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 years 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. Opens 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. Its his 26th consecutive victory in a second-round Grand Slam match. Murrays 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 months 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.

Meanwhile, resurgent 12th-seeded 35-year-old German Tommy Haas took care of Taiwans 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.

"I havent really seen anyone rehab a partially torn ligament and have success. And it seems what it does is (it) just delays the inevitable thats going to happen and instead of maybe missing a year and a little bit of time, you miss a couple of years." Nova left last Saturdays 16-1 loss at Tampa Bay in the fifth inning after allowing eight runs aand eight hits, including four homers.dddddddddddd An MRI revealed the injury and he was placed on the 15-day disabled list. He was transferred Thursday to the 60-day DL. "Obviously its difficult to go through the operation and rehab," Girardi said, "but a lot of times you come back stronger."
