Leonard is out of options, right? So if he comes to Milwaukee he needs to stay here or be exposed. With Lockridge out & Yelich being a ? right now, Black also being an option...........I think Leonard was one of those deals where his best shot was making the team out of ST, and now that he didn't it's a little dicey.
I also get the feeling they'd like to leave Chourio in LF, which could further complicate Leonard being on the roster. That also gives Mitchell a longer leash. Of all the whipping boys on the roster---Rengifo, Ortiz, Mitchell, Frelick, Hamilton---Mitchell is arguably the most vulnerable, but it's probably going to take even more extended struggles from him for a change to be made.
