His opening round of 60 on Thursday set the platform for his all the way victory, adding rounds of 65, 64 and 67 to win by four over Brandt Snedeker who tried valiantly to bridge the gap throughout the course of the final round. Snedeker reduced the margin to three early in the round and again through 17 holes but by then it was all too late. Everything Snedeker did Mickelson matched and when Snedeker bogeyed his final hole Mickelson had cruised to victory.
Scott Piercy finished alone in 3rd position two shots behind Snedeker while Ryan Moore was one shot further back.
Mickelson said afterwards that despite two indifferent efforts to start the year at La Quinta and Torrey Pines that he felt his game was close to where it was late last year when he put together several very good tournaments. He worked with Butch Harmon and Dave Stockton earlier in the week and the results were there for all to see.
"Butch came into town Wednesday morning, and we spent an hour and 15 minutes on the range, and it was just a minor tweak, and all of a sudden the club is back on plane and I'm hitting it the way I was, said Mickelson. "Certainly tying for 37th and 50 something doesn't really indicate this kind of play coming the next week, I understand that, but it did not feel far off. I felt like I was ready to click."
In front of a crowd for the week of 520,000 Mickelson thrilled his many local fans with golf of the highest calibre. He fell two short of the current PGA Tour 72 hole record Tommy Armour 111 established when winning the Texas Open in 2003 but his main focus was on winning the tournament and hold off a determined effort by Snedeker.
Mickelson now heads to Pebble Beach for the AT&T National Pro Am Championship where he will attempt to defend the title he won last year.
Greg Chalmers finished the best of the Australians in 36th position, Jason Day was 57th and Aaron Baddeley was 65th.
