KAPALUA, Hawaii, Jan. 4 (UPI) -- Zach Johnson
's 7-under-par 66 Saturday put him three strokes ahead after two rounds of the Hyundai Tournament of Champions in Hawaii.
Johnson, seeking his 11th PGA Tour win, finished with a 36-hole total of 13-under-par 133 on the Plantation Course at Kapalua Resort.
The 37-year-old American birdied 4-of-5 holes to grab the lead at 10-under and cruised from there in a rare strong showing for him at Kapalua.
"I don't know how many years I've been here," he said. "This is seven or eight probably, and I've had maybe one or two decent finishes, but nothing so spectacular."
Also firing a 66 Saturday was Dustin Johnson, who forged a second-round tie with Jordan Spieth (70) and Matt Kuchar (68) at 10-under.
Knotted for third one shot further back were Michael Thompson (71) and Webb Simpson (71).
Ryan Moore (71) and Kevin Streelman (71) followed in seventh at minus-8.
