The 1991 Open Championship was the 120th Open Championship, held from 18–21 July at Royal Birkdale Golf Club in Southport, England. Ian Baker-Finch won his only major championship, two strokes ahead of runner-up Mike Harwood. Baker-Finch was two-over after two rounds in a tie for 28th place, then was ten-under on the weekend. His 66 on Sunday was bolstered by a 29 on the front nine, with birdies on five of the first seven holes. The cut at 148 (+8) included those within ten strokes of the lead, which resulted in a record 113 players on the weekend, nearly three-quarters of the field.
