Players that opted in to TwinSpires.com‘s January Road to the Derby Bonus Cash offer earlier this week and backed the winning favorite Mind Control in Tuesday’s $150,000 Jerome at Aqueduct will receive a $10 bonus after placing $20 Win wagers on the remaining three Kentucky Derby (G1) preps this month. As Mind Control paid $5, a $20 Win bet returned $50. Add $10 to that, and backers essentially got a 2-1 price rather than 3-2. My selection, Our Braintrust, was second best in the Jerome, so I’ll be receiving 20 percent of my wager back later this month. Saturday’s $100,000 Sham (G3) at Santa Anita is the next Derby prep on the schedule and the next mandatory play in the January Road to the Derby Bonus Cash offer. A field of seven was entered, with the Bob Baffert-trained #5 COLISEUM the even-money favorite on the morning line. Off a 6 3/4-length debut win at Del Mar in November, the son of Tapit appears to have the most raw talent of anyone in the Sham field. That’s not to say he’s a cinch. #6 GUNMETAL GRAY (5-2) was second best to likely champion Game Winner in the American Pharoah (G1) prior to running a distant fifth to the same rival in the Breeders’ Cup Juvenile (G1). The Baffert-trained #7 MUCH BETTER (6-1) has useful form outside of a poor try on soggy ground in the Breeders’ Cup Juvenile Turf (G1), while #2 GRAY MAGICIAN (4-1) impressively landed a Del Mar maiden in his two-turn debut. In the end, though, it’s hard to side against what many consider one of the leading classic prospects from a five-time Derby- and two-time Triple Crown-winning trainer (he closed at 10-1 in the first Kentucky Derby Future Wager pool). I’ll be placing my $20 Win bet on Coliseum in the hopes of getting a mild bonus on the final odds. If he starts at 1-1 and wins, the effective win payoff with the bonus is 3-2. If he dips to 4-5, the effective win odds will be 13-10. If he floats up to 6-5, the effective wins odds with the bonus would be 17-10.
