context_page_description: Major League Baseball annually honors its best relief pitchers in the American League and National League with the Mariano Rivera AL Reliever of the Year Award and Trevor Hoffman NL Reliever of the Year Award, respectively. The awards are named after Mariano Rivera and Trevor Hoffman, who played their entire careers in the respective leagues. First issued in 2014, the awards replaced the Major League Baseball Delivery Man of the Year Award, which had been presented since 2005. Also in 2014, the Major League Baseball Delivery Man of the Month Award was discontinued. The Reliever of the Year Award winners had all been closers until 2018, when Josh Hader of the Milwaukee Brewers won as a setup man, but he won the NL title in 2019 as a closer.
  The Reliever of the Year Awards are based on the votes of a panel of retired relievers. Each voter selects three pitchers for each league based solely on their performance in the regular season; a 5-3-1 weighted point system is used to determine the winner.
