The Kentucky Derby preps are to the Kentucky Derby as the National Hockey League regular season is to the NHL playoffs. It is a months-long grind that began last fall, it ends on Saturday, and it involves quite a bit of scoreboard watching to see who’s in and who’s out.
A maximum of 20 horses can start in the Derby. If it overfills, then the points earned in the prep races will determine who gets to run. For those on or near the bubble right now, it’s nervous time.
