But Jack Sock, at the age of 20, is into the third round. This shouldn't be terribly surprising.
You could see the kid they call "J-Sizzle" coming from a few thousand miles away. With the backward hat, the Nebraska heritage and that natural charisma, it's clear that Sock aches to follow his idol, Andy Roddick, all the way to the top.
Here's his chance to take the next step.
Sock took down Maximo Gonzalez of Argentina Thursday 7-6 (3), 1-6, 7-5, 6-2 and next up is No. 18 seed Janko Tipsarevic. Gonzalez eliminated injured Wimbledon semifinalist Jerzy Janowicz in the first round.
In three US Open main draws, Sock has already fashioned an unlikely 5-2 record. Two years ago, he split two matches, losing to Roddick in the second round. Last year it was a third-round appearance. If you're following along at home, the fourth round (and a date with No. 4 seed David Ferrer) would be a logical destination.
Sock won the USTA nationals as a junior in high school, finished his career at Blue Valley High School (Kansas) with an 80-0 record, then won the USTA boys' 18s nationals and the US Open junior title in 2010.
Don't say you weren't warned.
Federer summons Evans
When you are The King, you can command virtually any performance.
Wednesday, when Roger Federer was scrambling for a practice partner through four hours of rain delays, his two coaches -- Severin Luthi and Paul Annacone -- reached out to a 23-year-old British qualifier. Was it surprising that Daniel Evans agreed to hit with the 17-time Grand Slam champion?
No, but it might have been a mistake for the guy ranked No. 179 in the world.
For after Federer defeated Carlos Berlocq 6-3, 6-2, 6-1 and Evans surprised Bernard Tomic -- seen by some as a future Federer -- by a score of 1-6, 6-3, 7-6 (4), 6-3, they were each match away from meeting in the fourth round.
"It was the first time I really got to meet him or play with him," Federer reported. "Now I have an idea how he plays, which I guess is not a bad thing.
"But at the end of the day, I think we were really just trying to help each other out on a rainy day trying to get a hit in. I thought he played really nice; got a great shot. Still a little bit surprised he beat Tomic, because we know what Bernard can do. But great effort for him."
The five-time US Open champion is now a smashing 66-8 here -- the best record of the Open era. Federer hasn't dropped a set as he goes into his third-round match against Adrian Mannarino, who was a 7-6 (4), 7-6 (5), 6-7 (5), 6-4 winner over the No. 26-seeded Querrey.
Evans now has some extra motivation to win his third-round match over Tommy Robredo.
"Yeah," said Evans. "Like if I said to any of you guys that I play Federer in the fourth round, you would have laughed at me, so I'm not going to say that. It was amazing actually to sort of hit with someone so good. Actually had a really good hit."
