Major League Baseball (MLB) honored its best relief pitchers with a Delivery Man of the Month Award for one pitcher during each month of the regular season from 2005 through 2013. The awards were initially part of a sponsorship agreement between MLB and package delivery company DHL Express; DHL's sponsorship ran from 2005 to 2010. There was also a Delivery Man of the Year Award; all of the Delivery Man awards were discontinued after 2013. A new Reliever of the Month Award was first awarded in 2017.
