Germany's Olivia Cowan holds a slender lead after an opening round 65 at the Andalucia Costa Del Sol Open de Espana Femenino.
Cowan fired an eagle and five birdies at Aloha Golf Club to finish seven under par, a shot ahead of Norway's Marianne Skarpnord, who tops the Order of Merit in the penultimate event on the Ladies European Tour.
America's Christina Kim lies two shots off the lead following a 67, with defending champion Anne Van Dam, Cheyenne Woods and Karolin Lampert a stroke further adrift.
Scotland's Kylie Henry is four shots off the pace after a 69 containing four birdies and a solitary bogey.
Leona Maguire, who will start as a full member of the LPGA tour when it resumes in January, shot three birdies and four bogeys in a one-over 73.
