Dufner has 1-stroke lead over Johnson at Colonial updated 5:03 p.m. FORT WORTH, Texas (AP) - Jason Dufner matched playing partner Zach Johnson's birdie putt on the 17th hole Saturday and finished with a 4-under 66 for a one-stroke lead in the Colonial. The Byron Nelson Championship winner last week, Dufner saved par on the final hole after a wayward tee shot and finished three rounds at 15-under 195. Johnson was second after a 65, and Tom Gillis a distant third at 7 under. Dufner is trying to win for the third time in five weeks, and join Ben Hogan as the only players to win both PGA Tour events in the Dallas-Fort Worth area in the same year. When Hogan did it in 1946, the events weren't played in consecutive weeks.
