Patton Kizzire survived a late charge from tournament favourite Rickie Fowler to win his maiden PGA Tour title at the OHL Classic at Mayakoba in Mexico.
Players had to complete 36-holes on Sunday after a rain-affected tournament and the final group had a great battle.
After three nerveless par saves at 12, 13 and 14, Kizzire was three ahead with three to play but back-to-back birdies from Rickie Fowler meant it would be a nervy finish.
Par at the last was enough for Kizzire to lift his first PGA Tour title in his 62nd start.
The 31-year-old shot rounds of 66 and 67 on Sunday, whilst Fowler posted a pair of 67s.
