Major League Baseball (MLB) annually honored its best relief pitcher with the Major League Baseball Delivery Man of the Year Award from 2005 through 2013.
It was initially part of a sponsorship agreement between MLB and package delivery company DHL Express; DHL's sponsorship ran from 2005 to 2010.
From its inception in 2005 through 2008, the award was given to a single reliever who was selected online by fans from a group of 10 finalists chosen by an MLB panel.
[3][4] The panel took sole responsibility to select the annual winner starting in 2009.
[3][5] Mariano Rivera was the only pitcher to win the annual award more than once, receiving it in 2005, 2006, and 2009.
