Call
A race caller is a public-address announcer or sportscaster who describes the progress of a race, either for on-track or radio and TV fans. They are most prominent in horse racing, auto racing and track-and-field events.
Among the jobs of a race caller is to identify the positions of various entrants during the race, and point out any sudden moves made by them. In horse racing, many callers also point out the posted fractions—the times at which the lead horse reached the quarter-mile, half-mile and similar points of a race.
A race-caller who specifically describes the event over a racetrack's public-address system is the track announcer.In horse racing, track announcers handle up to nine or ten races per day; more on special stakes-race days.
Most horse-race callers memorize the horses' and jockeys' silks and the horses' colors before the race, to be able to quickly identify each entrant. During a racing day, track announcers also inform patrons of scratches, and jockey/driver and equipment changes.
