The fourth race is coming up on a ten-race Sunday card at a rainy Gulfstream Park in Hallandale Beach, Fla.
Heavier rain and wind are expected later in the afternoon and tonight, as southeast Florida feels the impact of Tropical Storm Isaias.
But it appears that Gulfstream will be able to run its full Sunday card. All of the remaining races are scheduled for the dirt track that is listed as Sloppy and is sealed.
The carryover on the Rainbow 6 is $889,911.
The 20-cents per combination-only bet is on races five through ten with the sequence scheduled to begin at 2:02 p.m.
The featured ninth race is the $60,000 Opening Lead Stakes at six furlongs on dirt for 3-years-old and up.
