Agree
I wouldn't look for a SP. Take advantage of the break. Run a 6 man rotation when Ryu is back. You have built depth if a starter goes down. And you only need 4 SPs for the post season.
We need a bat at DH, 2B and/or OF to maybe platoon with Belt and Varsho and/or replace Kirk as a DH. A rental would be fine.
Bullpen might be OK if Pop and Green are healthy but you add a solid piece if you can anyway.
Don't want to deplete the farm much to help this all happen and I don't think you even need to.
