Alexandr Dolgopolov earned his second ATP World tour-level title on Sunday. The Ukrainian beat 34-year-old Tommy Haas of Germany in three grueling sets with a 6-7(7), 6-4, 6-1 scoreline at the Citi Open in Washington, D.C.

By winning this ATP World Tour 500 tournament, Dolgopolov also moved on to the second-place and tied with Atlanta champion Andy Roddick in the US Open Series Bonus Challenge Standings.

"For sure, I’m very happy, and especially winning a match like that really tight, goes up and down, the rain breaks," said Dolgopolov. "I’m really happy with myself that I stayed concentrated and was in the match in all the three sets."

The final, which was scheduled to start at 4 p.m. local-time, interrupted due to rain and finally started around 7:45 p.m. The German earned the first set in a stiff tie-breaker and then Dolgopolov played superbly to earn the equalizer. Finally, the Ukrainian won this duel in two hours and 15 minutes.

Dolgopolov further added that "He was giving away more free points than he did in the first set and throughout the tournament when I watched him play. I think it was a part of him, a part of it being the final, a part of my game. Everything helped it to go wrong for him. He helped me a little bit in the last game of the second set. In the third set he was a bit frustrated, so it was really good I got an advantage at the start of the set."

On the other hand, Haas lamented, "Obviously I’m a little bit frustrated right now still. I thought I had some chances to win this title and I really wanted it. It’s always tough to lose, even when you had a great week, but you just have to let it sink in and overall, I’m really proud to get here to a final and play really solid tennis. I just hope I can stay injury-free and keep going and try to keep it moving."
