I don't think Chapman is getting treated any different than any other rookie. I've noticed over the years that umps squeeze rookies. I don't think they should, a strike is a strike, but those are the realities.
And I thought that ump yesterday was ridiculous. His strike zone was miniscule and affected how the game went and factored into Harang getting torched. And then suddenly he expanded the strike zone for Jimanez in the 5th and 6th inning.
