Mill Reef
My Swallow's three-year-old season began with a win against moderate opposition in the Usher Stakes over seven furlongs at Kempton Park Racecourse in April. He then contested an exceptionally strong renewal of the 2000 Guineas over the Rowley Mile course at Newmarket Racecourse. He was opposed again by Mill Reef, who had been unbeaten since the Prix Robert Papin, winning the Gimcrack Stakes, Dewhurst Stakes and Greenham Stakes. My Swallow was ridden by Frankie Durr, having been rejected by Piggott in favour of the Vincent O'Brien-trained Minsky, a full-brother of Nijinsky. Also in the field was Brigadier Gerard, undefeated in four races including the Middle Park Stakes. Mill Reef started favourite at 6/4, with My Swallow on 2/1 and Brigadier Gerard on 11/2. My Swallow led from the start before being challenged by Mill Reef a quarter of a mile from the finish and the two colts raced side by side throughout the closing stages. Neither of them, however, had any response when Brigadier Gerard challenged along the rail. Brigadier Gerard won easily by three lengths, with Mill Reef beating My Swallow by three-quarters of a length for second.
