<P> In Major League Baseball (MLB), the 300 save club is the group of pitchers who have recorded 300 or more regular - season saves in their careers . Most commonly a relief pitcher ("reliever" or "closer") earns a save by being the final pitcher of a game in which his team is winning by three or fewer runs and pitching at least one inning without losing the lead . The final pitcher of a game can also earn a save by getting at least one batter out to end the game with the winning run on base, at bat, or on deck, or by pitching at least three innings without relinquishing the lead, regardless of score . The statistic was created by Jerome Holtzman in 1959 to "measure the effectiveness of relief pitchers" and was adopted as an official statistic by MLB in 1969 . The save has been retroactively measured for past pitchers where applicable . Hoyt Wilhelm retired in 1972 and recorded just 31 saves from 1969 onwards, for example, but holds 227 total career saves . </P> <P> Mariano Rivera holds the MLB save record with 652 . Only Rivera and Trevor Hoffman have exceeded 500 or 600 saves, and Hoffman was the first to achieve either . Rivera, Hoffman, Lee Smith, Francisco Rodríguez, John Franco, and Billy Wagner are the only pitchers to have recorded 400 or more saves . Rollie Fingers was the first player to record 300 saves, reaching the mark on April 21, 1982 . Craig Kimbrel is the most recent, achieving his 300th on May 5, 2018 . In total, 29 players have recorded 300 or more saves in their career . Only six relievers--Dennis Eckersley, Fingers, Goose Gossage, Hoffman, Bruce Sutter, and Wilhelm--have been inducted into the Baseball Hall of Fame; all but Wilhelm are also members of the 300 saves club . Kimbrel, Fernando Rodney, and Rodríguez are the only members of the 300 save club who are still active players . Of them, Rodríguez is the active leader in saves with 437 . </P> <Table> <Tr> <Td> Player </Td> <Td> Name of the player </Td> </Tr> <Tr> <Td> SV </Td> <Td> Total career saves </Td> </Tr> <Tr> <Td> Date </Td> <Td> Date of the pitcher's 300th save </Td> </Tr> <Tr> <Td> Team </Td> <Td> The pitcher's team for his 300th save </Td> </Tr> <Tr> <Th> </Th> <Td> Elected to the Baseball Hall of Fame </Td> </Tr> <Tr> <Th> </Th> <Td> Player is active </Td> </Tr> </Table>
