Seamus Power chipped in from close to 25 yards for a closing eagle as Patton Kizzire beat James Hahn at the sixth extra hole to win the Sony Open to become the first multiple winner on the PGA Tour this season.

The West Waterford man's three at the ninth, his 18th, saw him close with a three-under 67 to finish tied for 54th on six-under, earning €14,198 and just six points in his first start of 2018 to lie 134th in the 2017-18 FedExCup standings.

Power (30) also made two bogeys and three birdies in the final round at Waialae Country Club in Honolulu, but it was his short game that made up for an average week from tee to green as he ranked third for strokes gained around the green.

The Tooraneena man got up and down from nine bunkers out of nine over the four rounds and holed twice from off the green on the final day, using his putter on the green just 23 times.

Tom Hoge was leading with three holes to go but double-bogeyed the 16th and then missed a 10 footer for birdie at the 18th to shoot 70 and finish third on 16-under-par.

Kizzire (31), who won the OHL Classic in Mexico last November, closed with a two-under 68 but ended up in a playoff on 17-under 263 as James Hahn shot 62 in the final round.

After two pars and two birdies at the par-five 18th, they also made pars at the par-3 17th before Hahn blinked first when they played on the same hole for a second time, lipping out for par after putting up to eight feet from right of the green.

"It wasn't pretty," Kizzire said. "I'll take it any way I can get it."

According to reports, two-time PGA Tour winner Hahn had birdie putts from 10 feet and six feet on the par-5 18th hole at Waialae Country Club that would have won it. 

Kizzire had to get up-and-down from a bunker for par on the first extra hole, making a seven-footer to stay alive in what was the longest playoff on the PGA Tour since Bryce Molder won the Frys.com Open in 2012 after eight extra holes.

The week was marked by an incoming missile warning on Saturday that turned out to be a false alarm and a final day strike that saw union workers for video and audio production at Golf Channel events.

Golf Channel could only provide limited coverage but according to reports, they had enough cameras to cover the final three holes and the entire playoff, with commentary coming from headquarters in Florida.
