I have no dog in last nights horizontals, but I have previously complained about Santa Anita late Pick 4 payouts. I have numerous times cashed the late Pick 4 there and have had it pay less than what the parlay would have paid. The explanation normally given to me is that a long horse in my sequence was much shorter in the ML and was probably played more in the horizontals due to lower ML than would have been expected based on actual off odds.
