And he matched or challenged tournament and PGA Tour scoring records every round:
- His 60 in Round 1 matched the tournament 18-hole scoring record, and his 256 total matched the tournament's 72-hole record.
- Mickelson's opening 60 was the 27th round of 60 in PGA Tour history, and he became just the second golfer with two rounds of 60 in PGA Tour events. His birdie putt for 59 on the 18th hole lipped out.
- Mickelson finished the second round at 125, one stroke off the tour's all-time record for the first 36 holes (Pat Perez and David Toms share the record of 124).
- Mickelson finished the third round at 189, one stroke off the tour's all-time record for the first 54 holes (Steve Stricker holds the record at 188).
- And Mickelson's 256 finishing total is tied for second-best ever in a 72-hole tournament. Tommy Armour III holds that record at 254. Mickelson is tied for second place with Mark Calcavecchia, whose 254 also happened at the Phoenix Open; and Russell Henley, whose 254 happened at this year's Sony Open.
As noted, it's the 41st PGA Tour win for Mickelson, one ahead of Cary Middlecoff and four behind Walter Hagen on the all-time wins list.
It's unlikely Mickelson will catch Hagen this year, however - he hasn't won more than one tournament in a PGA Tour season since 2009, and has never won as many five times in a PGA Tour season (which is what he'll have to do to catch Hagen in 2013).
