Zach Johnson putted for birdie on every hole and made seven of them Saturday for a 6-under 67 that put him in a four-way tie for the lead after two rounds of the Hyundai Tournament of Champions.
Johnson was halfway home to becoming the first repeat winner at Kapalua who wasn't from Australia — Stuart Appleby and Geoff Ogilvy were the others. But not only is the first PGA Tour event of the year only through 36 holes, it's extraordinarily crowded.
Jimmy Walker dropped a stroke late and shot 67. Russell Henley got off to a sluggish start before a solid back nine for a 70. And Bae Sang-Moon closed with eight straight pars for a 69.
They joined Johnson at 11-under 135.
Five other players were one shot back.
