Hold everything ... Just when you thought Zach Johnson was going to win, Troy Matteson buries a 60-foot putt for eagle on the par-5 17th hole. Johnson, who made par on the 18th for a final-round 65, and Matteson are now tied at 20 under. Johnson just missed a 15-footer from the fringe on 18 for birdie. Matteson needs a birdie on 18 to win. He's in the right rough off the tee. Interestingly, a young fan in the gallery picked up Matteson's ball in the right rough, thinking it was a souvenir. Matteson got to place the ball back to where it was presumed to have stopped via rule 18-1. Matteson hit a low, running punch shot through the trees to within 15 feet of the hole. He'll have a putt to win. A two-putt to tie Johnson for a playoff. Stay tuned. ...
