Friday's ten-race card is underway at Gulfstream Park, with conditions listed as Fast and Firm.
The carryover on the Rainbow 6 is $51,302.
The 20 cents per combination-only bet is on races five through ten, with the sequence scheduled to start at 2:17 p.m.
Gulfstream has guaranteed that today's Rainbow 6 pool will be at least $150,00 if there is just one ticket with all six winners.

*75,000 Miss Gracie -- 7 1/2 furlongs on turf, 3-YO fillies
