(AP) Top-seeded Novak Djokovic won the last 13 games to rout Marcel Granollers 6-3, 6-0, 6-0 in just 79 minutes Tuesday and reach his 18th consecutive Grand Slam quarterfinal.
The 43rd-ranked Granollers was coming off three straight five-set matches at the U.S. Open. Djokovic, the 2011 champion, won the first 25 points on his serve and didn't face a break point until the final game.
He'll again meet a player coming off a five-setter. Mikhail Youzhny, seeded 21st, outlasted Lleyton Hewitt 6-3, 3-6, 6-7 (3), 6-4, 7-5 earlier Tuesday.
On Sunday night, Granollers had needed nearly 3 hours to beat American Tim Smyczek 6-4, 4-6, 0-6, 6-3, 7-5 to reach his first U.S. Open fourth round.
