1929 Open Championship

The 1929 Open Championship was the 64th Open Championship, held 8–10 May at Muirfield in Gullane, East Lothian, Scotland. Walter Hagen successfully defended his 1928 title, six strokes ahead of runner-up Johnny Farrell. It was Hagen's fourth win at the Open and his eleventh and final major title.

Qualifying took place on 6–7 May. Entries played 18 holes at Muirfield and 18 holes at the number 1 course Gullane. The top 100 and ties qualified. The qualifying score was 162 and 109 players qualified. Leo Diegel led the qualifiers on 144. There was a change in the cut rule. To make the cut players would need to be within 14 strokes of the leader after 36 holes but there was to be a minimum of 60 left in the field.

Percy Alliss held the lead after the first round with a 69, while Leo Diegel matched that score in the second round to take the 36-hole lead. After a first-round 75, defending champion Hagen recorded an Open Championship record 67 in the second round on Thursday and was two back of Diegel. Scores on Friday over the final two rounds soared. Diegel shot 82 in the third round, with Alliss and Abe Mitchell at 76 and 78, respectively. Hagen, meanwhile, finished with two rounds of 75, giving him 292 total. Diegel was a shot behind runner-up Farrell in third place, while Alliss and Mitchell shared fourth at 300.

Hagen, age 36, played the tournament just twice more, in 1933 and 1937. Six-time champion Harry Vardon, age 59, played the Open for the final time and missed the cut. Similar to 1928, this Open was played earlier than usual, in early May.
