British number one Jack Draper fought back from a set down to beat Stefanos Tsitsipas and reach the Cincinnati Open third round on Thursday.
Tsitsipas, ranked 11th in the world, broke for 5-4 in the deciding set, but Draper won 12 of the last 17 points to wrap up a 3-6, 6-4, 7-5 victory.
“In general my grit, my determination and attitude won me the game today, so I am very proud of that,” Draper, the world number 28, said in his on-court interview.
The 22-year-old will face Norwegian seventh seed Casper Ruud or Canada’s Felix Auger-Aliassime next.
Tsitsipas, a former runner-up at the Australian Open and French Open, was playing in his first tournament since stopping his coaching partnership with his father Apostolos.
