Saturday is closing day of the Gulfstream Park West, which means a mandatory payout in the Rainbow 6. The carryover heading into closing weekend was more than $300,000. The sequence on Races 5-10 will attract a multi-million dollar pool and create potentially boxcar payoffs for those lucky enough to take down the 20-cent base wager.

Selections provided by the 1/ST BET app measure each contender against the 10 leading factors for each race. The 1/ST BET app looks at 52 handicapping factors and more than 200,000 past races to determine its AI selections. You can use the automated handicapping factors, or create your own factor filters to incorporate angles you prefer.

Race 5 (2:31PM ET) // claiming // 1-1/16 miles (turf)

11 – Keep Quiet (23% W)
7 – Twenty Four Seven (15% W)
1 – Nacho Papa (13% W)
4 – Ice Tea (10% W)

Notable: Favorites have won 46% in turf claiming races at the 2020 GPW meet. Trainer Saffie Joseph Jr. has the top 2 choices, according to 1/ST BET. The 23% win rate for Keep Quiet matches the highest in the Rainbow 6, and the 8-point spread among the top pair is the co-largest in the sequence.

Race 6 (3:00PM ET) // maiden claiming // 7 furlongs

3 – La Gata Negra (23% W)
10 – Maricopa (18% W)
7 – Queen Letizia (16% W)
4 – Captured Light (9% W)

Notable: Favorites win an expected 35% in maiden claiming dirt races at the GPW meet. Madame Moon has been beaten favorite in her last 2 at short odds, and the 1/ST BET algorithm dismisses her chances today at only 7%, perhaps providing overlays elsewhere. The 23% rating for La Gata Negra matches the highest in the Rainbow 6 today.

Race 7 (3:29PM ET) // claiming // 1-1/8 miles (turf)

4 – Robin Team Show (15% W)
1 – Yadi (15% W)
15 – Cark (9% W)
9 – Bad Boy E.J. (9% W)

Notable: Favorites have won 46% in turf claiming races at the 2020 GPW meet. But even identifying the favorite here is not an open-and-shut case. The 1/ST BET app tabs this the most difficult race to decipher. The 16 entrants, including also-eligibles, have 9 totals wins among them in 2020. This will be the logical race to spread your options.

Race 8 (3:58PM ET) // claiming // 6 furlongs

6 – Rock With Robin (23% W)
4 – Include the Beast (18% W)
3 – Hokkaido (14% W)
1 – Mak Hero (11% W)

Notable: Favorites are an expected 37% in maiden claiming dirt races at the GPW meet. The top 3 choices here by 1/ST BET all hail from barns that are going very well at the moment. Consider the trio strong, and if you can pare down from there, this is a place to minimize the ticket cost some.

Race 9 (4:27PM ET) // claiming // 1 mile (turf)

11 – Projected (21% W)
3 – Honey Dont (15% W)
8 – Create Again (15% W)
5 – My Point Exactly (12% W)

Notable: Favorites have won 46% in turf claiming races at the 2020 GPW meet. Top 1/ST BET choice Projected as well as My Point Exactly both go for hot trainer Carlos David. Surprising to see Monmouth shipper Macagone lightly regarded by the algorithm at 10%; seems like a player on paper and should be included to this eye.

Race 10 (4:56PM ET) // maiden claiming // 7-1/2 furlongs (turf)

1 – On Duty (22% W)
3 – Call Bros (14% W)
12 – Oxburger (7% W)
13 – Big Perm (7% W)

Notable: Favorites slightly underperform at 33% in maiden claiming turf races at the GPW meet. The 8-point spread among the top pair is the co-largest in the sequence as On Duty drops in class and comes south for the first time. Several of the top contenders are on the also-eligible list, so the separation from On Duty and Call Bros may be even greater to the remainder when the field finalizes. Consider moving up Karamojo to the consideration.
