Flushing Meadows, NY (Sports Network) - World No. 1 superstar Novak Djokovic was a straight-set second-round winner Friday at the U.S. Open.
The 2011 U.S. Open champion handled German Benjamin Becker 7-6 (7-2), 6-2, 6-2 in 1 hour, 51 minutes at Ashe Stadium on the hardcourts at the USTA Billie Jean King National Tennis Center.
The six-time Grand Slam titlist Djokovic was last year's runner-up to Andy Murray and also lost in finals here in 2007 and 2010.
Defending champion Murray finished strongly and beat 81st-ranked Leonardo Mayer of Argentina 7-5, 6-1, 3-6, 6-1 to reach the U.S. Open's third round.
After dropping the third set, then opening the fourth 1-all, the No. 3-seeded Murray powered his way to the last five games on Friday.
It's his 26th consecutive victory in a second-round Grand Slam match. Murray's last loss at that stage came in his U.S. Open debut in 2005.
Last year in New York, Murray became the first British man since 1936 to win a major tournament, snapping an 0-4 mark in Grand Slam finals. He added a second major trophy at Wimbledon last month.
Mayer is 0-12 against top 10 opponents.
Djokovic is the reigning Australian Open champ and was last month's runner-up to Murray at Wimbledon. His third-round opponent will be unheralded Portuguese Joao Sousa.
Lleyton Hewitt pulled off a shock five-set victory over Juan Martin del Potro.
Hewitt won 6-4, 5-7, 3-6, 7-6 (2), 6-1 in a second-round match between two former U.S. Open champions which lasted four hours.
The 32-year-old Australian won the U.S. Open in 2001, and Wimbledon in 2002, but has been troubled by nagging injuries more recently and is now ranked 66th.
Hewitt displayed his trademark scrambling on the baseline to stretch for passing winners against the sixth-seeded Argentine.
Hewitt next faces 102nd-ranked Evgeny Donskoy.
Fifth-seeded former Wimbledon runner-up Tomas Berdych fired 11 aces in dismissing game American Denis Kudla 7-6 (7-3), 7-6 (7-3), 6-3. The formidable Czech will battle seeded Frenchman Julien Benneteau in his next outing.
Meanwhile, resurgent 12th-seeded 35-year-old German Tommy Haas took care of Taiwan's Yen-Hsun Lu 6-3, 6-4, 7-6 (7-3). The one-time world No. 2 Haas is a three-time quarterfinalist in Flushing.
In other second-round action involving seeds, No. 21 Russian Mikhail Youzhny mauled Ukrainian Alexandr Dolgopolov 7-5, 6-1, 6-3 and a No. 31 Benneteau topped fellow Frenchman Jeremy Chardy 6-4, 6-3, 6-4. The 31-year-old Youzhny is a two-time U.S. Open semifinalist (2006, 2010) and will meet Haas in the round of 32.
Also on Friday, the aforementioned Sousa outlasted Finnish veteran Jarkko Nieminen 1-6, 6-3, 3-6, 6-3, 6-4, Spaniard Marcel Granollers held off American Rajeev Ram 3-6, 4-6, 6-2, 6-3, 7-5, and Uzbekistan's Denis Istomin drubbed German Tobias Kamke 6-4, 6-2, 6-2 at the final Grand Slam event of the year.
