I think injuries are to be expected (Wahl, Topa, File was probably projected up at some point and now looks like 2022). The bullpen struggles are due to the greater than expected regression with the best RP last year struggling to keep a roster spot and the second best RP already having lost his spot. I think Stearns realized it after the fact with the return for Arcia. Bickford also had a great spring and could be worth a look. Got to believe the second half bullpen plan has one or two of Ashby, Small, or Bettinger making it up.
