Minus Pool

A pari-mutuel pool – typically a show pool - where one horse is so heavily bet that after deductions there is not enough money left to cover the prescribed minimum on each bet.

Blinkers

A hood worn on a horse’s head to limit side vision, which can improve concentration. Blinkers are added or removed to relax a horse or give it more focus.

Sloppy

A wet racetrack condition, typically with a firm base and water settling on top.
