Japan's Kanna Takanashi had a TV crew watching her every move during the Evian Tour's Costa Azul Open, near Lisbon but showed her resolve to carry off her first professional title.
The subject of a fly on the wall documentary by a Canadian TV company the 32-year-old from Tokyo created an ending they could hardly have scripted by with a birdie at the final hole to take the title by one shot from Scot Julie Forbes.
Her five under par total - thanks to a closing 70 at Aroeira which included seven birdies two double bogeys and a bogey - held off Forbes, who finished with a best of the week 68.
Tied third were were England's Nicola Moult and New Zealander Lynnette Brooky who both carded 70s.
Swede Nine Karlsson was tied for the lead when her approach found water at the last. She eventually finished fifth.
Takanashi, who earned a conditional Qualifying Tour card at the second attempt on this course in October thanked her local caddie in helping to read the subtle greens.
"I am shaking now with goose bumps. I was very nervous out there," she said.
This week the Tour moves to Salamanca for the Caja Duero Spanish Open.
*Alison Nicholas, the former US Women's Open champion from Birmingham, showed an encouraging return to form with a seventh place finish in the LPGA's Corning Classic in New York.
Her eight-under par total was six behind the winner Laura Diaz and earned her $20,400. Becky Morgan was tied 13th and Mhairi McKay and Catriona Matthew 27th.
