Feb 12 (Reuters) - Jordan Spieth shrugged off an unexpected birdie drought in the final round to clinch his ninth PGA Tour victory, by four shots at the AT&T Pebble Beach Pro-Am in California on Sunday.
A commanding six strokes ahead overnight, the world number six carded a two-under 70 on a picture-perfect afternoon of unbroken sunshine on the Monterey Peninsula to post a 19-under total of 268.
Spieth had produced a putting masterclass the previous day that yielded eight birdies on the Pebble Beach Golf Links but his putter cooled down on Sunday as he recorded just two birdies at the same venue despite playing rock-solid golf from tee to green.
