new shooter
n.— «Sometimes, the Triple Crown horses are ambushed by a fresh new shooter in the Belmont. Stage Door Johnny peaked just at the right time to defeat Forward Pass in 1966. Coastal blossomed late and upset Spectacular Bid two years ago.» —“Belmont Stakes: The Third Jewel of the Triple Crown” by Andrew Beyer in Belmont, N.Y. Washington Post June 6, 1981.
