English, Palmer co-lead after Round 3 at Tournament of Champions

Harris English and Ryan Palmer share a one-shot lead at 21-under par heading into the final round of the Tournament of Champions.

English, who has held a piece of the top spot at the end of all three rounds, posted a 66 in Round 3. He was in cruise control for most of Saturday until the par-5th 18th, when English pulled his approach shot into the penalty area.

However, a nearby marshal quickly located his ball, and English managed to salvage a par by draining an eight-foot putt to secure his spot in Sunday's final pairing.

"(I'm) extremely satisfied," English said of his performance. "Normally Saturday is my toughest day out here on the PGA Tour, kind of a weird day of in between making the cut and finishing on Sunday and I felt like I played really well today, stuck to my strategy, executed really well, and stayed patient."

Palmer was in chase mode all day, trailing English by two entering the round. He tallied nine birdies - six of which came on the back nine - while not registering a bogey for a 9-under 65, the lowest score of the week so far.

The duo lead world No. 7 Collin Morikawa, who shot 65 on Saturday. He and Daniel Berger will form the penultimate pairing during Round 4.

Here's the top of the leaderboard with 18 holes remaining:

Justin Thomas shot 68 with an eagle - which was erased with a double-bogey on the following hole - to fall into a tie for fifth. He'll play alongside Sungjae Im on Sunday.

Round 4 from Kapalua begins at 12:30 p.m. ET, with the final pairing teeing off at 3:50 p.m. Here's the broadcast schedule for Sunday:
