Juan Martin Del Potro Has Won 12 Straight Matches In Washington, Plays Haas Tonight

Juan Martin Del Potro won his 13th straight match at the Citi Open Washington last night, beating the hard-serving Kevin Anderson 76, 63 to reach the semifinals. Del Potro won the tournament in 2008 (Andy Roddick) and the following year in 2009 (Viktor Troicki) but due to injuries and other issues he hasn’t returned until this week, and he’s continued to dominate the event.

On his way to the 2008 triumph, Del Potro beat both John Isner and Tommy Haas in the event. He’ll play the 35-year-old Haas again tonight then possibly Isner, who meets Dimitry Tursunov, in the Sunday final.

“He has given me a lot of troubles,” said Haas who is 0-4 against the Argentine, never having won a set. “He is such a sound player from the baseline. He moves pretty well for being very tall, and he just has great ground strokes. I’ve always tried to have different game plans [when] playing against him, and when I played him in Indian Wells, it totally went out the door.

“It’s going to be a big challenge. I hope I mix it up, play well, be aggressive, and not give him too many easy points.”

Can Del Potro get to lucky No. 13?

Also important for Del Potro is no issues with his knee after two scary falls at Wimbledon.
