Don't look now, but Welington is already the 5th all-time best catcher for the Diamondbacks. That's remarkable in a couple ways.
When the Diamondbacks traded for Welington Castillo this season, he wasn't the focus for fans in Arizona. Instead, people focused on the fact that a team actually wanted to acquire Mark Trumbo, and that they gave up multiple living people in return. Sure, there was some pushback about Dave Stewart commenting on trying to fill the catcher need, but in Arizona the trade was really about subtraction, not addition,
Except a funny thing happened and Welington turned out to be pretty good.
