Sudden-death playoffs are those that continue until someone wins a hole. Here are the longest sudden-death playoffs in PGA Tour history:
11 holes
- 1949 Motor City Open: Cary Middlecoff and Lloyd Mangrum
8 holes
- 1965 Azalea Open: Dick Hart def. Phil Rodgers
- 1978 Greater Milwaukee Open: Lee Elder def. Lee Trevino
- 1981 Quad Cities Open: Dave Barr def. Woody Blackburn, Dan Halldorson, Frank Conner, Victor Regalado
- 1983 Phoenix Open: Bob Gilder def. Rex Caldwell, Johnny Miller, Mark O'Meara
You might have noticed that a winner isn't indicated in the 11-hole Middlecoff-Mangrum playoff. That's because both players won. After 11 holes, by mutual agreement, the playoff was halted and Middlecoff and Mangrum were declared co-winners.
