Zach Johnson made a quadruple-bogey 8 on his second hole Thursday and still managed to shoot a 67 in the Honda Classic.
Tiger Woods had good birdie chances on his opening four holes and couldn't break par.
Johnson wound up two shots behind co-leaders William McGirt and Rory Sabbatini among the early starters at PGA National. He put two shots into the water on the 11th hole and made his 8. The 2007 Masters champion went on to make seven birdies on a cloudy morning in South Florida.
Sabbatini and McGirt were tied at 65.
Woods, playing for the first time in a month, made only two birdies in his round of 71. He likely will be just outside the cut line going into the second round Friday.
