JJ Spaun shot a five-under-par 65 to move into the lead ahead of the final round of the Sony Open in Honolulu.
Spaun's best score of the tournament puts him at 13 under but he has plenty of pursuers within range.
He's ahead of second-round co-leader Patrick Fishburn, Eric Cole and Germany's Stephan Jaeger by one stroke. Jaeger, after a 62, had the best score of the day with birdies on six of the final 10 holes.
Spaun, appearing in his 219th PGA Tour event, is seeking his second victory. The first came in the 2022 Texas Open. He was clean for most of the day, scattering five birdies over the first 14 holes before alternating bogeys and birdies on the last four.
LEADERBOARD
Fishburn began the round with two birdies, but played the back nine two over.
Keegan Bradley, Harry Hall and Canadian Nick Taylor are among a cluster of six golfers tied for fifth at 11 under.
Denny McCarthy, who was even with Fishburn entering the round, slipped to a tie for 16th after shooting 71.
Japan's Kensei Hirata, who had a 63 for Friday's best round, is also in that group at nine under after posting a 70 on Saturday.
There are 14 golfers within three shots of Spaun and 27 within five strokes of the top spot.
