NEW YORK (Reuters) - Sam Querrey, the last American man standing at the U.S. Open, would not be knocked off his feet as he strolled into the quarter-finals at Flushing Meadows with a 6-2 6-2 6-1 demolition of Germany’s Mischa Zverev on Sunday.

What looked an intriguing matchup of styles between the big-hitting American and Zverev, a left-handed serve-volleyer, was rendered a one-sided show for a delighted capacity crowd at Arthur Ashe Stadium.

Querrey, looking to followup his semi-final run at Wimbledon with an even better effort at Flushing Meadows, needed just 77 minutes to dismiss the German to become the first American to reach the U.S. Open quarter-finals since Andy Roddick in 2011.

It was a ruthless performance by Querrey as he bombarded Zverev with 18 aces and avenged the German’s victory over top seeded American John Isner in the third round.

Querrey stormed out of the gate breaking his 30-year-old opponent at the first opportunity and again to clinch the opening set in a lightning quick 24 minutes.
