Wagner’s Hall of Fame case seems to pick up steam with every year he appears on the ballot. Among his peers, the only reliever from Wagner’s era who was definitively better than him was the greatest closer of all-time — Mariano Rivera. Wagner’s 2.31 career ERA and 1.00 WHIP are among the best marks of any pitcher in league history. He was one of the best relievers in all of baseball even by the time he called it quits in 2010 (Wagner sported a career-low 1.43 ERA in his final season). Wagner’s one blemish, unlike Rivera, was his lack of postseason success. However, the 5-foot-10 lefty did more than enough in 853 regular season appearances to warrant 75-percent of the Hall of Fame vote.
