After watching Jason Heyward walk up to the plate and settle in, it would appear almost a physical impossibility that he could ever command the inner half of the plate with any power or consistency. I am certainly no hitting coach, or expert swing analyzer, but it is plane to see that his stance is way to "closed" and his natural first step closes it further as he has a tendency to pick that front foot up just a bit and move it towards third base further closing his stance and thus eliminating his ability to even consider "turning" on a pitch.
I sincerely hope he can figure something out, but it looks like a wholesale change is warranted.....or at least the idea should be considered that his approach and mechanics are stifling his raw talent and power. When I watch a guy like Evan Gattis walk up there looking like Jeff Bagwell, open stance and all.....it is easy to envision him turning on a ball and crushing it, and also easy to envision him staying on a pitch and driving it to center. While I am definitely not comparing the two or suggesting Heyward take a lesson from Gattis......all I mean to say is that when Jason steps into the box, and he collapses that torso and strides towards third base....it seems like physics is his enemy. He seems way too uncomfortable in the box.
