His fastball is awful right now. He routinely leaves it up in the zone and it has very little life to it. Pitching from the stretch seems like it affects his ability command it down in the zone consistently. His slider also looks nothing like what he showed the 2nd half of last season. It's lost bite, and I'm sure theirs a Stat/metric to measure its disparity from last year. Hutch is struggling big time, and assigning luck as its reason for said struggles is what I take issue with.
I'm kind of excited to see how exit velocities off the bat translate to player evaluation, I think adding these new metrics might help to better explain how guys like Buehrle can be successful. One thing is for sure, it's definitely not mostly luck based as you seem to think.
