The Cubs signed former Seattle catcher Luis Torrens to a minor league deal. There's probably a nonzero chance he's the best offensive catcher we have going in to the spring.
And that chance is close to 100% - last year he OPS'd close to .700. 700!
The problem is Torrens isn't really a catcher at the major league level, he's a DH. He's an emergency catcher in effect.
