Horseplayers across the country will turn their attention to Gulfstream Park on Saturday, when the Rainbow Pick 6 jackpot is set for mandatory dispersal.

Heading into Thursday, the carryover pool stands at $918,857. Assuming no unique winning tickets are sold on Thursday or Friday, mandatory dispersal day could see the total pool climb past $5 million.

But why wait until Saturday to take aim at a big payday? Thursday’s Rainbow 6 carries a guaranteed pool of $1.4 million, and if you’re lucky enough to assemble the only winning ticket, a million-dollar prize will be yours.

Of course, you’ll never construct a unique ticket by betting a bunch of favorites. To cash the jackpot, you’ll need double-digit longshot winners, and a bunch of them.

Let’s take a quick look at Thursday’s Rainbow 6 sequence, focusing our attention on turf races over dirt races since grass events tend to be more competitive than their main-track counterparts. We’ll aim to identify a couple of longshots with the potential to outrun expectations and propel us toward a rewarding Rainbow 6 payoff.

Race 7: $35,000 Claiming (1 mile on turf, 3:40 p.m. ET)

With 11 entries, including one main track-only runner, Race 7 drew the largest field of any race in the Rainbow 6 sequence. In hunting for longshots, one could do worse than support #2 Reagan’s Rose (20-1).

Although she’s been competing against stakes company on dirt as of late, Reagan’s Rose wasn’t disgraced in her most recent run on turf, finishing third in a 1-mile allowance optional claiming race at Gulfstream Park West. The 82 Brisnet Speed rating Reagan’s Rose posted is actually right on par for Thursday’s class level and distance.

Race 10: $20,000 Maiden Claiming (7 1/2 furlongs on turf, 5:13 p.m. ET)

The finale is a competitive maiden claiming event with nine starters, #2 Winnipeg Wonder (3-1) is the favorite while dropping down from maiden special weight company, but she isn’t a standout from a Brisnet Speed rating perspective.

Indeed, #7 Rosey’s Invasion (10-1) ran almost as fast while competing for $40,000 claiming tags against New York-breds last year. The daughter of Normandy Invasion has tactical speed and can fire a good shot for trainer Domenick Schettino, who strikes at a 30% rate when dropping horses down multiple claiming levels.

Good luck!
