Johnson has 1st-round lead at Colonial after 64
By STEPHEN HAWKINS
FORT WORTH, Texas (AP) Zach Johnson shot a bogey-free 6-under 64 on Thursday to take a one-stroke lead after the first round of the Colonial.
Johnson opened his round with a 40-foot birdie putt on his first hole, No. 10. After blasting from a greenside bunker at No. 12 to save par, he had four birdies in a row on a day when gusty wind whipped through the big oaks lining the fairways at Hogan's Alley.
Even though he has made the cut in all 12 tournaments he has played this season, Johnson hasn't won since the Colonial two years ago.
Jason Dufner, the Byron Nelson Championship winner Sunday, was a stroke back along with PGA Tour rookie Harris English, Tom Gillis and Kyle Reifers.
