In the 1973 film "The Sting", what is the name of the horse that boss Doyle Lonnegan bet on in the last race?

"The Sting" is a 1973 American crime-caper film set in September 1936, involving a complicated plot by two professional grifters (Paul Newman and Robert Redford) to con a mob boss (Robert Shaw). The premise of the con is to make him part with his money in a way that he will not possibly rationally demand it back and then present circumstances where even if he’d wanted to do it irrationally, he couldn’t. He must bet to win and not to place (i.e., finish second).

Armed with a tip from a guy named Harmon to "'place' the money on Lucky Dan", Lonnegan makes the $500,000 bet at Shaw's parlor on Lucky Dan to win. As the race begins, Harmon arrives and expresses shock at Lonnegan's bet: when he said "place it" he meant, literally, that Lucky Dan would "place" (i.e., finish second). In a panic, Lonnegan rushes to the teller window and demands his money back.

The film was directed by George Roy Hill, who had directed Newman and Redford in the western "Butch Cassidy and the Sundance Kid". Created by screenwriter David S. Ward, the story for "the Sting" was inspired by real-life cons perpetrated by brothers Fred and Charley Gondorff and documented by David Maurer in his 1940 book "The Big Con: The Story of the Confidence Man".
