Djokovic into fourth straight U.S. Open semi

By Matt Majendie

NEW YORK (Reuters) - Serbia's Novak Djokovic defied high, swirling winds to reach the semi-finals of the U.S. Open for the fourth consecutive year with a convincing 7-6 6-1 6-2 victory over Gael Monfils on Wednesday.

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 shotmaking, 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 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."

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.
