The Twins are the slowest at promoting position players, or at least they were pre-2011. Then they decided to have their best prospects skip AAA altogether. Doesn't work (only for Arcia would it make any sense). Chris Herrmann is stagnating. Josmil Pinto is as well. Maybe Matthew Koch would do better if he was promoted (I wouldn't overlook the letdown that players experience when they are blocked, blocked, blocked) Rene Rivera is not worth keeping catching prospects from progressing. I don't like the Twins currently trading one pitcher for one pitcher. I do NOT get the Escobar involvement in this trade. Pedro Florimon, James Beresford, and Danny Santana may ALL be better overall than this guy.
