Who Am I ???

*I won exactly half of my lifetime starts, in fact I won half of my starts at two, half at three and half at four. *Each successive year I won more races, more stakes and bigger races than the previous year. *I raced on both dirt and the grass, but I much preferred one over the other. *I won one Derby and finished third in another Derby. *My wins had a five furlong spread between the shortest and the longest. *I was defeated by a Preakness winner and three different Breeders‘ Cup winners. *I won some big races, but the biggest was my final career win and my third to last start before retirement. *My eight stakes wins came at four different racetracks and three different distances. *You can keep New York, Belmont Park was the sight of my poorest lifetime performance. *My last two races were very disappointing, but I had solid excuses in those races. *Today I am a shuttle stallion, breeding in both the Northern and Southern Hemispheres.
