Here's a quote by Prado's agent and I do not detect much confidence by statement.
Bob Frieze, Prado's agent, said it was "a tough decision."
"We went back and forth, back and forth," Frieze said from Keeneland, where Prado is currently riding. "We won on Adriano in the Lane's End before we rode the other two. We felt obligated toward Graham. We had told Graham to let Edgar work the horse first, then we'd make a decision."
