Justin Thomas fired a six-under 67 for the third day running to take a narrow lead in to the final round of the SBS Tournament of Champions in Hawaii.
Thomas sits two shots ahead of Hideki Matsuyama, looking for his fifth worldwide win in six starts, with overnight joint-leader Ryan Moore a further two strokes adrift.
Three bogeys on the back nine leaves Patrick Reed six back on 12 under, while defending champion Jordan Spieth birdied three of his final four holes to lift him inside the top 20.
Walker drained a long-range birdie at the first and Reed picked up a shot at the third to briefly make it a four-way tie at the top, only for Thomas to move ahead with a hat-trick of gains from the third.
Thomas slipped back when he failed to get up-and-down from the rough to save par at the seventh, but stayed ahead thanks to Reed three-putting the 11th.
After Moore holed a 20-footer at the same hole, he and Thomas exchanged birdies at the next to move two clear of the chasing pack.
Matsuyama surged up the leaderboard by following a chip-in birdie at the 14th with another gain at the next, as Thomas eagled the driveable 14th to go in to a two-shot lead.
A final-hole birdie from Matsuyama closed a joint-low round-of-the-day 66 to halve Thomas' cushion, only for the American to tap-in for a gain of his own and restore his advantage.
Moore shares third spot with PGA Champion Jimmy Walker and William McGirt, who matched Matsuyama's 66, with Brendan Steele another stroke behind on 11 under.
World No 1 Jason Day failed to capitalise on a fast start, birdieing three of his first six holes on his way to a three-under 70, leaving him tied-13th.
