Seamus Power continued his excellent recent form with a top-10 finish at the World Wide Technology Championship in Mexico.

The Waterford man carded a final-round 66 to climb into a tie for eighth on 18 under par, five shots behind winner Blades Brown, who defeated Ben James in a play-off.

Power came out on the wrong end of a play-off himself at last week's Butterfield Bermuda Championship, but he continued his climb up the FedEx Cup rankings with a third top-10 finish in his last four starts.

The 39-year-old is now ranked 137th in the world, his highest ranking in over a year, after pocketing $169,500 in Mexico.

Brown, meanwhile, became the fourth-youngest winner in PGA Tour history and the youngest since 1931.

At 19 years, five months and 18 days old, the American prodigy is nearly six months younger than Jordan Spieth was when he won the 2013 John Deere Classic, the last time the tour had produced a teenage winner.

Brown carded a nine-under-par 63 on Sunday to finish tied with James on 23 under, with the latter forcing a sudden-death play-off thanks to an eagle at the 18th.

Both golfers birdied the first play-off hole, but Brown prevailed with another birdie at the second to secure his maiden PGA Tour victory.

"I'm just so obsessed with this game," Brown said after his win.

"It tests you in so many different ways, and I think it's a good metaphor for life. Sometimes you hit it just how you want to and you get a bad break, and sometimes you don't hit it very well and it goes to 2 feet. So you kind of just got to play it wherever it lies.

"I love golf, I love all the stuff that goes into it and can't wait for what's next."
