What is the person making remarks about a sports competition called?

Answer 1

It can vary from sport to sport or from television versus radio. Typically, all are collectively known as sports broadcasters, commentators or sportcasters.

It's normal to have a two-person team. The lead commentator is typically referred to as the play-by-play announcer and will comment as each play happens.

The secondary role is called the analyst. He or she might chime in interesting stats, trends or figures when there is a break in the action.
