First horse ever to win the derby outside the 17th post. …ever.
Plus any horse in a muddy race that came from behind is carrying extra weight of at least 2-3 pounds
Not true. Several horses have won from the 20+ spot, even recently. Rich Strike, Country Home, and Big Brown.
There have been 20-ish horses whenever I have watched.
In how many years were there fewer than 17 horses?
