Djokovic getting in the groove

David Ferrer battled his way past Lleyton Hewitt to reach the fourth round of the US Open on Sunday while defending champion Novak Djokovic continued his New York stroll.

The second seed has looked in fine form at Flushing Meadows and he needed only an hour and 37 minutes to defeat Frenchman Julien Benneteau 6-3 6-2 6-2.

Benneteau is the 31st seed and the man who almost beat Roger Federer at Wimbledon this year but he could do nothing to threaten Djokovic.
