As a collective unit, the Cleveland Indians bullpen logged 507 1/3 innings in 2019. Only the Washington Nationals pitched fewer relief innings. Like with the Nationals, a couple of factors contributed to this for the Indians.
Chief among them is that the Tribe’s starting rotation combined to pitch 930 1/3 innings, third-most in MLB. When a team’s starters consistently go deep into games, it naturally reduces the need to rely heavily on the bullpen.
Going hand-in-hand with this is that the Indians still take a traditional approach to their pitching staff.
