Arroyo has done fine, when healthy. In the rotation/platoon I am talking about (not advocating for) would not really "count on him," since we have several other options to go with.
One issue is we can't have 6 guys on the bench rotating at DH. It will have to be 3, with one being a back up OF'er (Refsnyder?) and one bing a back up infielder (Arroyo, when healthy or maybe EValdez) plus Dalbec or Hosmer, and since Hosmer is a lefty bat, it would likely be him. (Dalbec, Valdez & Ref have options.)
I'd love to improve on our .763 DH OPS, this year, but if we can greatly improve RF, stay even at SS and see Kike return to near 2021 levels, we may be able to afford just coming close to .763 in 2022.
Can this combo give us .763 or better?
Hosmer v R
Ref/Arroyo v L
I think it's a close call. I'd love to improve on it, but we may not have enough resources to fill every wish on the wish list.
