quite a few of the once in a blue moon patrons at these huge events don't understand place and show and others just bet one horse to win, one to place and one to show
it can cause favorites to pay more than they should in the place and show pool - it's not a boxcar thing but can create an edge
American Pharoah went off at 4/5 in the Preakness and paid almost as much to place - $3.40 - in an 8 horse field. - $2.80 to show
Justify went off at 2/5 in the Preakness and paid the same to place as to win - and he paid $2.60 to show also in an 8 horse field - show got you 75% of the profit of the win bet
they came with shots and that helped but still
it happens fairly often on these huge racing days
