Bred by Harry Giddings at his Cedar Grove Stud in Oakville, Ontario, his sire, Bassetlaw, was a son of the outstanding runner and nine-time Leading sire in Great Britain & Ireland, St. Simon.
Racing Hall of Fame inductee and a four-time Leading sire in North America.
As a yearling, he severely injured himself when he caught a hoof between the rails of a fence and as a result was unable to race until age three.
Raced at Woodbine Park Race Course in Toronto, Ontario, St. Bass won the King's Plate by six-lengths in a time of 2:08 4/5 for 11⁄4 miles, beating the existing record by an exceptional 1 3/5 seconds.
St. Bass would be the first of four King's Plate winners for owner/breeder Harry Giddings and the first of a record eight wins as a trainer for his son, Harry Jr. Three days after winning the King's Plate, St. Bass and jockey Dugan won the Breeders' Stakes and on June 21, the colt won the Dominion Plate at the Hamilton, Ontario racetrack.
