Basically, these guys have such fine tuned biomechanics for hitting a baseball with just a few hundred milliseconds to decide wether to swing and where to swing, that trying to change their approach to hit further down the bat might ruin their hitting if they mess up. Far easier to shift the sweet spot. Its not that they just need to get closer to the ball, their estimation if where a ball will strike their bat is slightly off.
