Croatia's Donna Vekic has become the first tennis player under the age of 18 to win a WTA title for eight years.
Vekic stunned top seed Dominika Cibulkova 5-7 7-5 7-6 in the Malaysian Open final, the 17-year-old seventh seed shrugging off another rain-hit day to beat the world number 10 Slovakian and win her first title.
