NEW YORK (Reuters) - World number one Novak Djokovic was the first man through to the quarter-finals of the U.S. Open on Monday, sweeping past Germany's Philipp Kohlschreiber 6-1 7-5 6-4.
Djokovic, who has reached the final at Flushing Meadows each of the last four years and won it all in 2011, has been in storming form, giving every indication that the big Serb plans to be playing for the title again on Sept. 8.
