He was right.
Dufner and Snedeker birdied the last two holes in better ball on Saturday and won the Franklin Templeton Shootout by two shots. The Dufner-Snedeker team finished at 30-under 186 at Tiburon Golf Club.
"I'm pretty consistent, I'm in the fairway, I'm on the greens. That gives him a lot of confidence," Dufner said. "He putts really well so that gives me more confidence. I was able to stroke the ball a lot freer this week."
Added Snedeker: "I play with Jason a lot and this is the best I've ever seen him roll it."
Harris English and Matt Kuchar, who have finished first, second and second the past three years, shot 28 under for second. Charley Hoffman and PGA Rookie of the Year Daniel Berger finished at 27 under.
Hoffman and Berger, who led by a shot after Friday's round, struggled early, particularly Hoffman.
Dufner-Snedeker, starting one shot back, had six birdies on the front nine. A Snedeker chip-in from 30 feet on No. 3 helped get them off to a good start.
"I thought today we did exactly what I thought we had to do," Snedeker said.
They followed with birdies on Nos. 10, 12, 13, 17 and 18 as they kept attacking.
"The key for us was 17," Snedeker said. "(Jason) made a clutch, tough 4-footer down the hill that gave us the lead going into the last home.
English-Kuchar missed some of the putts they made on their way to the 2013 title. One of the putts that left Kuchar particularly frustrated was a 4-footer he sent long on No. 15.
"On 15, it was left to right, which is not easy and the wind was going with the break," Kuchar said. "Usually, that's one I make most of the time. It's a bummer to miss it.
"We had good putts and it was a good week but to win, you certainly have to make ones inside 10 feet and then make a couple of others."
