Maybe I'm reading you wrong Parker, but I don't think Bert is talking about power. I believe Bert is talking about "directional mechanics". [yeah, I just made that up :-) ] We used to call it, "lunging towards the plate". Step back, square-up shoulders to the plate [sort of], then "power towards the plate". That's the type of pitcher Berrios appears to be. But one size does NOT fit all. Remember Tiant and Holtzman? Anyway, a pitchers delivery is about consistency. And the Twins have a good amount of pitchers that need work at that.
