Phil Mickelson failed to build on an impressive start at the Northern Trust Open to leave fellow American Scott McCarron three shots ahead of him after two rounds of the event at Riviera Country Club.
It's been an unimpressive start to the year for Mickelson, who has missed one cut and finished 42nd and 55th in his other two events, but the world's fifth-ranked player looked to be on his way to turning things around after an eight-under-par 63 gave him the lead after the first round.
Mickelson's momentum continued early in the second round when he sank a 28-footer on the first hole for an eagle that moved him to 10-under.
However, Mickelson immediately gave that shot back with a bogey at the par-four second hole. The rest of the round was also uneven as Mickelson had three more bogeys and a birdie to sign for a one-over 72.
At seven-under 135 through 36 holes, Mickelson is three shots behind leader McCarron, who also has struggled this year.
McCarron, who underwent elbow surgery in 2006 and missed the entire following season, shot a three-under 68, moving to 10-under 132 overall.
After missing the cut last week at the Pebble Beach National Pro-Am and not finishing better than 34th in his previous three events, McCarron finds himself two strokes ahead of three golfers as he seeks his first win since claiming the BellSouth Classic in 2001.
Steve Stricker (66), Tommy Armour III (67) both are two shots off the lead.
Joining Mickelson at seven-under are Englishman Luke Donald (69), Rory Sabbatini (67), Pat Perez (66), KJ Choi (69) and Geoff Ogilvy (67).
"Obviously, I've got to get things turned around," Mickelson said.
"This is the first time I'm in contention heading into the weekend and I'm excited about it."
