Jonas Blixt carded his fourth round in the 60s on Sunday to earn his first PGA Tour title at the Frys.com Open.

Blixt closed with a 3-under 68 to earn a 1-stroke win over Tim Petrovic and Jason Kokrak. The Swede finished at 16-under-par 268.

"It's unbelievable. I have no words right now. This is the biggest dream I ever had," Blixt exclaimed in a televised interview. "It's really the greatest two weeks I've had on tour."

Blixt has had family members with him for two weeks now. He took third place last week in Las Vegas to gain momentum heading into this event.

"They keep me relaxed. I haven't thought about golf at all after hours," Blixt said on TV of his family. "I always practice after rounds and I haven't done that in these two weeks either. It's crazy."

Petrovic birdied the 17th to get to 15-under. He 2-putted for par at the last to post a 7-under 64. Kokrak joined him there as he eagled the drivable par-4 17th to gain a share of the lead. However, he also parred the last for a round of 68.

Jimmy Walker started on the back nine and fired a course-record tying 9-under 62 to soar into a share of fourth place at 14-under-par 270. He was joined there by Vijay Singh (68), Alexandre Rocha (68) and third-round leader John Mallinger (72).

Last year's winner Bryce Molder posted a 2-under 69 to tie for 11th at minus-11 at CordeValle Golf Club.

With as many as five different players grabbing at least a share of the lead in the final round, it came down to four players at the end.

Walker got to 14-under with three birdies in a 4-hole span from the fourth. He stumbled to a bogey on the par-4 eighth, but reached the green in two at the par-5 ninth. He 2-putted for birdie from 33 feet out to end at 14-under.

Petrovic got into the clubhouse next. He had four birdies and a bogey in the first seven holes. He made eagle on the ninth to turn at 13-under.

Birdies at 14 and 15 gave Petrovic a 1-stroke lead. He stumbled to a bogey at 16, but 2-putted for birdie on No. 17 to get back into the lead at 15-under. Petrovic parred the last, then had to wait for the final six groups to finish.

"I kind of attacked it like I was playing a one-and-done, Monday qualifier. It kept me focused all day and it seemed to work," Petrovic said.

In the penultimate group, Kokrak was two off the pace after a bogey at the 14th. He poured in a 15-foot eagle putt on 17 to join Petrovic and Blixt in the lead.

Kokrak left himself 48 feet for birdie at the last, and his putt stopped less than a foot from the hole. He tapped in for par, and waited alongside Petrovic.

It was all up to Blixt. He birdied the first two holes to join Mallinger in the lead early on. However, Blixt faltered to bogeys at three and four to fall back to 13-under.

The Swede got one stroke back as he birdied the sixth from eight feet out. He remained one shot off the lead as he ran off eight consecutive pars from the seventh.

Blixt converted a 9-foot birdie putt on the 15th to gain a piece of the lead. At the 17th, he chipped to seven feet and sank that birdie chance to move one clear of the field.

Needing a par to win, Blixt dropped his approach 38 feet from the hole at the last. He lagged that putt inside four feet. After his playing partners finished, Blixt rolled in that putt to earn his first PGA Tour win.

"On the back nine, I was just trying to hit as many greens as possible and not get too cute, and it paid off," Blixt said in an interview with Golf Channel. "I just went through my normal routine (on 18). I had two shots at it. Even if I missed it, you've still got a playoff. That's what I told myself before the putt, then over the putt I just tried to do my normal routine. And it worked."

NOTES: Blixt earned $900,000 for the victory ... He converted all 47 chances inside five feet this week ... Kokrak was also going for his first tour win, while Petrovic was trying to collect his second title ... Mallinger fell to 0-2 when owning at least a piece of the 54-hole lead on the PGA Tour ... The tour heads east next week for The McGladrey Classic, where Ben Crane fired a 63 in the final round, then parred the second playoff hole to beat Webb Simpson for his fourth PGA Tour win last year.
