White Abarrio, thoroughbred racing’s warrior who has excelled and faltered in many of the sport’s richest events, is ready to go again. This time, the 7-year-old nearly white gelding is primed for the $1 million Whitney Stakes (G1) at Saratoga on Saturday in what could be the Race of the Year. Plus, the winner earns a fees-paid berth to the Breeders’ Cup Classic (G1) on Oct. 31 at Keeneland.
