In a closely contested race, Sir Ivor finished third, beaten a short head and three quarters of a length by Royal Palace and Taj Dewan.

Sir Ivor returned in late September when he ran in the Prix Henry Delamarre at Longchamp in which he finished half a length second to Prince Sao, to whom he was conceding nine pounds.

Sir Ivor, whose best distance was probably 10 furlongs was outstayed by the favourite, Vaguely Noble, in the very soft ground who won by three lengths.

[6] Two weeks after his run in Paris, Sir Ivor appeared at Newmarket, where he won the Champion Stakes easily[3] by two and a half lengths from a field which included Taj Dewan.

Piggott held the colt up before producing a "furious stretch drive"[7] to lead in the last twenty yards and beat Czar Alexander, with the American Champion Male Turf Horse Fort Marcy in third.

Retired after his three-year-old racing season, Sir Ivor was sold to a syndicate to stand at stud at Claiborne Farm in Paris, Kentucky.
