Catching 4 of Berrios' 5 starts probably accounts for most of the difference in catcher ERA. Missing the 2018 team (with bad versions of Dozier, Buxton, and Sano) probably helped the W-L record Numbers lie all the time. As the saying goes, there are three kinds of lies: Lies, damned lies, and statistics. I'm not saying the Twins should dump Castro. The money is already spent, he's a good defensive catcher, and he may still work off the effects of injury and inaction to once again become an adequate hitter (although good is probably too much to hope for at his age.) I'm not ready to put all my chips on the Tortuga phenomenon or on Garver's concussion recovery (and marginal defense), but I would like to ride their current performance a bit more heavily for now.
