India's Aditi Ashok claimed her second victory of the season in the Open de Espana as Thailand's Trichat Cheenglab won the Race to Costa del Sol title.
Ashok carded a closing 66 at Real Club de Golf Las Brisas to finish 17 under par, two shots clear of Holland's Anne van Dam.
"It was a great battle," Ashok said.
"Anne, when she's playing good, she can blow the field away and win by five to 10 shots. I knew I had to not stop making birdies and to keep trying. She is a great player and kept me honest out there."
Cheenglab could only finish in a tie for 55th after a closing 74, but that proved enough to finish top of the money list by less than 100 points ahead of Evian Championship winner Celine Boutier.
The 28-year-old is the sixth player to win both the Race to Costa del Sol and Rookie of the Year titles in the same season on the Ladies European Tour.
