American Sam Querrey couldn't build on his upset of Novak Djokovic in his next Grand Slam.
The 29th-seeded Querrey lost to Janko Tipsarevic 7-6 (4), 6-7 (0), 6-3, 6-3 in the first round of the U.S. Open on Tuesday. It was a tough opening matchup for Querrey - Tipsarevic is a former top-10 player whose ranking is down to 250th after a series of injuries. A two-time quarterfinalist at Flushing Meadows, Tipsarevic got in on a protected ranking.
He'd lost five straight Grand Slam matches dating to the 2013 U.S. Open before Tuesday.
Querrey stunned the top-ranked Djokovic in the third round at Wimbledon en route to his first major quarterfinal. But in six of his past eight Grand Slams, he's lost to a lower-ranked opponent in the first round.
He's also dropped seven of his past eight meetings with Serbian opponents - the only win that upset of Djokovic at Wimbledon.

Samantha Stosur has advanced to the second round of the U.S. Open with a 7-5, 6-7 (4), 6-1 win over Camila Giorgi.

Giorgi capitalized on only 3 of 14 break-point opportunities. She won 15 of 20 net points, but finished with 45 unforced errors.
Stosur will next face Zhang Shuai, who defeated Ellen Perez 6-1, 6-1.

The sixth-seeded Nishikori reached his first Grand Slam final at the U.S. Open two years ago, losing to Marin Cilic at that stage. But he exited in the first round in 2011, 2013 and 2015.
