I get that folks are upset to see Arraez go, I am too, but if we remove the emotion or "fan" glasses from the situation and consider the context of the move, etc. then it makes clear that this is a pretty good move for the Twins.
Arraez was a joy to watch, but let's face it, he was an undersized, positionless, slap hitter, with bad knees that has battled injuries every season.
I think some of you are underselling how good Pablo Lopez really is. The guy had a 2.92 ERA last year if you remove his starts against the Mets (for whatever reason, the Mets REALLY had his number last year).
This stretches the rotation even deeper and for the first time I can remember, we have 5 LEGIT starting pitchers (I know non of them are aces).
We also add a top 100 prospect that likely slides into a top 5 spot in our organization.
