Today's AU - Doomben Horse Racing Picks

Scratch

A horse is a scratch when injury or other necessity causes it to be withdrawn from the race.

Bolt

A sudden veering to the inside or outside rail, often caused by the horse spooking or shying from something.

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.
