Thailand's Mink Nutcharut beat England's Reanne Evans at the English Open in the first match between two female players on the professional World Snooker Tour.
Nutcharut won three successive frames to claim a 4-2 victory in the ranking tournament in Brentwood, Essex.
The 24-year-old's reward for victory over fellow former women's world champion Evans, 38, is a match against Ricky Walden in the second round.
Ronnie O'Sullivan, Judd Trump and world champion Kyren Wilson join the tournament from round three in pursuit of a £100,000 top prize.
