Match Race (MAT)
A match race is a race that involves just two horses. It can be run under a number of conditions, but generally is run in allowance or handicap conditions.

The race does not qualify as a MATCH RACE if more than two horses originally entered the race and some were scratched, making it a two-horse field.
