Seamus Power shot to the top of the Fed-Ex Cup standings and into a top-30 world ranking after a closing round 68 was enough to secure a tie for fourth at the World Wide Technology Championship at Mayakoba.

Wire-to-wire leader Russell Henley survived an early scare to win the tournament on 23-under par, four shots clear of Brian Harman.

Power, along with Scottie Scheffler, Joel Dahmen, Troy Merritt and Will Gordon were a further shot back.

Just a week after winning the Bermuda Championship, the Waterford native collected a cheque for $375,560 to move into the world's top 30 and the automatic Ryder Cup qualifying places from the World Points List.

After a couple of eagles yesterday, including a hole-in-one, on his way to a 63, Sunday's round never quite hit the same heights, though two early birdies got him to within four shots of Henley at one stage, who dropped his first shot of the week on the fifth.

However the 33-year-old American promptly birdied the next three holes and cruised to a fourth PGA Tour title, his first since the 2017 Houston Open.

Power was really chasing second position, but could only pick up one shot on the back nine, the par-five 13th which has been good to him all week.

The 35-year-old began the tournament in fifth position in the Fed-Ex Cup standings, one place above Rory McIlroy, but the eye-catching display moved him to number one for the first time in his career, ahead of Keegan Bradley and Tom Kim.

A closing 70 saw Henley equal the tournament record with a total of 23-under par.

The American, who had failed to convert any of his last five 54-hole leads into a victory, told Golf Channel: "I just tried to learn from my past and my screw-ups.

"All of those events I didn't close, they hurt and you don't know if you'll ever get to win another one, it's so hard out here.

"To come down 18 with a four-shot lead it was really cool."

Meanwhile Padraig Harrington finished in a tie for fourth in the penultimate seniors tournament of the season, the TimberTech Championship, to keep alive outside hopes of winning the Charles Schwab Cup.

Bernhard Langer shot a final-round 66 to win the TimberTech Championship by six strokes on 17-under par, with Harrington seven shots adrift after a closing round 67.

Crucially, the three-time major winner finished ahead of New Zealand's Steven Alker, who leads the overall standings going into next week's season finale, the Charles Schwab Cup Championship in Phoenix.

Alker had an outside chance of wrapping it up this weekend, but Harrington keeps alive his feint hopes of silverware with his 12th top-10 finish in 18 Champions Tour events this season to reduce gap.

Harrington closed the gap by just over 130,000 points, but a gap of 600,00 remains between the pair.

"I gained on him, that's all I could ask for," Harrington said. "Obviously I have to win next week, there's no choice there and he's got a few more scenarios that work out well for him. At least I kept it going."
