World number three Justin Thomas made two late birdies to maintain his one-shot lead going in to the final round at the Zozo Championship in California.
The American birdied his opening two holes but low scores from the chasing pack saw Thomas overtaken at the top.
Birdies at 16 and 17 gave him a five-under 67 and a slim lead over world number two Jon Rahm, who shot 63.
England's Matthew Fitzpatrick also fired a 67 to sit four shots back but Tyrrell Hatton slumped to a 76.
Hatton had gone into the third round three shots behind Thomas but fell out of contention with a four-over round on a day of a good scoring.
Justin Rose continued his improved form since golf re-started after the shutdown for the coronavirus pandemic to sit 31st while Rory McIlroy shot a five-under 67 to lie in a share of 36th.
