Sepp Straka birdied three of the final five holes to clinch his maiden PGA Tour triumph after overnight leader Daniel Berger crumbled at the Honda Classic on Sunday.

Straka became the first-ever Austrian to win a PGA Tour title while he was the sixth first-time winner on the tour this season.

The 28-year-old Austrian started the final day tied for second in a group of four alongside Shane Lowry, Kurt Kitayama and Chris Kirk who were five strokes behind Berger.

But Straka carded a final-round four-under-66 highlighted by his late flurry in wet conditions at Palm Beach Gardens to win outright at 10-under overall.

"They were pretty tough [conditions]," Straka said after the win. "For a little while the wind let down before the rain started which was nice but on the last hole, that second shot into the green it started pouring rain. I was glad I could hit that one on the green two-putt."

Straka and Lowry went into the 18th hole tied at nine-under, but the Irishman could only make par, while the Austrian's two putt earned him the decisive birdie.

Lowry had led by as much as two strokes down the back nine but Straka surged with a fine approach on the 14th setting up birdie, while he sunk a birdie putt from off the green on the 16th to draw level.

Kitayama finished third at eight-under, with Berger's final-round four-over-74 seeing him slide from a five-stroke lead to three shots off the pace.

The American, who resides nearby to Palm Beach Gardens in Florida, saw him lead evaporate quickly, with a double bogey on the third hole, along with bogeys on the fifth and sixth.

Berger, ranked 20th on the PGA Tour, holed a clutch bunker shot on the seventh hole along with a chip for birdie on the 14th but could not do enough to retrieve his lead.

Needed eagle at 18.
