The Chicago White Sox have done much of the heavy lifting for their offseason already, but the team could still use some bullpen help which is an area of need they haven’t addressed yet.
However, if the team doesn’t end up acquiring a couple of bullpen arms, their starting pitching rotation additions could be all for nothing if the bullpen blows their leads consistently.
In 2019, the White Sox actually did rank in the middle of the pack with a 4.31 bullpen ERA which was good for 14th in all of baseball (ESPN).
Outside of Alex Colome, though, there are no guarantees going into the 2020 season.
Left-hander Aaron Bummer had a very solid season for the team in 2019 with a 2.13 ERA over 67 2/3 innings, but had a 4.36 ERA over the first two seasons of his career (53 2/3 innings).
Evan Marshall also enjoyed a very good season as he had a 2.49 ERA. But with this being the fourth organization he’s played with at the major league level and the fact that he had a 5.15 ERA prior to that, it is at least questionable whether or not he can repeat that success.
