NEW YORK (AP) — Men’s No. 1 seed Rafael Nadal came back from down a break in the second set to beat Viktor Troicki of Serbia 6-4, 6-3, 6-0. His next opponent will be American Sam Querrey, who reached the fourth round of a grand slam for the first time with a 7-6 (5), 7-6 (5), 6-2 victory over No. 14 seed Ivo Karlovic of Croatia.

The 20-year-old Querrey came into the year with two goals: win an ATP tournament and raise his ranking into the 30s.

He accomplished both, winning in Las Vegas in March and climbing to No. 38 in May. Currently ranked 55th, his next goal is to end the year at No. 32 or better so he’ll be seeded at the Australian Open.

The 6-foot-6 (198 centimeters) Querrey is considered the tall guy with the big serve against most opponents, but not the 6-10 Karlovic. In his second-round match, Karlovic led Florent Serra in the aces department 42-0.

This time, Karlovic only edged Querrey 24-20 and struggled to win points against Querrey’s serve. Karlovic managed just three break points and didn’t convert any.

“If I can get my racket on the ball, it’s not too bad,” Querrey said of Karlovic’s serve. “I’m a tall guy, as well. It’s up near my shoulders, where other guys it’s toward their head. … Against a guy like him, there’s a sense of urgency to every point, especially when he’s serving.”

Querrey was hardly the only man to author a surprise Saturday, capped by Mardy Fish’s 6-3, 6-3, 7-6 (4) victory over No. 9 Blake in an all-American match at night. Fish took the last five points to earn his first berth in the fourth round at the U.S. Open. Fish now meets French Open semifinalist Gael Monfils, who beat No. 7 David Nalbandian in straight sets, then showed off some club-worthy dance moves to mark a victory he called “gorgeous.”
