Djokovic eases into semis

There were high expectations for the a match that featured two of the most watchable players in the men's draw, and while both showcased glimpses of their crowd-pleasing shot-making, the windy conditions wreaked havoc on their play.

Routine ball tosses were blown off course, the pair's towels were at times strewn across the side of the court and serves were slowed to 110 mph (177 kph) as the gusts increased in the latter stages of the match.

"These are the worst conditions so far in this tournament," Djokovic said in a courtside interview after the match. "But I was really focused when I needed to be and I'm just so happy to come through in straight sets."

France's Monfils, cheered on by countryman and New York Red Bulls striker Thierry Henry, jumped ahead 4-2 in the opening set after breaking the number three seed's serve.

But Djokovic, who had never lost to his French opponent in four previous meetings, broke back two games later and showed beautiful variation to dominate the subsequent tiebreak 7-2.

As the wind was increasingly whipped up inside Arthur Ashe Stadium, both players struggled to hold serve.

Djokovic, cheered on by a very vocal group of Serbian fans, did well to concede just one break while Monfils failed to hold a single service game in the second set, which was far tighter than the 6-1 score suggested.

After that, Djokovic marked himself as a serious contender for Sunday's title when he wrapped up the final set in dominant fashion in 37 minutes to set up a last-four encounter with Roger Federer.
