SCOTTSDALE, Ariz. -- Phil Mickelson quickly shook off that double bogey he made on the 18th hole Friday with a 20-footer for birdie on his first hole of the third round.
So Mickelson is now 18 under and owning a five-stroke lead but the rest of the leaderboard is quickly changing. Padraig Harrington is currently his nearest challenger after making the turn in 30 with five birdies on the front nine, including three straight to open the round.
Troy Matteson and Robert Garrigus, who lives about 25 minutes away from Scottsdale, both birdied the third and fourth holes to get into a big group at 12 under. Also at that number are Ryan Moore, Brandt Snedker, Keegan Bradley and Bill Haas, who three-putted from the fringe at the first hole.
