Gulfstream Park on Sunday will have a mandatory payout on its Rainbow 6--no matter the number of tickets with all six winning horses.
The pool will start with a carryover of $873,676,
Based on Gulfstream's recent betting history, the track's management anticipates that the large carryover will lure in about $5 million in new Rainbow 6 bets.
Gulfstream has an eleven-race card with first post of 12:40 p.m.
The Rainbow 6 is on races six to eleven with the sequence scheduled to start at 3:10 p.m.
We will have an expanded version of this story later this morning.
