Querrey holds the distinction of being the only active American to reach multiple Grand Slam quarterfinals. John Isner is the only other active American to play in a Grand Slam quarterfinal, which he did at the 2011 U.S. Open.


“I mean, American tennis isn’t that bad,” said Querrey, offering a smile. “I know it kind of gets a bad rep. That’s just ’cause guys don’t win majors. We got four guys in the top 30 (No. 18 Jack Sock, No. 21 Isner, Querrey, and just outside at No. 31 Steve Johnson), a great group of young guys.


“To be in the semis is great,” he added. “Hopefully myself and the other guys up there can have more weeks like this. Hopefully, American tennis will get a little boost from this, maybe, and other guys will gain some confidence, and we can just have more and more guys go deeper in Slams.”


Querrey was one of those young players who was singled out as a potential American star almost from the moment he turned down a Southern California scholarship to go pro. He chose the pros instead of college with his banker father Mike’s blessing — dad was drafted by the Detroit Tigers, but instead went to the University of Arizona, and didn’t want Sam to also have to wonder what he might’ve missed out on.


Querrey won the first Challenger-level tournament he played as a pro and high expectations followed.


While he hasn’t made it to top-10 status, he’s had a steady and satisfying career and has ranked as high as No. 17. He’s played at the ATP Tour-level since 2006 and can boast ownership of nine career titles, with the latest coming at Acapulco, where he defeated Rafael Nadal in the championship match in early March.


In 2013, Querrey had a particularly difficult season when his engagement fell apart. Still looking for love in 2015, Querrey was featured in an episode of The Millionaire Matchmaker on the Bravo network. Unfortunately, Patti Stanger, the host of the show, didn’t earn her finder’s fee by discovering


Querrey’s soulmate. But not to worry, he’s in a more than two-year relationship with model Abby Dixon.


If Querrey can get by seventh seed Marin Cilic of Croatia on Friday, he would be one match away from a Grand Slam title.


But before he can even contemplate that possibility he needs to cope with the newness of being a Grand Slam semifinalist.


“This is the first time I’ve been in the situation,” he said. “I’m still pretty excited. I think it helps we get a day off tomorrow so you have a day to kind of relax, wind down, actually hit some tennis balls again before you go out on the stage and play a semifinal match.”
