Seamus Power had his worst round of the week on Sunday but he did enough to fend off the challengers and claim the Butterfield Bermuda Championship with a score of 19 under par.

It is the second PGA Tour title of Power's career after the 2021 Barbasol Championship, but it was anything but smooth sailing down the stretch.

Power owned a share of the lead heading into the final round after a trio of 65s, and he was bogey-free with three birdies through 12 holes on Sunday before the nerves began to show.

He posted bogeys on 13, 15 and 16, but a birdie on 17 gave him a two-stroke lead on the final hole, and he needed that buffer as he also bogeyed the last to close with a 70.

Speaking to NBC after stepping off the 18th green, Power called the course "a tale of two sides", and reflected on how different it feels to get his second win.

"I knew it was going to be really hard coming in, and it was," he said. "I made hard work of it in the end, but delighted to get it done.

"It's a completely different feeling [from my first win], but just as special. It's just so hard, I've played a lot of tournaments and it's only my second win from – I don't even know how many events.

"It's amazing, it's special, it's going to take a while to sink in, but absolutely over the moon."

Alone in second place at 18 under was Belgium's Thomas Detry, while the joint-leader heading into Sunday, Ben Griffin, shot a one-over 72 to finish tied for third at 17 under.

Joining Griffin was Taiwan's Kevin Yu and America's Patrick Rodgers, with the latter's 65 tying for Sunday's second-best score.

Two Australians worked their way into the top-10 as Aaron Baddeley finished tied with Denny McCarthy for sixth place at 16 under, while Harrison Endycott was two strokes further back alone in 10th.
