The All-Star rosters have 12 spots for pitchers, so typically between five and seven go to relievers. Accounting for replacements and injuries and opt-outs, let’s just call it eight relievers. The proposition of this article is simple: Gabe Speier has been one of the eight best relievers in the American League.
Of the AL relievers who’ve thrown at least 25 innings, Gabe Speier has one of the eight highest strikeout rates. And Gabe Speier has one of the eight lowest walk rates. That combination is hardly an accident: he’s earning those results with one of the eight highest CSW% (the percentage of his pitches that end with a called strike or a whiff).
