When I was taping games for my study, I noticed that when a home run was hit, they often followed it by showing an across-the-plate-view replay of the swing. After a couple of years, I had over a hundred of these swings on one tape. A good 75 percent of these across-the-plate views showed the back-elbow in the “L” position similar to the Sosa clip.

> I agree that some hitters do have the back-arm more extended. And as grc pointed out, even with good rotational mechanics, the arm is also more extended when pulling the ball or hitting outside pitches. However, when most of the best hitters hit the ball to left or right center, the elbow is still back in the “L” position at contact.

I would ask the reader to advance these clips frame-by-frame until the bat becomes perpendicular to the path of the incoming ball (hitting the ball more straightaway) or to contact (not the frame after contact where the ball has left the bat) --- The clips are there, you be the judge.

HI Jack,

The first video proved my point. Bagwell is extending at contact, he is in the L with the ball still out front and then extends as he makes contact.

Guerrero is more then likely hitting and inside pitch and just turning into the ball. He is still in the L position because he hitting an inside pitch.

Bernie Williams looks like he is pulling the hands in to hit an inside pitch, so he is still in the L position.

Griffey is extending as he makes contact, the ball is still out front when he is in the L position.

Mcgwire is extending at contact.

The only two player whoe in the L are both hitting inside pitches. You don't extend to hit inside pitches, you turn and stay inside the ball.
