won the U.S. Triple Crown in 1941. He also won the Lawrence Realization Stakes and the Travers Stakes that year; Whirlaway is the only horse ever to win both the Triple Crown and the Travers, sometimes referred to as a "superfecta". He was voted the Horse of the Year in 1941, beating Alsab by 96 votes to 91 in a poll conducted by the Turf and Sport Digest magazine. A year later, Whirlaway repeated his win in the poll, beating Alsab with 76 votes to his rival's 45. Arcaro was the sole rider for Whirlaway in all of his 3-year-old victories, but dismounted for most of the 1942 season, when he served a long suspension for racing infractions. Jockey George Woolf took the reins for the majority of the 1942 season. In a major upset on July 4, 1942 at Empire City Race Track, Whirlaway ran second to Tola Rose who easily won by four lengths in track record time. On July 15, Whirlaway broke the Suffolk Downs track record for a mile and one-eighth with a time of 1:48 1/5 in winning the Massachusetts Handicap. Whirlaway and Alsab continued their 1941 rivalry through 1942. On September 19, 1942, Alsab defeated the Triple Crown champion in a match race at Narragansett Park in Pawtucket, Rhode Island. Although Whirlaway closed strongly through the stretch, Alsab lasted by a nose as both horses flew home through the stretch run. Whirlaway was named Horse of the Year for 1942 after defeating Alsab in a subsequent race and having 12 wins for the year to Alsab's 9. Woolf, who had previously won the Pimlico Special in 1938 on Seabiscuit and in 1940 on Challedon, rode the 1941 Triple Crown winner at a leisurely pace during the 1942 Pimlico Special in a walkover victory. No opponent had been found to challenge Whirlaway for the race. On December 12, more than twenty thousand people turned out to watch Whirlaway win the inaugural Louisiana Handicap at the Fair Grounds Race Course. The newly formed Thoroughbred Racing Association staged this event as a war-relief effort. Whirlaway entered stud at Calumet Farm in the spring of 1944 at age six. Among his best offspring were Scattered (winner of the Coaching Club American Oaks); Whirl Some (Selima Stakes), Dart By (All American Handicap) and Whirling Bat (winner of the 1951 Louisiana Derby). In August 1950, Calumet Farm leased Whirlaway to
