Royal Cinque Ports had been planned as the location for the Open Championship in 1915, but in early in that year it was decided that there would be no championships during the remainder of World War I; the next Open Championship after the war would be held at Royal Cinque Ports.[6] Although the war was over in November 1918, it was decided that there would be no championship in 1919.[7] During the war, six of the greens were involved in a scheme to build a rifle range. This raised fears about the state of the course, but in late 1919 it was decided that there would be no difficulty in getting the course ready for the 1920 championship.[8]
Qualification for the professionals took place the week before on 23 and 24 June at Burhill and Saint George's Hill in Surrey; the leading 72 players and ties qualified.[9][10]Abe Mitchell led the field at 139; three tied on the qualifying score of 159 and 74 professionals advanced.[10][11] The amateurs qualified separately, playing 36 holes on 23 June at Sandwich. Eight places were allotted to the amateurs with Cyril Tolley, the Amateur Champion, given an automatic entry.[12] Prize money was increased sixty per cent to £200 with a winner's share of £75; the winner also received a gold medal valued at £25.
Herd and Ted Ray, the 1912 winner, shared the first round lead at 72 on Wednesday morning. Both faltered in the afternoon's second round while Abe Mitchell shot a 73 for a 147 to open up a six-stroke lead over Herd and Jim Barnes. Ray was eight back, Len Holland eleven behind, while Duncan was thirteen back after consecutive rounds of 80 for 160.[13]
Duncan played himself back into contention with a 71 in the third round on Thursday morning. Mitchell began that round with three bogeys, made a seven at the 5th hole, and finished with an 84. After 54 holes, Holland was at 229 and led by one over Herd and Barnes, with Mitchell, Duncan, and Syd Wingate one behind in fourth. Duncan carded a final round 72 for 303, while Holland and Barnes both shot 79 for a 308 and 309, respectively. Mitchell rebounded with a 76 which left him at 307. Only Herd could match Duncan's score, but he found trouble on the 16th and settled for 305, two strokes back of Duncan.
Six-time and defending champion Harry Vardon, age 50, finished at 318, 15 strokes back in a tie for 14th place.
Two future champions from the United States, Walter Hagen and Scottish-born Tommy Armour, both made their Open Championship debuts this year and both finished at 329, 26 strokes back in a tie for 53rd. Armour was an amateur at the time.
This was the second and final Open Championship held at Royal Cinque Ports, which also hosted in 1909. Further Open Championships at Royal Cinque Ports were planned for 1938 and 1949. In both cases the course was flooded during the previous winter prior and the venue was moved to
Royal St George's. Thus, only one of the four Opens planned for Royal Cinque Ports actually took place in the year originally intended. Near the English Channel, the course is directly south of Royal St George's, which became the sole Open venue in southern England in the course rota. An exception was in 1932, when Prince's Golf Club hosted its only Open, won by Gene Sarazen. All three courses are adjacent, with Prince's the furthest north.
