PEBBLE BEACH -- James Hahn, the 31-year-old tour rookie from Alameda and Cal and the third-round co-leader of the AT&T Pebble Beach National Pro-Am, knew it was Brandt Snedeker's day on Feb. 10 after his playing partner made birdies on the sixth and seventh holes to open up a three-shot lead.

"I felt like that was the turning point," said Hahn, who closed with a 70. "I'm sure if you ask him, it was never a doubt that he was going to win the golf tournament."

Snedeker shot a 7-under 65 to finish with a winning score of 19-under 267. Chris Kirk shot 66 on Dec. 10 to end up with a score of 269 and Hahn had a four-round score of 272 which tied for third place.

Hahn matched Snedeker off the tee and in the fairways but faltered on the greens in the final round. He missed a makable eagle putt on No. 2, a short birdie putt on No. 3 and, after finally finding the bottom of the cup for birdie on No. 4, gave it back with a bogey on the par-3 fifth.

So what did Hahn learn from playing in the final group for the first time?

"I need to work on my putting," he said. "(Snedeker) rolled them in early. I didn't, and he rolled them in late and I didn't. That's kind of the difference."

Hahn claimed his biggest check yet in golf -- $338,000. But he still wasn't quite sure how he felt.

"Being so close to winning a golf tournament, playing in the final group, it's a little bittersweet," he said.

In the third round on Feb. 9, Hahn scalded Spyglass Hill with a bogey-free 6-under 66, and he and Snedeker were a shot ahead of Kirk, who posted a 6-under 64 at Monterey Peninsula. Hahn backed up an opening-round 71 at Pebble Beach on Feb. 7 with a 5-under 65 at Monterey Peninsula in the second round on Feb. 8.
