Ready, set, go....
Reasons Shapovalov will have the best US Open result:
—Experience. They're all 19 years old, but Shapovalov has been a Top 100 player for almost a year now, having broken that barrier after his run to the Rogers Cup semifinals. Meanwhile, Tsitsipas cracked the Top 100 last October, and de Minaur just eight weeks ago.
—He's the only one of the three to have won a US Open match. Three, to be exact, as Shapovalov made it all the way to the fourth round in his US Open debut last year. De Minaur fell first round in his US Open debut last year, and Tsitsipas will be making his main draw debut this year.
Reasons Tsitsipas will have the best US Open result:
—He's the only one of the three to reach the second week of a major this year. Tsitsipas made the fourth round of a Slam for the first time at Wimbledon; de Minaur's best major finish this year was the third round of Wimbledon; Shapovalov fell in the second round of all three Slams.
—He might be a Top 16 seed by Flushing Meadows. With absolutely nothing to defend over the next two weeks—he didn't play Canada or Cincinnati last year—Tsitsipas has a chance at a Top 16 seed for the US Open, which would give him a far better draw than a Top 32 seed.
Reasons de Minaur will have the best US Open result:
—He's had the best summer of the three so far. De Minaur is the only one of the three to reach a final this summer, doing so at the 500-level event in Washington, D.C. At the French Open, the Aussie was outside the Top 100. Now he's No. 45.
—He'll still be somewhat under the radar. Unless he does something huge over the next two weeks, de Minaur is more than likely going to be unseeded at the US Open, and will be dealing with less pressure.
OUR EXPERTS WEIGH IN:
ED MCGROGAN: Tsitsipas
I'll eliminate De Minaur, who is unlikely to be seeded and could face elite competition right away. Of the other two 19-year-olds, Tsitsipas has simply been better than Shapovalov of late. The Canadian, who rode his own wave of momentum into the fourth round last year, has more US Open experience, but I think the confident Greek could reach the second week.
Shapovalov is flashier, and he reached the fourth round at the Open last year. De Minaur is coming off a run to the Citi Open final. But since April, Tsitsipas has been improving each week. By the time he reaches New York, he may be due for a major breakthrough.
ASHLEY NDEBELE: Shapovalov
Playing in Toronto this week will reinvigorate Shapovalov, who kickstarted last year's run at the Rogers Cup. After upsetting Rafael Nadal and Juan Martin del Potro in Canada last summer, he reached the fourth round of the US Open. Plus, Tsitsipas and De Minaur have yet to win best-of-five-set matches in New York.
ZACH COHEN: Tsitsipas
De Minaur reached the final in D.C., but Tsitsipas is playing the better tennis overall. Both men lost to Alexander Zverev at the Citi Open, but the Greek looked impressive at Wimbledon, which followed what was great clay-court season. Tsitsipas has experience in big matches already, which will help him in New York.
STEVE FLINK: Tsitsipas
I am going with Tsitsipas. All three of these players are in form but I believe Tsitsipas has the most potential to go far at the US Open. He is ready to display his best tennis in New York. I like his mentality. Shapovalov made it to the fourth round last year at the Open and he will do very well again, but Tsitsipas has convinced me all year that he is going to be a great player. He just might be a quarterfinalist in New York.
NINA PANTIC: Shapovalov
The Canadian thrived in the buzzing atmosphere of New York last year as a qualifier. Now he returns with a full year of experience under his belt, with his first defense of sizable ranking points behind him. Despite that, he'll continue to go for broke with nothing to lose—even though there's 205 points at stake.
