Canada's Milos Raonic defeated countryman Vasek Pospisil 6-1, 6-4 in the Citi Open final in Washington.
"I think I'm playing at a high level. I think the number I have beside my name is not a coincidence and I don't think it would be a coincidence if it got lower," the 23-year-old Raonic said.
The win helped the Canadian move up a spot in the ATP rankings to No. 6.
The match marked the first time that two Canadians had met in the final of a tournament in the Open Era.
"It's great the way it started," said Raonic. "I couldn't have asked for more. I had a chance to break in every single game in that first set. Then I continued to play solid after that. All in all, a very good performance and an important moment for me," Raonic said.
Raonic earned 500 ranking points and took home a check for $316,400.
The Canadian also tied American John Isner, who won the title in Atlanta, for first place in the US Open Series Bonus Challenge Standings.
Raonic and Isner each have 70 points in the US Open Series, while the 24-year-old Pospisil is in second place with 60 points.
On the women's side, Russia's Svetlana Kuznetsova defeated Japan's Kurumi Nara 6-3, 4-6, 6-4.
"It happened a little bit like this earlier in the year in Oeiras - I was up 4-1 in the third set in the final but lost the match," Kuznetsova said. "Today when I was up I was getting tight, but in the third set I was just trying to hold my serve, and in the last game I knew I just needed four more points."
The 29-year-old Russian, a two-time Grand Slam winner, had not won a WTA title since Aug. 8, 2010, when she won in San Diego.
"It feels like it's been too long," Kuznetsova said. "When you've won Grand Slams, not winning tournaments is hard, but you just keep trying your best every time you play." EFE
