Mitch Keller from the Pirates is someone we should target imo. Former top 20 prospect with a few of years of control left who has put up middling numbers despite his high-level stuff.
Sounds like a familiar story (Cole, Musgrove, Taillon)...
Would be a nice back of the rotation addition at the very least with the potential for more if our pitcher development system is able to work its magic once again. Also, would add another option for next season, when we'll presumably be without Burnes.
