Dona Camile (6), at 7-2, won Thursday's fourth race at Gulfstream Park to start the Rainbow 6.
Bettors added $88,709 to the Rainbow 6 pool. The carryover coming in was $128,559.
Gulfstream has guaranteed the the pool will be at least $250,000 if there is just one ticket with all six winning horses. In that case, Gulfstream would need to put in about $33,000 to cover a payout.
We will be back at the race day's end, for a wrap-up.
