Sure, Mariano Rivera and Trevor Hoffman are two names that everyone throws around from the late 1990’s through the 2000’s in terms of top closers. Rivera and his cut fastball are considered legendary. Hoffman and the use of his change-up is incredible to look back upon. Both pitchers will be enshrined in Cooperstown sooner or later.
However, other closers had stretches of dominance that rivaled Rivera and Hoffman. Billy Wagner can be counted as one of those other closers and probably should be in the conversation for induction into Cooperstown.
