SCOTTSDALE, Ariz. —
Mickelson parred the par-4 18th after another drive to the left, one that easily cleared the water he hit into Friday en route to a double bogey, and Snedeker closed with a bogey.
Mickelson had his third wire-to-wire victory and first since the 2006 BellSouth Classic — a 13-stroke blowout the week before the second of his three Masters victories. He pushed his victory total to 41, winning for the first time since 51 weeks ago at Pebble Beach — where he will go for a record-tying fifth victory next weekend.
Making his 24th appearance in the event that he also won in 1996 and 2005, Mickelson tied the tournament scoring record set by Mark Calcavecchia in 2001, and joined Calcavecchia, Arnold Palmer and Gene Littler as the only three-time winners. With six victories in Arizona, Mickelson also matched Johnny Miller's tour record.
After three nearly cloudless days in the Valley of the Sun, the final round was played in overcast conditions. Light rain even fell for a few minutes as Mickelson finished warming up on the practice green and played the first hole.
As the rain stopped, Mickelson bogeyed the par-4 second. He rebounded with birdies on the two front-nine par 3s, pulling off the sensational putt on No. 7.
Snedeker pulled within three strokes with a birdie on the par-4 ninth, but Mickelson pushed the advantage back to four with a two-putt birdie on the par-5 13th, his fourth straight birdie on the hole. Snedeker saved par after his drive stopped under jumping cholla, forcing him to take a drop for an unplayable lie.
Mickelson matched Snedeker on the next two holes, saving par on the par-4 14th with a 10-foot putt and two-putting for birdie on the par-5 15th. Snedeker pulled within three again on the par-3 16th, hitting to 5 feet on the stadium hole, and matched Mickelson's birdie on 17.
