I thought this was kind of an interesting observation:
I think what they're talking about here is where the bat head enters the zone. Some hitters, like Haniger, gear their swing so that the head of the bat enters the zone slightly farther back in relation to the plate and the hitter's body, and the idea is that this gives you an extra millisecond or two to adjust the path of the bat to meet the ball. Haniger actually reworked his swing in the minors for that purpose. Someone, probably Divish, wrote about that this last summer I believe.Locklear has some stiffness to his swing and his bat moves in and out of the zone quickly...
With Locklear, I think what they're saying is that he kind of does the opposite, that he goes direct to the ball. I imagine the approach that's most suitable for the individual depends on all sorts of variables including vision and pitch recognition, hand-eye coordination, bat speed, and probably some subtle issues around anatomy like height, arm length, torso length, etc. I personally like the Haniger approach just because it seems like the most logical way to go about trying to hit the ball, but I'm also so far out of my depth that I couldn't possibly say that one way is better than the other.
