At Doncaster in September, Bahram started 4/11 favourite for the St. Leger Stakes in his bid to become the first winner of the traditional Triple Crown since Rock Sand in 1903 (Pommern, Gay Crusader and Gainsborough had won wartime "Triple Crowns" but these included substitute races run at Newmarket). Since Rock Sand, four colts had attempted the feat but St. Amant (sixth in 1904), Minoru (4th in 1909), Manna (tenth in 1925) and Cameronian (tenth and last in 1931) had all been well-beaten at Doncaster. He was ridden by Charlie Smirke, Fox having sustained serious injuries in a fall the previous day. Bahram won very easily by five lengths from Solar Ray, with Buckleigh a further three lengths away in third. After the race Smirke claimed that Bahram could have won carrying "12 Stone and two riders".
