Deep, 15-second Google research tells me that Beef's defense is, to quote the internet, "weak". But maybe getting better? http://www.mlbtraderumors.com/2016/08/diamondbacks-considering-welington-castillo-extension.html Notably, Castillo has made strides with his defensive work this year, according to Baseball Prospectus’s catcher ratings (subscription required and recommended). He has typically graded as a solid blocker while registering good marks with his arm. And Castillo has also improved greatly as a pitch framer; once one of the game’s least-regarded framers, he now registers as average to slightly below-average (with StatCorner valuing him higher than does BP) at winning strikes for his pitchers.
