FORT WORTH, Texas (AP) ― Zach Johnson was so caught up in the emotion of another Colonial title and a victory in honor of his caddie’s late father that he forgot to properly remark his ball before his final putt.

Even with a two-stroke penalty, Johnson won by one over Jason Dufner and got to slip on the plaid jacket Sunday for his first victory since also winning at Hogan’s Alley two years ago.

“There’s a number of adjectives I’m calling myself right now. And lucky would be the biggest one,” Johnson said.

“Blessed would be another one, humbled would be another one. It’s an honor to put this jacket on once. ... I’m in shock I got it twice.”

Johnson moved his original ball mark out of the line of Dufner’s putt on the 18th green. But he never moved it back before his final 5-foot putt.

The penalty was assessed before he signed his scorecard, and Johnson’s 12-under 268 total was enough to edge Dufner, who finally faltered and closed with a 74.

Johnson had already shared celebratory hugs and kisses with his two young sons and done a winner’s television interview before caddie Damon Green, prompted by a rules official, asked the 2007 Masters champion if he had put his ball back in its original spot.

“First time it crossed my mind,” Johnson said. “It’s not going to be the last time.”

The victory came 10 days after Green’s 88-year old father died from stomach cancer. After Johnson’s runner-up finish at The Players Championship two weeks ago, the caddie drove to Pensacola, Florida, to see his father. But Damon Green was ready to get back on the course this week.
