NEW YORK - World number one Novak Djokovic raced into the US Open quarter-finals, where he will face explosive Russian Mikhail Youzhny, who staged two stunning comebacks yesterday to beat 2001 champion Lleyton Hewitt.
Top seeded Djokovic, the 2011 champion, wrapped up a place in his 18th successive Grand Slam quarter-final when he crushed Spanish world number 43 Marcel Granollers, 6-3 6-0 6-0 in just 79 minutes.
Russian 21st seed Youzhny, a semi-finalist in 2006 and 2010, carved out a four-hour, 6-3 3-6 6-7 (3-7) 6-4 7-5 win over Hewitt after trailing 4-1 in the fourth set and 5-2 in the fifth.
Djokovic, bidding to make the final for a fourth successive year, hit 34 winners and faced just one break point against Granollers, one of four Spaniards in the last 16.
But Granollers' challenge had already been fatally undermined by having played three five-set matches and spending almost 10 hours on court, twice as long as Djokovic, who has yet to lose a set.
"I definitely played one of the best matches that I've played in my life here at the Arthur Ashe Stadium," Djokovic said after winning the last 15 games of the one-sided tie.
"It was 3-all in the first set and then I managed to get the right advantage and I played flawless tennis."
He also won the first 25 points in a row on his serve to start the match.
