Patrick Reed had three eagle attempts Thursday and made the last one for an 8-under 65 and a one-shot lead over Jordan Spieth in the Hyundai Tournament of Champions.
Reed is the defending champion at Kapalua and has top 10s in his last six tournaments around the world.
Most of the attention was on Spieth, coming off a blockbuster year that included two majors.
Spieth and Reed were part of a five-way tie for the lead on the par-5 18th on the Plantation Course when Reed drilled a 3-wood onto the green and let the grain take it to 15 feet. He made the putt to cap off a 31 on the back nine.
Brandt Snedeker, J.B. Holmes and Danny Lee were at 67.
