Free agents

Matt Wieters: The Orioles made Wieters a qualifying offer, and while in the abstract it seems like it'd make sense for him to accept it and try to have a full, healthy season before heading back out into free agency, he's the only everyday catcher on the market this winter. That would seem to guarantee that he'll get several multiyear offers that would make the qualifying offer pale in comparison. Wieters has never reached his full potential offensively and has consistently had poor pitch-framing results, although he's been a good throwing catcher -- at least when his elbow is OK -- and is considered a good receiver.
