Querrey to become the No. 1-ranked American

Sam Querrey's Grand Slam success has come slowly, really slowly, but he's winning the race. His semifinal run at Wimbledon was a first for the American, and now he's into the US Open quarterfinals with a demolition of Mischa Zverev on Sunday night.

Here's a look at Querrey's rise to No. 1-ranked American by the numbers:

That's how many winners Querrey struck on Sunday night against Zverev. He committed just eight unforced errors.

On Querrey's 42nd Grand Slam attempt, he finally broke through, reaching the semifinals of Wimbledon with an upset over Andy Murray.

29

Querrey's age.

"I hope I've got, whatever, five, six years left in me," Querrey said. "I wouldn't consider myself a late-bloomer. I've been decent for 10 years. I'm hoping I can kind of continue having more years like this into my 30s."

Querrey dropped just five games in his US Open fourth-round 6-2, 6-2, 6-1 win over Zverev.

"I didn't have a good feeling until I hit a couple balls in the warmup. A little nervous, first night match out there," Querrey said. "[I] had a good service game right off the bat. I think I broke first game of his serve, when he served. That just loosened me up right away. Felt great from there going forward."

Querrey leads by two in career-head-to-head matches against his quarterfinal opponent Kevin Anderson (8-6).
