Well I have already posted that I thought Sanchez and Alfaro was too high a price to pay for Realmuto, now that the deal is done, I have to hope the Phillies brass knows more than I do. I am sure they do, but I still consider the price for Realmuto as being a very high one.
On a positive note, Realmuto should be an upgrade over Alfaro in 2019 and 2020. Sanchez has not thrown all that many innings in his 3 years in the system and has had significant arm problems this past season. He has tremendous potential but he may never reach it. I have read reports that the Phillies seem to have soured on him somewhat this off season. Again, I have to rely on them knowing more than I do.
Defense really hurt the Phillies in 2018. Adding a full time regular shortstop and moving Hoskins to first base, replaced by a real outfielder in left, project to greatly improve defense. Another area that really hurt in 2018 was what seemed like an enormous number of passed balls. I hope Realmuto will reduce this in 2019.
I think the Marlins got a very good return for Realmuto but like most deals, it might look different in a few years. For now, Realmuto is a Phillie and I am looking forward to watching him in 2019.
