Hideki Matsuyama from Japan and American Jimmy Walker will take a two-stroke lead into the final round of the Hyundai Tournament of Champions, the first 2015 event on the US PGA Tour.
Matsuyama carded a third round 66 at the Kapalua Resort and Walker shot 67 for the second time in three days as the limited field, in the main, continued to take advantage of decent scoring conditions at Kapalua, Hawaii.
Walker had looked like turning the tournament into a procession for a spell on Sunday when he made four birdies in a six-hole run to take a two-shot lead into the back-nine.
The Ryder Cup rookie made a fifth birdie at the 10th but his round stalled, and it was only a two-putt birdie at the last hole that ensured a tie for top spot with 18 holes remaining.
And that was because of Matsuyama's flying finish as he matched the best score of the week.
Matsuyama started the day badly, bogeying the opening hole, but he had two birdie runs which made all the difference, starting with four in five holes from the fifth.
He went hunting birdies again from the 13th, picking up shots on three successive holes, and then a lovely chip to two feet on the par-five closing hole made it eight for the day.
"I like the views and so I like the course," a smiling Matsuyama said. "I haven't played a golf course that has so much undulation, up and downs and where the views are so beautiful.
"Obviously this is my first time here, so I don't know if the wind this week has been hard or it's been light wind. I'm not sure. But if the wind can stay like this, I think I'll be okay tomorrow."
Patrick Reed sits two shots off the pace after a round of 68 - he made five birdies and, for the second time in three rounds, avoided any dropped shots.
He is tied for third with Korea's Sang-Moon Bae, who also had five birdies but dropped a shot at the seventh after being in a tie for the lead at halfway.
Brendon Todd and Russell Henley are one stroke further back on -14 with Bubba Watson in a group on 12-under after a 68 which included six birdies.
But it was a bad day for defending champion Zach Johnson, who had been in a tie for the halfway lead, as he struggled to a level-par 73.
Johnson opened with four pars but then made double bogey at the par-five fifth and four birdies over the rest of the round were not enough to keep him close heading into Monday's final round.
And the anticipated charges from Jason Day and Matt Kuchar also failed to materialise, with Day carding 71 to sit eight shots off the pace and Kuchar slumping to a 74 that left him in a lowly tie for 20th.
