Irishman Seamus Power has waited a long time for his maiden career PGA Tour victory and he had to endure six playoff holes to claim the Barbasol Championship over J.T. Poston on Sunday.

Power and Poston finished the final 18 on Sunday tied at 21 under, before it required six playoff holes to split the pair at Keene Trace Golf Club in Kentucky.

Playing the 18th hole for the fourth time in the playoff, Poston made a costly error when he teed off into the penalty area with the ball bouncing into the water.

Power capitalised by making par for the sixth time in the six playoff holes, despite missing his initial putt.

The triumph marks 34-year-old Power's first on the PGA Tour, coming in his 106th start.

Power said: "It's been a bit of a struggle of a season early. I've found a bit of form recently. This changes everything for me. Forever I'll be able to say I'm a winner on the PGA Tour."

The Irishman had earlier carded a five-under-67 on the final round as Poston, who led by four shots at one stage, let it slip.

Poston was not helped by a double bogey on the 15th hole after his drive landed marginally out of bounds, before Power birdied on the final hole to force extra holes.

India's Anirban Lahiri carded an exceptional final round seven-under-65 to finish one shot behind the lead pair, along with American Sam Ryder who had seven birdies on the final day.

Lahiri and Ryder carded 20 under across 72 holes, with Patrick Rodgers, Henrik Norlander, Ryan Armour, Mito Pereira, James Hahn and Luke List all finishing at 19 under.
