On this day in 1992 four men were officially inducted into the baseball Hall of Fame: longtime umpire Bill McGowan and pitchers Hal Newhouser, Tom Seaver and Rollie Fingers.
Fingers may have been the most historically significant of the inductions, because at the time he was one of just two pitchers enshrined who had been primarily used as relievers (joining Hoyt Wilhelm). Fingers came out of the bullpen in 907 of his 944 career appearances, notching 341 saves. 97 of those saves, two All Star appearances and the 1981 AL Cy Young and MVP Awards came as a Brewer.
Here's the text from Fingers' Hall of Fame plaque:
