The 1989 Open Championship was the 118th Open Championship held 20–23 July at the Royal Troon Golf Club in Troon Scotland. Mark Calcavecchia won his only major championship in a playoff over Greg Norman and Wayne Grady. It was the first playoff at the Open in fourteen years and the first use off the four-hole aggregate playoff adopted in 1985. The playoff was formerly 18 holes the following day (and 36 holes prior to 1964).
