Alcala, Stewart, Thielbar all hurt. Sands ineffective. Henriquez just back. De Leon hurt. That's 4 decent to good RPs hurt, and two that likely aren't that good, though Henriquez at least intrigues me.
Look, we can look at all the anecdotes we want, but Gleeman has posted very compelling stats. Pagan has been the worst RP in baseball for four years when it comes to adding value in indiividual games and relative ERA. There is no reason to have him on the roster. He's PROVEN to be bad for four years now.
I don't care which minor leaguer they call up to replace him. That person has not proven to be the worst in baseball. WInder and Balazovich should be in MN, either thriving or failing. This team is NOT a good team, so find out what those two have. Put them in positions of stress, and see what happens.
