Northfield Park - Race 10

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.

Superfecta

A wager involving choosing the first, second, third, and fourth horses in one race in the exact order. A superfecta box involves paying more to ensure they can finish in any order in the top four spots.

Main Track Only

A horse entered for main track only (MTO) is one hoping the weather forecast or track conditions will move the race off the turf course and onto the main track. They are scratched the morning of the race if the conditions stay dry.
