Josh Donaldson discussed his swing with Mark DeRosa on MLB Central.
I highly suggest watching the whole segment, but here are some quotes that I picked out from it:
“It all starts before you get into the load. Having your natural flow, your natural rhythm.”
“Got my weight into my back heel, which is going to allow me to stay balanced into my back hip.”
“I never want to think about my hands going towards the baseball.”
“Once I begin to go forward, that’s when I begin my load and start to create my angles.”
“If my front foot never opens, my hips can’t ever separate from my upper half.”
“Now in order to hit pitch heights, it’s all about shoulder plane.”
