More to Come for Protonico, Sire of Kentucky Derby Winner Medina Spirit

For all the round-the-clock pedigree scrutiny and conformation analysis that goes into finding a stallion that will produce a winner on the first Saturday in May, it took a horse standing for $5,000 and lacking that coveted Grade I win on their race record to get the job done.
Of the 26 fifth-year stallions standing in Kentucky today, Protonico was one of five to breed less than 20 mares last year. And yet, here he is now sitting atop the Leading Second-Crop Sires list after his son Medina Spirit charged home to win the 2021 GI Kentucky Derby at 12-1 odds.
