I don't think it's a conspiracy against the Twins. I think it's consistent for all teams/pitchers. Good pitchers get calls, Bad pitchers don't. If a pitcher consistently hits his spots, the zone expands. Many times, for example, the catcher can set up outside, and the pitch goes inside....still a strike, but looks bad when the catcher has to reach...they won't get the call. Not saying I agree with it, but pitchers make their own bed a lot of the time. Especially if they don't have a track record. It's not much different than Mauer getting all of the calls in his heyday. Umps used to just assume Joe couldn't be wrong (not so much anymore).
