Back in 1971, a racehorse named Canonero II pulled a big surprise by winning the Kentucky Derby. Prior to the race almost no one was talking much about Canonero II. A few so-called experts suggested he might have an outside chance because he’d been racing in Venezuela. At times racehorses do well in the U.S. shortly after being shipped in from South America because the altitude change can have a positive effect. Prior to the race that seemed to be the only angle Canonero II had in his favor.
On Derby Day there was nothing in the Daily Racing Form to recommend that Canonero II should be considered anything but a long shot. There was literally no data on Canonero II at all. That’s because the information on his most recent races in South America hadn’t yet arrived in the U.S. The lines for Canonero II in the Daily Racing Form that usually have records showing how the racehorse has performed in the past simply stated: “Not Available.”
