BOCA RATON, Fla. — Rocco Mediate birdied the 18th hole and finished with a 1-under par 71 to win the Allianz Championship on Sunday.

The Greensburg, Pa. native finished the tournament at 17-under 199 and became the 16th player to have a winning debut on the Champions Tour.

Mediate’s 4-foot birdie putt came after Tom Pernice Jr. missed a 5-footer at No. 18 that could have forced a playoff.

Mediate started the day with a three-shot lead, lost it by the 14th hole, but regained it when Pernice bogeyed the par-4 17th from a greenside bunker. Mediate protected that lead with a birdie on the par-5 closing hole.

“I’m ecstatic,” Mediate said. “I have been saying all week it’s never easy. It shouldn’t be easy. I was prepared to make that putt (at 18), but I didn’t have to.”

Pernice, who had a final-round 70, finished tied with Bernhard Langer (68) for second place.
