Conditions are listed as Fast and Firm for Friday's nine-race card at Gulfstream Park in Hallandale Beach, Fla.
First post is at 12:00 p.m.
The Weather Channel forecast is for a 20 percent chance of rain during racing hours.
The first race has a Super Hi-5 carryover of $2,675.
The Rainbow 6 has a carryover of $149,870. The 20 cents per combination-only bet will be on races four to nine, with the sequence scheduled to start at 1:30 p.m.
Gulfstream has guaranteed that the Rainbow 6 pool will be at least $250,000 if there is just one ticket with all six winners. That is the requirement for taking down the Rainbow 6 jackpot of the full carryover plus 80 percent of the day's new Rainbow 6 bet (20 percent takeout).
If there are multiple Rainbow 6 winning tickets, Gulfstream will take out 20 percent of the day's Rainbow 6 bets. It will then divide 56 percent among tickets with the most winners (usually six) and add 24 percent to the carryover.
