WASHINGTON (AP) - Playing his first match since a semifinal loss at Wimbledon, top-seeded Juan Martin del Potro beat American Ryan Harrison 6-1, 7-5 on Thursday at the Citi Open.

Del Potro, who received a first-round bye, was scheduled to face 14th-seeded Bernard Tomic of Australia later Thursday.
The match between 2009 U.S. Open champion del Potro and Harrison originally was supposed to be played Wednesday, but rain washed out part of the schedule.
