Today's Cal Expo Horse Racing Picks

Underlay

A horse that is going off at lower odds than it deserves based on performance.

Bolt

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

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.
