Zach Johnson Up by Three in Tournament of Champions

Zach Johnson followed up his opening 6-under 67 with a stellar 66 to take a three-stroke lead through 36 holes of the Hyundai Tournament of Champions. The $5.7 million PGA Tour event began Friday at the Plantation Course at Kapalua on Maui, Hi.

After posting an eagle, seven birdies and three bogeys in the first round, the 37-year-old Iowan - a 10-time Tour winner - carded four birdies on the front nine and three more on the back to reach 13-under 133, three strokes ahead of Matt Kuchar (68), Jordan Spieth (70) and defending champion Dustin Johnson (66).

"The more I get my feet here, the more I walk these grounds, the more comfortable I become . . . I'm comfortable with how I'm attacking, and I'm making putts - most of them," Zach Johnson told reporters.

Spieth began the day tied for the 18-hole lead with Michael Thompson, Chris Kirk and Webb Simpson. Though he wasn't as hot as he was Friday, when he fired seven birdies for a 66, the 20-year-old managed four more birdies and his first dropped shot of the tournament - a bogey on the par-4 seventh - to stay within reach Zach Johnson heading into the last 36 holes.

"All in all, I'm in good position going into the (final two rounds)," said Spieth, the 2013 PGA Tour Rookie of the Year.
