Adam Hadwin finishes 6th at CareerBuilder Challenge

Adam Hadwin of Abbotsford, B.C., finished tied for sixth at the CareerBuilder Challenge on Sunday in La Quinta, Calif.

The 28-year-old shot an even-par 72 in the final round, but came in at 20-under for the tournament, along with two others, and finished just five shots back of the leaders, who entered a playoff tied at 25 strokes below par.

Hadwin began the day in third place. 

Graham DeLaet of Weyburn, Sask., shot 71 to finish tied for 42nd at 12-under-par. 

Jason Dufner won the event with a par on the second hole of the playoff, taking advantage of David Lingmerth's shot off the rocks that bounced into the water.

Dufner finished with a 2-under 70 on PGA West's TPC Stadium Course to match Lingmerth at 25-under 263. Lingmerth shot a 65, matching the best score of the day on the difficult course that was used in the tournament for the first time since being dropped after its 1987 debut.

Dufner made two great par escapes to stay alive.

In regulation on the island-green 17th called Alcatraz, he pulled his 8-iron tee shot left and the ball bounced into a narrow sandy area between rocks that circle the putting surface. Maneuvering his club around the rocks, he hooded the clubface and hooked a chip that struck the flagstick and stopped inches away.

On the first extra hole on the par-4 18th with rocks and water running the length of the left side, Dufner hit his 3-wood drive near the lip in the front of a right-side bunker. Unable to reach the green, he blasted out 100 yards to set up a 110-yard third shot that he hit to 11 feet.

Lingmerth hit his approach from the right rough to 23 feet, but missed the birdie try. Dufner then holed his putt to send the playoff back to the 18th tee.

Dufner switched to a driver and followed Lingmerth into a grass bunker on the right side. Lingmerth's approach from 184 yards crashed into the rocks along the edge of the fairway and shot left into the water.

Dufner hit the front of the green with his second shot and two-putted for par, holing a 5-footer after Lingmerth missed his par try from 22 feet.

The 38-year-old Dufner earned $1,044,000 for his fourth victory on the PGA Tour and first since the 2013 PGA Championship. He shot a 64 on Thursday on the Nicklaus Tournament Course for a share of the lead, had a 65 on Friday on the Stadium Course to take a one-shot advantage, and added a 64 on Saturday at La Quinta Country Club to pull two shots ahead.

Lingmerth also lost a playoff in the 2013 tournament on PGA West's Palmer Private Course. That year, the Swede dropped out on first extra hole after hitting his approach into the water and making a bogey. Brian Gay went on to beat Charles Howell III with a birdie on the second hole.

Phil Mickelson shot a 68 to tie for third at 21 under in his first start since the Presidents Cup in October and first since splitting with swing coach Butch Harmon to work with Andrew Getson.

Kevin Na and Andrew Loupe also shot 68 to finish alongside Mickelson.
