Drosselmeyer, with veteran jockey Mike Smith aboard, won Saturday's Belmont Stakes in New York.
The horse did not qualify for the Kentucky Derby. But its owner, WinStar Farms, also owns derby winner Super Saver.
Fly Down finished second, First Dude was third.
Ice Box, the favorite at 9-5, finished sixth. Drosselmeyer went off at 13-1.
