Keep Robert, Vaughn, Burger, Colas, Sosa, Zavala, Cease, Kopech, Lopez, Crochet, Banks, Middleton
Trade anybody and everybody else you can get a decent return on.
They decided they needed to clear a roster spot for Middleton rather than just call up German/Alexy/Padilla. Why keep those guys if they aren't worth calling up?
Why were these guys not on the OD roster?
Burger provides more value than Sheets, and Alberto/Romy are somewhat redundant.
Banks is clearly a better option than Diekman.
