Even after a hearty handshake from the tournament host and a shiny trophy an arm's length away from, Every summed up this wild day with just the right words.
"I ... I ... I can't believe I won," he said. "I just ... I really can't."
The tee shot that he feared might be out-of-bounds on No. 9 somehow bounced along a cart path and led to an unlikely birdie. He surged to a three-shot lead when Scott's touch with the putter vanished. Even with two bogeys on the last three holes he missed a 4-foot par putt on the 18th Every still closed with a 2-under 70.
The last bogey made him sweat out the finish. Keegan Bradley, who birdied the 16th and 17th holes, had a 30-foot birdie putt on the 18th that would have forced a playoff.
Every finished at 13-under 275, one shot ahead of Bradley, who needed two late birdies for a 72. Scott was third.
In his 92nd start as a pro on the PGA Tour, Every finally won at just the right time and just the right place.
