Los Alamitos Thoroughbred

Scratch

A horse is a scratch when injury or other necessity causes it to be withdrawn from the race.

Fractions

The times recorded during the race; with timing starting just past the gate or when the gates open, then parroted for the quarter, half, three-quarters etc. Used as an indication of ability and speed.

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.
