PEBBLE BEACH, Calif. — Jordan Spieth kept it simple Sunday and won the AT&T Pebble Beach Pro-Am for his ninth PGA Tour title.

Spieth started with a six-shot lead and no one got closer than three all day. He putted for birdie on all but one hole and closed with a 2-under 70 for a four-shot win over former U.S. Amateur champ Kelly Kraft, who shot 67.

U.S. Open champion Dustin Johnson shot 68 to finish third.

The scenery was as spectacular as it gets on the Monterey Peninsula. The final round was on the dull side, and that was just fine with Spieth.

It was his first 54-hole lead on the PGA Tour since the Masters, where he lost a five-shot lead on the back nine at Augusta National. The 23-year-old Texan ran off 14 straight pars until a 30-foot birdie on the par-3 17th. That allowed for an easy walk up the 18th with a four-shot lead.

Spieth’s only other birdie was on the par-5 second when he two-putted from 12 feet. He finished at 19-under 268.

Two-time Pebble Beach winner Brandt Snedeker, playing in the final group with Spieth, managed three birdies through six holes to get within four shots. But he narrowly missed birdie chances on the fifth and seventh holes, and he fell back with a bogey on the ninth. Snedeker closed with nine straight pars for a 70 to finish fourth.

CHAMPIONS: Scott McCarron eagled the par-5 18th hole to win the Allianz Championship in Boca Raton, Florida, for his third victory in his last 17 starts on the tour.

The 51-year-old McCarron hit a 6-iron shot from 178 yards to 8 feet to set up the eagle, his second of the day. He closed with a 5-under 67 for a one-stroke victory over Kenny Perry and Carlos Franco.

EUROPEAN TOUR: Fabrizio Zanotti of Paraguay shot a final-round 63 after a birdie and eagle on his closing two holes to win his second European Tour title at the Maybank Championship in Kuala Lumpur, Malaysia.

He claimed a one-shot victory over American David Lipsky, who closed with a 67.
