Major League Baseball (MLB) honors its best relief pitchers with a Reliever of the Month Award for one pitcher in the American League (AL) and one in the National League (NL) during each month of the regular season. These awards have been issued since 2017. From 2005 to 2013, MLB honored a single relief pitcher across both leagues with the Delivery Man of the Month Award during each month of the regular season.
