Fourth seed Angelique Kerber beat Karolina Pliskova in three sets to win the Aegon Classic in Birmingham.
German left-hander Kerber, 27, had to recover from losing an opening-set tie-break to win 6-7 (5-7) 6-3 7-6 (7-4) and claim a third title of the year.
Czech 23-year-old Pliskova, who hit 52 winners to Kerber's 34, was up an early break in the third set of the two-hour, 16-minute match.
"This gives me a lot of confidence," world number 10 Kerber told BBC WM.
