I find it a bit funny that he gets only a shared rookie card in the base set, but all sorts of inserts.
Baez has been pretty good since being recalled on September 1. I'm starting to be a Baez believer again. All the strikeouts last year really turned me off. He's shown more discipline this year had he's also been really good with the glove.
His season got off to a rough start. He didn't make the Cubs out of spring training and then his younger sister died. It's a pretty heart-warming story, him and his sister. Read about it here. Her death really affected him and when he came back from bereavement leave, he promptly broke a finger. Once he was finally healed emotionally and physically, he's been doing quite well.
