Graeme McDowell remains on course for victory at the World Golf Challenge after a solid third round at Thousand Oaks.
The Northern Irishman soared to the top of the leaderboard on Saturday with a six-under 66 and heads into Monday's final day two clear at the top after following up with a 68.
It was a bogey-free round from the European Ryder Cup star and also included four birdies as he moved to 13 under for the tournament.
Keegan Bradley, in the news recently for his vocal defence of the endangered belly-putting technique, sits second on 11 under after signing for a 67 - the joint best round of the day alongside Bubba Watson.
He made six birdies but dropped a shot at the par-four ninth.
England's Ian Poulter failed to crack 70 for the third time in a row and is way off the pace at even par.
