Gulfstream Park will have a special Labor Day program on Monday, with ten races and first post at 12:00 p.m.
There will be two stakes races, both with $75,000 purses and both at 1 1/16 miles on turf.
The Monroe is for fillies and mares 3-YO and up and the Mr. Steele is for males 3-YO and up.
The Rainbow 6 has a carryover of $97,617. The 20 cent per combination-only bet will be on races five to ten, with the sequence scheduled to start at 2:17 p.m.
Gulfstream has guaranteed that the Rainbow 6 pool will be at least $300,000 if there is just one ticket with all six winning horses. Such a ticket would take down the jackpot of the full carryover plus 80 percent of the day's new Rainbow 6 bet.
Labor Day Stakes
The Monroe will be the fourth race and will feature a rematch of the top three finishers in the 1 1/16 mile Dayatthespa Stakes at Gulfstream on Aug. 9.
Sensible Myth beat Kelsey's Cross by a neck in that race and Great Sister Diane came in 1 1/2 lengths back in third.
Hall of Famer Edgar Prado has the return mount on Sensible Myth for trainer Leo Gabriel Jr. Rajiv Maragh will ride Kelsey's Cross for Patrick Biancone and Hector Berrios will ride Great Sister Diane for Rohan Crichton.
The Mr. Steele will be the eighth race. Sailing Solo, trained by Louie Roussel III, is the 5-2 morning line favorite on the strength of his three-length victory over Harbour Master in the Mecke Stakes on July 25 at Gulfstream.
Sailing Solo led at every call in the Mecke, at one mile on turf. Prado has the return ride on Sailing Solo.
Harbour Master is not entered in the Mr. Steele. Galleon Mast who finished third in the Mecke, is in the field. Both of those horses are trained by David Fawkes. Emisael Jaramillo has the return call on Galleon Mast.
Morning Stride also is in the Mr. Steele. On Aug. 16, he won the 1 3/16 mile Richard Henry Lee Stakes at Gulfstream for trainer Monica McGooey. Berrios has the return mount.
Sailing Solo, a 5-year-old son of Smart Strike, is 2-for-2 at Gulfstream. On June 26 at the Hallandale Beach track he came off a four-month layoff to win a 1 1/16 mile turf optional claimer. He led gate-to-wire, ridden by Prado.
On Sunday, each ticket with all six Rainbow 6 winners paid $893.68 on a cent bet.
HorseRacingFLA's review of Equibase charts shows there were 130 such tickets.
Program numbers of the winning horses were 10-6-3-7-6-8.
All six winners, including three favorites, were at odds of 4-1 or lower.
Bettors added $208,586 to the Rainbow 6.
Per its rules on days with multiple winning tickets, Gulfstream took out 20 percent of the day's bet. It then divided 56 percent among winning tickets and added 24 percent to the carryover.
