Dan Evans progressed to the final of the Citi Open with a straight-sets victory over Grigor Dimitrov in Washington.
The British number two eclipsed his Bulgarian opponent 6-3 7-6 (4) in just under two hours to set up a meeting with Tallon Griekspoor of the Netherlands.
Despite being overmatched in the power department, Evans put together a clean and composed performance as a sloppy Dimitrov was left to rue his own mistakes.
The world number 20 fired 24 winners to just nine from Evans, but came unstuck with 30 unforced errors.
Evans is the first British player to reach the final in Washington since Andy Murray in 2006.
Meanwhile, Griekspoor rallied from a set down in his semi-final clash with American Taylor Fritz as the world number 37 seeks his third title of the season.
