Manatee stepped right up in class four weeks later but had to settle for fourth in the Grand Prix de Saint Cloud, beaten by three high-profile names; Treve, Flintshire and Dolniya. A break followed, before he was thrown into the deep end in the Prix de l’Arc de Triomphe in early October. Starting as one of the outsiders, Manatee finished 11 of the 17 runners, eased in the closing stages and beaten 7¼ lengths behind champion Golden Horn. Manatee’s next task was a test of stamina, as he went for the Prix Royal-Oak. The stayers’ classic was won by Vazirabad, who was followed home by Siljan’s Sage, Mille Et Mille, Cirrus des Aigles and Manatee, who was once more beaten 7¼ lengths by the winner.
