American golfer Hale Irwin has birdied the 18th hole to win the weather-plagued Senior PGA Championship by one stroke over Jay Haas in Louisville.
Irwin led after each round and finished at 8-under 276 to win the event for the fourth time.
He won it three years in a row starting in 1996.
Irwin, who will turn 59 on Thursday, was the oldest winner of the event since Pete Cooper won in 1976 at age 61.
