Tobias Kamke wins Legg Mason opener

WASHINGTON -- Tobias Kamke of Germany beat 18-year-old wild-card entry Denis Kudla of the United States 6-4, 6-2 in Sunday's only main-draw match at the Legg Mason Tennis Classic.

Playing much steadier, Kamke made only 12 unforced errors, 19 fewer than Kudla, who lives in Arlington, Va. Kamke broke serve to open the second set and was on his way, wrapping up the victory in 70 minutes.

Kamke will face 11th-seeded John Isner -- winner of the longest match in tennis history -- in the second round. Isner and the other 16 seeded players at the hard-court tuneup for the U.S. Open all received first-round byes.

Among the players scheduled to compete Monday, the first full day of action, are James Blake and Donald Young of the United States, and 6-foot-10 Ivo Karlovic of Croatia.

The tournament's top-seeded player is No. 7-ranked Gael Monfils of France, followed by Mardy Fish of the U.S., a finalist each of the past two weeks on the ATP tour.

Andy Roddick, the 2003 U.S. Open champion and a three-time champion in Washington, pulled out of the tournament last week, citing a side muscle injury.
