 The requirements for a thoroughbred racehorse to run in the Kentucky Derby are straightforward. They must be three years old and they must have earned enough points in prepped races to qualify for one of the 20 spots at the starting gate. Where a horse is born or bred doesn't matter or doesn't. Many states in the U.S. not known for horse racing have been home to derby winners. For example, Tennessee was represented with three winners way back at the turn of the 19th century. However, no corner of the earth has produced more derby winners than the Commonwealth of Kentucky itself, accounting for 114 winners. The last time a horse won the Kentucky Derby not bred in Kentucky was California Chrome in 2014. So whether you choose a horse from Japan or Kentucky bred, all that matters is that you choose the winner. Bet the Kentucky Derby Saturday May 6 with Fandall Sportsbook.
