stopping learning baby."
And there are few better to learn from than the Florida octogenarian. He was so impressed by the way she saved eight match points against Sam Stosur, chasing down balls on which perhaps she would have given up 12 months earlier. That individual heart and desire is something even his renowned academy can't coach.
But he's tweaked a few serves and spots room for improvement with Robson. "She's got to put a little more action on her second serve," he says. "She's got a good slice serve. Now she's got to put a little junk on it once in a while so it quivers in the air."
He flutters his hand around as he says that, and smiles with genuine excitement about what the future may hold for the British number two.
After a brief break at home in London, Robson - who won many new fans in America with her smile and personality as much as her game - will head off for a tour of Asia, with two tournaments in China then two in Japan.
With a new world ranking in the mid-70s, she has a terrific chance to push on over the final few months of the season and further develop the skills she mastered in America.
The challenge will be to forget about her previous life as a player ranked outside 100, playing second-tier tournaments and scrapping around for wins here and there.
Back-to-back victories over Grand Slam winners Kim Clijsters and Li Na, as well as that very decent challenge against defending champion Stosur, have proved that Robson belongs at a world-class level.
