The former US PGA champion, starting on the back nine, rallied through holes four to nine to card a 64 on the Tournament Course and join Jerry Kelly, Jeff Overton and Anirban Lahiri on eight under.

Overton enjoyed a run of five successive birdies on the Tournament Course while Kelly struck five birdies and two eagles on the La Quinta course. India's Lahiri carded eight birdies in his faultless round on La Quinta.

Those playing on the Stadium Course found life much tougher, with Canada's Adam Hadwin performing best with his six-under 66 leaving him tied eighth.

Phil Mickelson is well back on four Under after his 68 on La Quinta.
