Since Workman won't be going away and Thornburg is sucking at AAA (0-2, 15.43 ERA, 2.79WHIP in a small sample of 4.2 innings), that leaves Wright or Johnson . No clue as to whether Wright can pitch effectively, and k'ballers are always a crap shoot . No one would miss him being gone. Brian Johnson is his own dilemma. Was the 5 innings vs Toronto, the real deal or just another teaser ? SW and BJ could both go if it solved a problem. Same for the bad back of Hector V. None of those 3 should be in any serious plan for 2020.
Wrights record at PawSox is better than Thornburg. 1-0, 1.86ERA and 0.93 WHIP. Throwing his junk at AAA'ers is working for him. I imagine he will get both a chance in a couple days as well as some showcasing prior to the July deadline.
