Maui, HI (SportsNetwork.com) - Zach Johnson fired a 7-under 66 on Saturday to claim a 3-stroke lead after two rounds at the Hyundai Tournament of Champions.
The 10-time winner on the PGA Tour finished 36 holes on the Plantation Course at Kapalua Resort at 13-under-par 133.
"I don't know how many years I've been here. This is seven or eight probably and I've had maybe one or two decent finishes, but nothing so spectacular," Johnson said. "The more I get my feet here walking these grounds, I think the more comfortable I become."
Defending champion Dustin Johnson also shot 66 to jump into a share of second place with Jordan Spieth (70) and Matt Kuchar (68) at 10-under.
Michael Thompson (71) and Webb Simpson (71) are tied for fifth at 9-under, while Kevin Streelman (71) and Ryan Moore (71) occupied seventh at minus-8.
No one was able to meet the four overnight leaders -- Spieth, Simpson, Thompson and Chris Kirk -- at 7-under until Gary Woodland caught fire with three birdies and an eagle over a five-hole stretch from the ninth.
Dustin Johnson and Zach Johnson would eventually make it a seven-way tie at 7- under before Dustin Johnson pulled ahead of the pack when he stuck his tee shot at the par-3 eighth to within six feet and converted his birdie effort to move to minus-8.
That was Johnson's fifth birdie in six holes. He started the streak with a 21- foot putt at the third, and also added another lengthy putt from 27 feet at the seventh.
Spieth joined Johnson atop the leaderboard with a 12-foot birdie at the fourth, but Johnson stayed hot and rolled in a short birdie at the ninth to again claim the outright lead at 9-under.
Spieth answered with a 2-putt birdie at the fifth to again claim a share of first place.
The duo was joined at 9-under by Zach Johnson, who made his third birdie of the round with a 28-foot putt at the seventh.
Dustin Johnson then missed the green at the par-3 11th en route to a bogey, dropping him a shot off the pace.
Zach Johnson continued to go in the right direction when he poured in a putt from beyond 23 feet for his third straight birdie at the eighth to claim the outright lead at 10-under.
That advantage rose to two strokes after Spieth found a greenside bunker with his second shot at the seventh and could not get up and down for par, dropping him to minus-8.
Thompson moved within a shot of Johnson with a birdie at the eighth, but Johnson quickly regained his 2-stroke cushion with a 3-foot birdie at the 10th.
After Johnson and Thompson again traded birdies at the 12th and ninth, respectively, Thompson tripped to bogey at the 10th to fall to 9-under and hand Johnson a 3-stroke lead.
Johnson's lead was never threatened from there, as he reached 13-under with a birdie at the 14th and closed with four straight pars.
"Looking back on it, I just think about the par-5s. I parred every one of them," said Johnson. "I had a 3-putt on one of them for par, which can happen. A couple missed opportunities."
NOTES: Zach Johnson's 10 career PGA Tour victories are the most of any player in the field ... Kirk carded a 2-over 75 on Saturday to fall into a share of 13th place at 5-under 141 ... Thirteen players are making their debut at this event, including Spieth, last season's PGA Tour Rookie of the Year.
