Dan Evans advanced to the last 16 of the Citi Open in Washington after a straight-sets victory over former world No 8 Grigor Dimitrov.
Evans, who reached the third round in Wimbledon, overcame a late slip-up to sweep the Bulgarian, who was the 12th seed at the ATP World Tour 500 event.
The British No 4 was at the top of his game virtually throughout to set up a date with either Lukas Lacko or Jack Sock for a place in the quarter-finals after the 6-4, 6-4 win over the Bulgarian.
The Bulgarian was down 3-1 early in the first set and was unable to rally.
In the second set, Evans had three match points to close out the contest at 5-2 but Dimitrov saved all three before breaking the Briton’s serve and then holding his own.
However, Evans held his nerve when serving for the match for a second time and converted his fifth match point to secure the victory.
‘I was not playing good tennis,’ Dimitrov told the Washington Post. ‘Missing a lot of balls. Focus wasn’t good at all.’
In the women’s draw in Washington, British number three Naomi Broady won her first WTA Tour main draw game since April with a straight-sets success over Irina Falconi.
Broady, ranked at 84 in the world, despatched the home hope 6-3 6-4 to get that winning feeling for the first time since the Katowice Open three months ago.
After an early exchange of breaks the Stockport-born player crucially broke again at 4-3 and then served out the first set, with a break in the third game proving decisive in the second which allowed her to take the match in 87 minutes.
Second seed Sloane Stephens of America or Japan’s Risa Ozaki will be her opposition in the second round.
