The issue I expressed with Castro is that while his framing numbers are impressive, part of framing is having quality pitchers near the plate a lot where they get the benefit of the doubt. Huge difference between Astros pitching staff and ours. A day or two later, Cameron expressed the same concern in his chat. He wrote, 'If the team that employs Mike Fast isn’t interested in bringing you back, maybe your framing value isn’t as likely to continue as the Twins are hoping.' So, he doesn't have a very good arm, isn't really good at blocking balls, and isn't good that good at the plate. If his framing drops, people may be disappointed. Worth the shot, I'm glad they took a shot, but still. A lot of people seem to have issues with Kepler's defense. Not sure if it's because he's lanky or not but Kepler has impressed me with his defense. He's above average out there. I'd feel comfortable with him in CF too, to fill in for Bux on an occasional day off if needed or if Bux got hurt. Bux is awesome on D, of course. Rosario was shaky on D last year. Made fundamental and mental mistakes a bit too much and didn't seem to read the ball as well either. Took a step back on D, IMO. As far as our IF defense goes, Dozier is average and Mauer is above average. The rest is hard to watch (though I don't think Polanco is quite as bad as others do, but metrics disagrees with me).
