Britain's Dan Evans won the first ATP 500 title of his career by beating Tallon Griekspoor in the Citi Open final in Washington DC.
Evans, now the world number 21, triumphed 7-5 6-3 against the Dutchman after a 90-minute rain stoppage.
"To do the work I've done and to stick with it and come through is [amazing]," said Evans.
American 19-year-old Coco Gauff beat Greece's Maria Sakkari 6-2 6-3 to take the women's title.
"It was really tough a couple weeks ago," said world number seven Gauff, who was knocked out in the first round at Wimbledon last month but did not drop a set in the Citi Open.
