The late Allen Jerkens trained Beau Purple when he upset the mighty Kelso three times in the 1960s. He saddled Onion when he shocked Secretariat in the Whitney Invitational in 1973 and got the best of “Big Red” once more that year with Prove Out in the Woodward Stakes. Yet, when Jerkens was asked to name the top horse he conditioned, he immediately responded with Sky Beauty. “She’s in front of all of them,” he told the Daily Racing Form, adding, “She was sheer class.”
