What is middle relief pitcher?

A middle relief pitcher is a baseball player who is primarily used to pitch in the middle innings of a game, typically from the 5th to the 7th inning. Middle relief pitchers are not considered to be the top pitchers on a team but are instead seen as more versatile pitchers who can be used in a variety of situations. They may be used to bridge the gap between the starting pitcher and the closer or to protect a lead in the middle of a game. Middle relief pitchers must be able to get batters out consistently and may need to have a variety of pitches in their repertoire to do so. They may also need to be able to pitch multiple innings in a single game as they often begin their outings in the middle innings and finish them in the later innings.
