Jon Rahm is on the verge of regaining world No 1 status after a third-round 65 put him in the lead at the Genesis Invitational.
Rahm picked up six birdies without a dropped shot to sit three shots clear at 15-under heading into Sunday’s final round in California.
A win at The Riviera Country Club would see the Spaniard eclipse Scottie Scheffler for the world No 1 ranking.
The American overtook Rory McIlroy for the top spot with victory at the WM Phoenix Open last week.
McIlroy fell out of contention on Saturday with a two-over 73.
Chasing Rahm is the overnight leader Max Homa, who was left to rue two late bogeys en route to carding a two-under 69.
The American duo of Keith Mitchell and Patrick Cantlay could also still threaten, opening their final rounds four and five shots back respectively.
Meanwhile, Tiger Woods had his best round of the tournament, carding a four-under 67 to head into Sunday in a positive frame of mind.
