OZONE PARK, N.Y. – Geno, winner of the Great White Way division of the New York Stallion Series, and Happy Medium, a promising older sprinter who finished third in the Grade 3 Toboggan, had to be euthanized last week in separate training incidents over the Belmont Park training track.
Geno, a 3-year-old son of Big Brown, was euthanized Saturday after a gallop over the training track, according to trainer David Donk.
