Rookie Russell Henley has made an immediate impact on the PGA Tour by claiming the Sony Open title in Hawaii.
Playing in his first PGA Tour event, the 23-year-old was in record-breaking form as he held off the challenge of Tim Clark to win by three shots.
Henley's final total of 24-under-par was a tournament scoring record and the best-ever 72-hole score in PGA Tour history.
Henley made the ideal start after he birdied the first, but he picked up his first bogey of the tournament on the par four eighth.
Undeterred, Henley picked up shots on nine and 10 before he birdied the final five to finish clear of the chasing pack.
South African Clark had put up a brave fight as he carded a final-round 63 but it just wasn't enough.
Charles Howell III finished third thanks in part to an eagle on the par three ninth, which was the backbone of a solid round of 66.
Howell didn't drop a shot in the final round, as birdies at five and 15 saw him to an overall score of 17 under par.
Scott Langley faded out of contention with a poor back nine. The 23-year-old was just two shots off the lead after the 11th hole, but bogeys on the par four, 13, 15 and 16 cost the rookie any hope he had of picking up a tour win on his first appearance.
