SANTO ANTONIO DA SERRA, Portugal (AP) - American Peter Uihlein won the Madeira Islands Open on Sunday in his 16th European Tour start for his professional title, closing with a 4-under 68 for a two-stroke victory.
Uihlein, the former Oklahoma State star who won the 2010 U.S. Amateur, birdied four of his last eight holes to finish at 15-under 273 at Santo da Serra.
``I'm just thrilled,'' Uihlein said ``To do it playing well on the back nine, coming down the stretch, is sweet. ... I just knuckled down I guess. It was all putting that did it today, I was just trying to free up and they started to roll in so it was nice.''
The 23-year-old Uihlein earned a European Tour exemption through next season. His father, Wally Uihlein, is the chief executive golf apparel and equipment manufacturer Acushnet.
``You grow up quick out here and that was the main reason I came over,'' Uihlein said. ``It's been a good process so far and hopefully I can keep going.''
He has three top-10 finishes in seven European Tour events this season.
Denmark's Morten Orum Madsen had a double bogey on the 18th for a 67 to tie for second with Chile's Mark Tullo. Tullo, the third-round leader, had a hole-in-one on No. 4, but had four bogeys in a 71.
Scotland's Craig Lee closed with a 71 to finish three strokes behind Uihlein.
