One thing to know: Alwaysmining is one of the fascinating wild cards racing at Pimlico on Saturday. He's run 10 races in his career, and is undefeated in his past six, making him the winningest horse in the field by a mile. The Preakness presents a tougher challenge than his previous races, but if you like backing a horse that's proven himself a winner, Alwaysmining offers some excellent odds.
