Mahan rallies to win The Barclays
Mahan carded a 6-under 65 in the final round at Ridgewood Country Club to end at 14-under-par 270. He collected his sixth career victory on the PGA Tour and first since the 2012 Houston Open.
"I haven't played my best this year, so to get a win in an event like this and the timing that is what feels unbelievable. I'm extremely proud of myself right now," said Mahan. "I knew this was around the corner, but to do it and to do it today with a 65 was great."
Jason Day, who held a share of the third-round lead with Jim Furyk, shot a 3- under 68 to end in a tie for second place with Stuart Appleby (65) and Cameron Tringale (66) at 12-under 272.
Ernie Els (66), William McGirt (66) and Matt Kuchar shared fifth at 11-under, while Furyk managed a 1-under 70 to end alone in eighth at 10-under 274.
Rickie Fowler (67), Patrick Reed (65), Kevin Na (69) and Morgan Hoffmann (69) tied for ninth at minus-9.
Playing in the penultimate group ahead of the overnight leaders, Mahan opened his day with a 7-foot birdie putt at the first to join Day and Furyk at 9- under.
Day answered with a 16-foot birdie at the first to move into sole possession of the lead before Furyk converted his 15-foot birdie effort at the second to again meet Day atop the leaderboard.
Reed made a late run with three straight birdies from the 15th to meet Mahan at 9-under before Tringale poured in birdies at the third and fifth to make it a three-way tie for third place.
After Day and Furyk each traded birdies at the third with bogeys at the fourth to remain at 10-under, Day poured in a 7-foot birdie putt at the fifth to claim the outright lead.
Mahan would then kick in a short birdie at the fifth and Tringale converted a birdie at the ninth to join Furyk at 10-under before a 2-shot swing at the sixth moved Furyk into the lead.
That swing included a 17-foot birdie putt to move Furyk to minus-11, while Day 2-putted for bogey from six feet to fall to 10-under.
Day, however, bounced right back with a birdie at the seventh to reclaim a share of the lead, and was handed sole possession of first when Furyk 3-putted for bogey at the ninth.
Appleby, meanwhile, had a pair of birdies and a bogey during his front nine before reeling off three straight birdies from the 10th to join Tringale, Mahan and Furyk at minus-10.
Mahan birdied the 11th to join Day atop the leaderboard before Appleby continued his surge with a 5-foot birdie at the 14th and a 10-foot birdie effort at the par-3 15th to claim the outright lead at minus-12.
Appleby parred his final three holes to end there.
"I felt the nerves, but I dealt with them nice," Appleby said. "It was nice to roll the ball and get some putts to drop."
Day lost his share of second place when he sailed his tee shot at the 11th well right and next to the green of an adjacent hole, resulting in a bogey.
Tringale replaced him at 11-under with a birdie at the 15th, and Els closed his bogey-free round with consecutive birdies at the 17th and 18th to finish at 11-under.
The jostling atop the leaderboard continued when Mahan birdied the 13th and Tringale birdied the 16th to make it a three-way tie at 12-under.
Mahan broke from the pack with an 11-foot birdie effort at the 15th and after Tringale rolled in his third straight gain at the 17th to also reach minus-13, Mahan kicked in a short birdie at the 16th to claim the lead for good.
Mahan stretched his advantage to two shots when he poured in a 22-foot birdie putt at the 17th. That lead was pushed to three following Tringale's bogey at the last.
"I really didn't feel nervous out there. I just felt comfortable. I felt like I was in control of what was going on," said Tringale.
Mahan found trouble at the last when he pushed his tee shot to the right and needed to punch out with his second, but he was able to convert an 8-foot bogey putt to end at 14-under and clinch the victory.
Day had bounced back from his bogey at the 11th with birdies at the 13th and 14th to get to 12-under, but he could not pick up any more shots and Mahan's bogey save at the last put the tournament out of reach.
NOTES: Mahan collected $1.4 million with the win and also moved to the top of the FedExCup points list ... Furyk earned his 13th top-10 finish in the FedExCup Playoffs, tying Steve Stricker for the most all time ... The tour moves to Massachusetts next week for the Deutsche Bank Championship, where Henrik Stenson won last season.
