Good comment. I consider myself both a hardcore fan and a casual fan…
As a hardcore fan, no I do not actually understand this trade. It’s like robbing Peter to pay Paul. The pitching side gets better, but the hitting side gets worse. Potentially much worse. Guys like Arraez don’t suddenly lose their bat-to-ball skill. If someone is going to claim that Arraez’s knees are going to affect his performance, then that same someone should be consistent and admit that Lopez has a flaky shoulder himself, and that Salas’s stats look pretty ordinary, and the third guy they got is not old enough to shave yet. Some people here are really low on Lopez too. I don’t know; I guess I like him? but I will just say that I noticed that his shoulder problems have correlated fairly closely to his trade to Miami several years ago and subsequent increase in velocity. If the Twins want to keep Lopez dialed up at mid-90s and also keep him healthy, then maybe the philosophy of five innings and done will actually be a benefit to this particular guy. Less chance for wear and tear every fifth day if you pull him out after 5.
The front office just signed Correa, overpaid for Correa. Why burn that goodwill? The front office made their lineup much better by signing Correa, then made it worse by trading Arraez. So no, as a hardcore fan, I don’t really get it on a rational level.
Your second part about me also being a casual fan, however, is correct.
All that said, I am glad there are people who like this trade. The Twins need you and Twinsdaily needs you! Stick around and talk about it!!
