To go along with each Derby Dozen post, I'll put out a current dark horse candidate.
Awesome Partriot gets the first nod along the road. This son of Awesome Again should have no problem with races up to nine furlongs - really no one knows if a horse will stay the 10 furlongs until they try on Derby Day - which most of the major Derby preps are run at. He's stakes placed, third in Hollywood Prevue at 7 furlongs, and an allowance winner in his last start at two-years-old racing one mile on Santa Anita's natural dirt.
Oh did I mention that he's trained by Bob Baffert, who at last count had 50 Derby hopefuls. With a return to dirt Baffert's winning at a crazy clip out west (44% win and 74% in the money to date) and that's only going to continue with his three-year-old charges.
Listen, it's early, but you could do worse than a two-turn winner on dirt by a Breeder's Cup champion, trained by Baffert, currently sitting between 100-1 to 250-1 at Vegas sports books.
