The best move might be to keep Hall pitching in Nashville this season as long as possible. I’m not familiar with the 60-day IL rules as how long he can continue his rehab stint. Even though he has pitched adequately during his rehab in the MiLB this year with all the other options available he is still down on the list of MLB ready pitchers. At this point in the season I would rule out even looking at him as a SP with the stats he accumulated with the Brewers earlier this year (16.1 IP, 7.71 ERA, 2.265 WHIP, 27 H, 10 BB, 4 HR) unless he would fill the 1 inning starter role. Pitchers that are ahead of him if healthy and ready as you noted would be; Megill, Hudson and Wilson. With the experience of Peguero, Milner and even Ross in a pressure filled pennant race they would be preferable to Hall’s 1 year with Baltimore in 2023. Misi and Yoho should be completely off the table unless utter disaster happens. There is no reason to do anything with Ashby any longer this year.
