Race 7 (3:06PM ET) // Claiming // 6 Furlongs (Dirt) 

1-Itsmyluckygirl (25% W // 40% P // 52% S)
6-Ima Daredevil (15% W // 32% P // 45% S)
5-Poseidon’s Princess (11% W // 29% P // 44% S)
12-Lemoncita (10% W // 18% P // 25% S)

Jeremy’s Take: This is a balanced race to start, so get some coverage. The algorithm and I agree on 1-6 at a minimum, but I’ll take 1-2-3-6-11.

Race 8 (3:40PM ET) // $75,000 Proud Man S. // 1 Mile (Turf) 

7-Fulmini (21% W // 28% P // 42% S)
1-Hot Blooded (19% W // 47% P // 57% S)
3-Hail Rich Legacy (14% W // 30% P // 42% S)
6-Savatiano (14% W // 30% P // 53% S)

Jeremy’s Take: Man and machine agree on 1-7 at the top of this ticket. But the percentages show it’s balanced with only a 2-point spread on the top pair and only 7 points among the top four – the closest margins in the Rainbow 6. I’ll spread a bit in this race with a quartet, 1-7-8-9.

Race 9 (4:14PM ET) // $200,000 Susan's Girl S. // 7 Furlongs (Dirt) 

5-Princess Secret (33% W // 55% P // 68% S)
6-Oh Deborah (22% W // 49% P // 73% S)
1-Freak (17% W // 35% P // 52% S)
3-Alluramore (11% W // 23% P // 31% S)

Jeremy’s Take: The 1/ST INDEX gives a surprising snub to 4-Go Jo Jo Go, 21-1 upset winner of the Desert Vixen. Perhaps the data agrees that lightning doesn’t strike twice? I’ll go 3-deep with 5-4-3.

Race 10 (4:48PM ET) // $75,000 Sharp Susan S. // 1 Mile (Turf) 

5-Spanish Loveaffair (30% W // 44% P // 55% S)
4-Director’s Cut (14% W // 23% P // 40% S)
2-Can’t Buy Love (12% W // 25% P // 36% S)
1-Special Inclusion (10% W // 25% P // 29% S)
3-Beach Chick (10% W // 16% P // 34% S)

Jeremy’s Take: The 16-point spread from first to second is the widest in the Rainbow 6, and I’m in total agreement with the algorithm here. This is all about 5-Spanish Loveaffair. Single 5.

Race 11 (5:21PM ET) // $200,000 Affirmed S. // 7 Furlongs (Dirt) 

6-Breeze On Bye (32% W // 51% P // 58% S)
1-Gatsby (17% W // 33% P // 45% S)
4-Big Daddy Dave (12% W // 24% P // 37% S)
5-Seazan (12% W // 27% P // 42% S)

Jeremy’s Take: While many may be singling the favorite morning line favorite 6-Breeze On By, and the 15-point spread in this race is a solid endorsement of that, I’ll be using a trio of runners. Give 4-Big Daddy Dave an upset shot as the distance here at 7 furlongs could be the tripping point for the favorite. Use 4-6-1.

Race 12 (5:54PM ET) // Claiming // 1 1/16 Miles (Turf) 

9-Duchossois (23% W // 43% P // 47% S)
7-Policy Option (17% W // 24% P // 37% S)
10-Atakan (13% W // 26% P // 37% S)
6-Time for Trouble (12% W // 24% P // 32% S)

Jeremy’s Take: With a 12-1 choice on the artificial intelligence top pick 9-Duchossois, you can’t argue with a price to close the card. My handicapping focus was on the top pair in the morning line, 6-Time for Trouble and 7-Policy Plan, a less creative decision. My plays amount to a $72 ticket if there are no scratches.
