Who Am I ???

*I finished first in seven out of twenty five lifetime starts over my four-year racing career. *My three biggest victories came within a span of just eight weeks. *I was bred in Kentucky and owned by a successful Chicago businessman. *I was ridden by a total of eight jockeys and had a different rider for each stakes win. *My Run for the Roses ended in a middle of the pack finish. *I never won a Triple Crown race, but I did beat the Preakness and Belmont winners. *I had two trainers, one was an American and the other came from the land of the Beatles. *All of my four stakes wins came in the same season, and three of them were of the grade 1 variety. *In my best season, I won six times out of thirteen starts. *My first grade 1 win was won as a longshot, in my last grade 1 win, I was an odds-on favorite. *I raced at twelve different tracks in my career and in distances ranging from five furlongs to a mile and a half.
