Jordan Spieth continued his run of dominance at the Hyundai Tournament of Champions on Saturday, posting an eight-under 65 that included an eagle at the par-5 18th hole to get to 24 under and extend his lead to five shots at the Plantation Course at Kapalua.
Ernie Els' tournament record of 31 under par, set in 2003, is within range for Spieth.
"I think it's a great goal to set, to try and set something to shoot for versus trying to look at behind you at who is coming up," Spieth told reporters in Hawaii. "Trying to get to 30 would be a fantastic number to set for tomorrow. That would be a place I've never been."
Brooks Koepka ascended six places and into second by shooting a 10-under 63, the best score of the day. His round featured 10 birdies, including six in a row on the front nine.
Patrick Reed, who was tied for second place after Friday, shot a six-under 67, dropping him to third at 18-under overall. He remains bogey-free through 54 holes.
Jimmy Walker made a significant move on Saturday, shooting a nine-under 64 to get to 14 under and tied with Rickie Fowler, Steven Bowditch and Kevin Kisner for sixth.
Reigning PGA Championship winner Jason Day shot a four-under 69, bringing him up one spot to tie for 20th overall.
