Thirty-six years have come and gone since the last Triple Crown winner.
Tonight, California Chrome will try to break the streak at Belmont Park. The horse, once considered an underdog, galloped to decisive victories at both the Kentucky Derby and the Preakness. But Chrome and jockey Victor Espinoza face a crowded field with plenty of competitors that chose to forgo one of the two previous races in an effort to remain fresher. Co-owner Steve Coburn dislikes the cherry-picking approach, but he says he is focused on Chrome's race.
"I think triple means three," he told USA Today. "It's all or nothing."
While Affirmed was the most recent Triple Crown winner, in 1978, the benchmark is still Secretariat, the "miracle horse" that won in 1973.
