World No. 1 Novak Djokovic and Serena Williams ruled supreme on Tuesday, sending ominous warnings to their rivals with dazzling, runaway victories over Spanish opponents at the US Open.
Djokovic said he played some of his best tennis on the Arthur Ashe Stadium court in trouncing Marcel Granollers 6-3, 6-0, 6-0, and Williams could not have done better, handing Carla Suarez Navarro a 6-0, 6-0 beating at the National Tennis Center.
Djokovic said his game was clicking just as planned.
"Today, the second and third set have been some of the best tennis that I've played on Arthur Ashe in my career," said Djokovic, who won the title in 2011 and was a finalist last year and in 2007.
"I was wishing to be more aggressive as the tournament progresses," added the Serb, who won the first 25 points on his serve and 28 of 30 points he contested at the net.
Djokovic moved into the quarterfinals against Russia's Mikhail Youzhny, who ended the magical run of 2001 US Open winner Lleyton Hewitt by escaping a 1-4 hole in the fourth set and a 2-5 stranglehold in the fifth.
Youzhny won 6-3, 3-6, 6-7(3), 6-4, 7-5 win. Youzhny, the 21st seed, took pride in outbattling renowned fighter Hewitt in the nearly four-hour match.
