The 26 year old from Pampiona in Spain, took advantage of a faltering Lee although the winner herself had to rebound from a horror finishing stretch having dropped four shots in her last five holes after playing her first ten holes in five under.
Lee needed only a par at the par five last to win in regulation but she found the water with her second and took bogey. It was becoming a comedy of errors but Ciganda was able to get up and down for birdie at the first extra hole to win.
Ciganda had been three times runner-up on the LPGA Tour prior to this week and as one of the best amateurs in European golf prior to turning professional this win has been long anticipated.
The pair finished one shot ahead of China’s Shanshan Feng and Korean Min-Sun Kim.
Su Oh led the Australians, finishing in 29th position while Minjee Lee was 37th.
The LPGA Tour now moves to Hainan Island in China for the Blue Bay LPGA.
