High Quality Content by WIKIPEDIA articles! In baseball, a closing pitcher, more frequently referred to as a closer (abbreviated CL), is a relief pitcher who specializes in getting the final outs in a close game when their team is leading. The role is often assigned to a team`s best reliever. Before the 1990s, pitchers in similar roles were referred to as a fireman, short reliever, and stopper. A small number of closers have won the Cy Young Award. Dennis Eckersley, Rollie Fingers, Goose Gossage, Bruce Sutter and Hoyt Wilhelm are closers who have been elected to the Baseball Hall of Fame.
