SECTION1-1

~Essential difference~

I classify hitting mechanics into two types, depending on how they generate the power to accelerate their bats. Since each of those two types has completely different mechanics, they require different hitting drills, tips, and instructions respectively. Even suitable tools and tactics are different too. Therefore, understanding which type you are employing is crucially important.

I named one puncher type and the other swinger type.  Movie1-1(a) and movie1-1(b) shows typical examples of those two types. This is not an innate difference. Which type a hitter chooses is decided by acquired factors such as coaches who taught him and star players who had influences on him. There are definitely not any innate differences between puncher-type hitters and swinger-type hitters. So you can change your hitting mechanics from now on by learning their different mechanics.

Movie1-1(a): puncher type hitters

movie1-1(b): swinger type hitters




First of all, I want to introduce two experiments for understanding the core systems of swinger- and puncher-type mechanics.

(1) Experiment for swinger type (movie1-2)

Movie1-2: swinger experiment


Like figure1, stand with your whole body relaxed, letting both arms down. Then, rotate your hip, using the momentum of weight transfer. By doing so, your arms will swing around your body by centrifugal force. In other words, you need not to swing your arms forcibly with your upper-body muscles.

Figure1: Experiment for swinger type  


Examples of swinger-type hitters: Hank Aaron, Ted Williams, Joe DiMaggio, George Brett, Willie Mays, Babe Ruth, Darryl Strawberry, Eddie Murray, Randy Bass, Tony Gwynn, Josh Hamilton, Joe Mauer, etc.
















(2) Experiment for puncher type (movie1-3)

Movie1-3: puncher experiment


Like figure2, make a stable and wide stance, squatting down to some extent, and put your top-hand in the launch position. Then, throw a punch directly from there quickly and suddenly without any preparative motion such as back swing, weight transfer, and separation. Generating your maximum power like an explosion is very important. You should not use your lower body intentionally because it works automatically when you try to accelerate your punching arm. Specifically, weight transfer and hip rotation occur automatically when you try to throw a punch.

Figure2: Experiment for puncher type 


Examples of puncher-type hitters: Mark McGwire, Derek Jeter, Barry Bonds, Mike Piazza, Jose Canseco, and most of today's hitters in MLB.




To make a long story short, swinger type uses weight transfer, body rotation, and front-arm-pull. On the other hand, puncher type uses explosive muscle contraction and rear-arm-push


Figure3: Swinger type uses front-arm-pull. (Babe Ruth, George Brett.) 




Figure4: Puncher type uses rear-arm-push. (Miguel Cabrera, Barry Bonds.)
