NEW YORK Serbian world number one Novak Djokovic squashed another American hope, pounding Sam Querrey 6-3 6-2 6-2 on Saturday to reach the fourth round of the U.S. Open for the eighth straight year.
Djokovic, a finalist the last four years, winning it all in 2011, improved his record to perfect 8-0 when facing American opponents at Flushing Meadows.
Querrey's exit leaves John Isner as the last American man standing. He plays Germany's Philipp Kohlschreiber later on Saturday.
The winner of that match will take on Djokovic in the fourth round.
