I can't believe we used 38 pitchers. That's an insane number of arms to be plied at the major league level. The 1970 Baltimore Orioles won the world series and used a total of 12 pitchers all year. The 1974 Oakland A's won the world series using 11 pitchers all year. Maybe part of the decline of the popularity of baseball is the use of so many players and loss of personal identity in a baseball game.
Also, according to FanGraphs relief pitchers accounted for only about 9-10% of the value (in wins above replacement) that all position players and pitchers created last year. And yet, they occupy about 25 percent of roster slots. Relief pitchers are eating baseball alive, lol.
