(AP Photo/Adam Hunger)New York • Sam Querrey was about as perfect as can be en route to becoming the first American man in the U.S. Open quarterfinals since 2011.

Querrey never faced a break point and wound up with 55 winners and only eight unforced errors while easily beating 23rd-seeded Mischa Zverev of Germany 6-2, 6-2, 6-1 on Sunday night.

“I thought I played really well. I kind of couldn’t have done anything better out there,” the 17th-seeded Querrey told the crowd in his on-court interview. “I kind of was in the zone.”
