Great article on staying inside the ball.
In the last 25 years, as further biomechanical studies have been done and video technology has improved, Williams's emphasis on rotational power and Lau's emphasis on linear power—they were both right—have blended to create the modern swing. To understand the overriding theme of current hitting theory, ask the three hitters today who are best at getting on base what the most important element of the swing is.
The Tigers' Miguel Cabrera (.452 on-base percentage, best in the majors): Stay inside the ball.
The Reds' Joey Votto (.434, second): I always try to stay inside the ball. I try to make sure when I make contact with the ball it's not topspin or carved—it's coming off true.
The Angels' Mike Trout (.430, third): The biggest thing is staying inside the ball, using my hands. That's the key for any guy coming up—patience to stay inside the ball and not trying to yank everything down the line.
He did on this ball:
Here's how I'd describe this, feedback welcome.
Trout is not hitting the inside seams, but hitting behind the ball. But his hand path is inside out.
Also note that he is not 'long through' the ball here, does not get extension. Makes me think long through is not so necessary on inside pitches like this, when you're hitting behind or even around the ball (with an inside-out, short-to-the-ball swing).
