Michael Busch is a great reminder that sometimes you just need to let guys figure horsefeathers out. He was a complete disaster at 1B to start the season, now he's rating as average defensively. He looked so damn lost offensively for a good chunk of the season and while there's maybe still BABIP concerns there, he's got an .853 OPS for the season and on pace for more than 4 wins this year.
Basically what I'm saying is, stick with Miles Mastrobuoni as your everyday 3B. He's gotta figure it out eventually
(ok I'm not saying that)
