Jack Draper overcame a second-set wobble against Karen Khachanov to win the final of the Erste Bank Open 6-4, 7-5 on Sunday for his second ATP title. The 22-year-old Briton won the opening set in Vienna and led 4-0 in the second before Khachanov took five games in a row. “I was playing so good, and then the momentum shifted,” the seventh-seeded Draper said.
