WASHINGTON, D.C. (AP) - Second-seeded Alexandr Dolgopolov won the Citi Open on Sunday night for his first ATP World Tour 500 event title, beating fourth-seeded Tommy Haas 6-7 (7), 6-4, 6-1.
The 25th-ranked Dolgopolov's previous three finals appearances, including one victory, came in 250-level events.
There were two rain delays in the first set, one for about 15 minutes and the other for about 1 hour, 35 minutes.
Haas won the first-set tiebreaker to hand Dolgopolov his first set loss of the tournament.
Both players held serve in the second set until Dolgopolov, from the Ukraine, broke Haas in the final game for the German's first set loss in the tournament. Dolgopolov broke Haas' serve twice in the final set.
