Morning Line

An approximation of expected odds in a race, quoted before actual odds are determined.

State-Bred

A horse bred in a particular state and thus eligible to race in restricted state-bred races. These can be anything from maiden races to stakes events.

Trifecta

A wager picking the first, second and third horses in the exact order. A trifecta box means paying more to ensure the horses can finish in any order in the top three spots.
