I am not playing but this is my bet.

Race 3 - Glassy and Singalong
Race 4 - Silver and Black (biggest drop in racing)
Race 5 - Princess McLeand and Smart Kitten and Kelly Carson
Race 6 - Calamity June (boy is she fast and dropping)
Race 7 - Rosy Lea and Indy Miss and Malinche and I can see
Race 8 - Open My Eyes and Miami Bay and Goose's Choice and Dyno Dog

1*2*3*1*4*4 (2) = $192.00
