Gary Woodland holds a three-shot lead going into the final day of the Sentry Tournament of Champions.
The American fired a five-under 68 on the third day in Hawaii to keep his place at the top of the leaderboard, with Rory McIlroy taking sole possession of second place.
Woodland's one blemish came with a bogey on the par-four 12th, but he took hold of the lead after holing a 64-yard putt for eagle on the par-five 15th.
McIlroy - making his debut at the event which consists only of PGA Tour winners from the previous calendar year - matched Woodland's 68 after carding three straight birdies through holes four to six and picking up another shot on the ninth.
The Northern Irishman got up and down on the 14th to briefly tie for the lead, before closing with four straight pars to get to 14 under and keep himself in contention to overtake Woodland over the last 18 holes on the Plantation Course at Kapalua.
Marc Leishman also carded a five-under 68 to move into third place on 13 under. After two birdies on the front nine, the Australian picked up four shots after the turn including a 27-foot birdie on the 12th.
World number one Brooks Koepka tumbled down the standings with a 73, an eagle on the ninth cancelled out by three bogeys, and lies in joint 29th.
Ian Poulter dropped into joint 13th after firing a 73, while fellow Englishman Paul Casey tied for the low round of the day on 68 to move into joint 11th.
