US Open: Novak Djokovic begins title defence with easy victory

Novak Djokovic made a convincing start to the defence of his US Open crown with an effortless straight sets victory over Italy's Paolo Lorenzi.

The second seed needed just 73 minutes to beat Lorenzi 6-1 6-0 6-1.

Joining him in the second round at Flushing Meadows is fifth seed Jo-Wilfried Tsonga, who defeated Karol Beck 6-3 6-1 7-6 (7-2).

Tomas Berydch progressed with a 7-5 6-3 6-3 win over David Goffin, while Andy Roddick is also through.

Roddick, the 2003 champion and 20th seed, beat fellow American Rhyne Williams 6-3 6-4 6-4 to set up a meeting with Bernard Tomic.

Lorenzi broke Djokovic in the opening game of the match, but that was as good as it got for the 69th seed, who had to wait until the start of the third set to win his next game.

Djokovic equalled his most convincing win in a Grand Slam match, conceding only two games at a major tournament for the fifth time in his career.

Serbian Djokovic, bidding for a sixth Grand Slam title, won 79 of 114 points and hit seven aces and 32 winners.
