Today's GB - Doncaster Horse Racing Picks

Yielding

A rain-soaked turf condition often producing a slick or heavy course and slower finish times.

Underlay

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

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.
