Pine Mountain, Ga. — Chris DiMarco made a 15-foot birdie putt on the 18th hole Sunday to tie David Duval, then won the Buick Challenge on the first playoff hole when Duval missed an 8-footer for par.
Duval, the defending tournament champion, closed with a brilliant 9-under-par 63 on the Mountain View course at Callaway Gardens, walking off with a one-stroke lead.
He then went to a television booth overlooking 18, where he watched DiMarco make the clutch putt with his unique claw grip to give both players a 21-under 267.
"I was expecting to be in a playoff," Duval said. "I didn't want to be in a playoff, but I was expecting it."
He had to work hard just to get that far, beginning the day six strokes behind third-round leader Joel Edwards.
DiMarco won the SEI Pennsylvania Classic last year against a much weaker field.
"Look at the field," DiMarco said, mentioning Duval, Vijay Singh and Davis Love III. "When I won last year, I beat some good players but not the big names. To do it against the big names is very special."
Bob Estes tied for third with Neal Lancaster at 269. Love struggled to a 71 and finished at 270.
Edwards struggled to a 74 and wound up five strokes back at 272 strokes.
