Zach Johnson won a tournament for the first time in two years when he retained his Colonial title, pulling ahead of the field when Jason Dufner faltered.
Johnson was assessed a two-stroke penalty for failing to replace his ball to its original position after marking it on the 18th hole. That left him with a 2-over 72 and a one-stroke victory. “I’m going to focus on the positives, because I hit a really solid putt and it’s a good thing I made it,” Johnson said. “No harm, no foul. It was my fault.” Johnson moved his original ball mark out of the line of Dufner’s putt on the 18th green. But he forgot to move it back before his final 5-foot putt.
