Today's Cal Expo Horse Racing Picks

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.

Bolt

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

Stewards

The officials watching every race at a meet to enforce the rules.
