British No.1 Jack Draper produced a stunning fightback to beat world No.11 Stefanos Tsitsipas and reach the third round at the Cincinnati Open in Ohio
Draper had required a medical time out during his first-round win over Jaume Munar, but appeared to be moving freely during the early exchanges.
Tsitsipas made a decisive break on Thursday to lead 3-1 and despite picking up shot-clock violations, the Greek world No.11 fended off a couple of break points for Draper before closing out the opening set.
Draper, 22, regrouped for the second set, his serve this time holding up well, before forcing home a break-point opportunity in the 10th game following a double-fault by Tsitsipas to level the match.
The Brit, though, was soon under pressure again as Tsitsipas had three break points in the opening game of the deciding set, but Draper recovered for a crucial hold.
Tsitsipas looked to have taken a decisive break in the ninth game, only to then find himself 0-40 down following another call for time violation and a double fault, which saw Draper back on level terms at 5-5.
Draper, currently ranked 28 in the ATP standings, held to put the pressure back on Tsitsipas before converting a superb return to seal another hard-earned victory, 3-6 6-4 7-5.
