In the men's draw, the title-holder Nikoloz Basilashvili of Georgia was on course to pull off a surprise against Stefanos Tsitsipas of Greece. But the 21-year-old Tsitsipas, ranked seventh, came back to win 4-6, 6-3, 6-2 and will play big-serving John Isner of the United States in the quarter-finals. Isner sent down 21 aces in defeating Britain's Dan Evans in two sets.
