PLAYA DEL CARMEN, Mexico - John Huh parred the eighth hole of a playoff to beat Robert Allenby and win the Mayakoba Golf Classic on Sunday.
Making his fifth PGA Tour start, Huh parred all eight holes in the playoff that matched the second-longest in PGA Tour history.
The 21-year-old Huh closed with an 8-under 65 to match Allenby at 13-under 271 on the seaside El Camaleon course. Allenby had a two-stroke lead with a hole to play in regulation, but the 40-year-old Australian closed with a double bogey.
The playoff fell three holes short of the PGA Tour record of 11 set in the 1949 Motor City Open when Cary Middlecoff and Lloyd Mangrum were declared co-winners. The playoff was the fifth to go eight holes and first since the 1983 Phoenix Open.
The playoff alternated between the par-4 18th and par-3 10th.
Matt Every and Colt Knost shot 66 to tie for third, two strokes back.
Chris Stroud was a stroke behind entering the final hole, but also made a double bogey for a 71 to drop into a tie for fifth at 10 under with third-round leader Daniel Summerhays, Dicky Pride and Alejandro Canizares. Summerhays closed with a 73, and Pride and Canizares shot 66.
Calgary's Stephen Ames finished in a tie for 16th after a final round 69 - his best result of the season. David Hearn of Brantford, Ont., was eight under through 16 holes until a bogey-double bogey finish left him with a 66 and in a tie for 49th.
Huh eagled the par-5 fifth and had six birdies in his bogey-free final round. He finished in the top 12 in two of his first four PGA Tour starts, tying for sixth at Torrey Pines and tying for 12th the following week in the Phoenix Open.
Allenby was trying to win for the first time on the PGA Tour since the 2001 Pennsylvania Classic, his fourth victory in a two-year span. He also won the Nedbank Challenge and Australian PGA in consecutive weeks late in 2009.
