The colt was brought back in distance for the Withers Stakes over one mile on May 27. He was made 1/2 favorite, but despite finishing strongly he failed to catch Rosemont and was beaten by one and a half lengths. In the Belmont Stakes over one and a half miles on June 8, Omaha started 7/10 favorite over Rosemont and Firethorn. Racing on a sloppy track, he was towards the rear in the early stages and entered the stretch covered in mud. He then produced "one of his famous stretch drives" to win by a length and a half from Firethorn, with a further eight lengths back to Rosemont in third.
