Hi guys, first time emerging from a longtime lurk. I'm here to say Castillo tremendously sucks (due to his framing inadequacies, of course), and I think he is unlikely to get much in trade. What he costs the pitchers in strike calls more than wipes out any positive value he provides with his throwing, blocking, or mediocre hitting. The chart in this article shows the avg OPS that results after every count. It looks like one borderline strike/ball call means the difference of somewhere around .300 OPS points (on average, roughly, depending on how deep into the at bat it is). http://www.sportingnews.com/mlb/story/2014-09-15/whats-the-most-important-pitch-of-an-at-bat-mlb-hitters-offer-their-thoughts According to BP, Montero + Ross gained 193 strike calls over actual in 2014, and Castillo lost 102. So compared to Montero+Ross, That's 295 times that Castillo turned the batter into a .900 OPS guy instead of .600. If there were any potential Castillo-suitors left that didn't think about how costly a bad framer is, it seems hard for them to ignore it now, with how obviously the Cubs have banished him for that reason.
