Canada's Nick Taylor has made an 11-foot birdie putt to beat Charley Hoffman on the second hole of a play-off, after carding birdies on three of the last four in regulation play to cap a wild week at the Phoenix Open.
Taylor closed with a six-under-par 65 to reach 21-under 263, the seemingly nerveless Canadian forcing the play-off with a nine-foot birdie putt on the par-4 18th.
Both players birdied the extra hole and hit the green on No.18 a second time.
Hoffman left his birdie putt short and Taylor birdied the hole for the third time in less than an hour as the sun dipped below the horizon.
Success brought a fifth PGA Tour title to end a chaotic week of weather delays and the rare decision to close the gates - and cut off alcohol sales - when the traditional party atmosphere started to get out of hand on Saturday.
Taking advantage of the first pleasant day of the week in the desert, Hoffman moved into contention with a 64 on TPC Scottsdale's Stadium in the morning to complete his weather-delayed third round.
Hoffman was four under in a three-hole stretch on the back nine and had a three-shot lead when he finished.
But Taylor refused to let the trophy go.
The Canadian shot a course-record 60 in the opening round for a five-shot lead that matched the largest after 18 holes on the PGA Tour since 1983.
He finished off a third-round 68 on Sunday morning, but stagnated after a birdie at No.9 in the afternoon.
He came to life with consecutive birdies starting on No.15 and finished with a flourish after just missing a birdie putt on the 17th.
Australia's Adam Scott finished tied for eighth, following his third round 65 - the joint-second best of the day behind Hoffman - with a 66 on Sunday afternoon.
Five birdies, and an eagle on the par-5 15th, allowed the former world No.1 to surge up the leaderboard on the final day.
Three birdies on his back nine left fellow Aussie Aaron Baddeley (68) tied for 28th at eight under, while Min Woo Lee (73) ended a forgettable week in joint 71st.
Two-time defending champion Scottie Scheffler (66) surged into contention with five straight birdies to complete his third round.
The world No.1 briefly held the lead early in the final round before his putter went cold, ending his bid for the PGA Tour's first three-peat in 13 years.
He shot 66 to tie with Sam Burns for third at 18 under.
