>>> I am new to this board, but I have been reading some of the strings. I loved the Final Arc 2 by the way. With all the talk about great hitters and rotational vs. linear, I was wondering, Albert Pujols, Manny Ramirez, Alex Rodriguez are one of the best hitters around to all fields, for power and for average, can we see some clips on them to analyze whether its rotational or linear. Along with Barry Bonds who is in a class by himself, (Steriods or not) These guys are the best hitters in the game for the last 5-10 years. I think we need to see their swings before we can say whether rotational is more productive or effective than linear. <<<

Hi Gerard

Welcome to the site. – You might try - http://www.youthbaseballcoaching.com/swings.html - to start with. There are also clips on the net of most of the hitters you mentioned. But before we can discuss whether they are linear or rotational, we would need to agree on what criteria we use to classify a hitter in those categories.

Some would say that a batter is linear if weight is transferred forward during the stride. Others might say the batter is rotational if he rotates about a stationary axis. Many would argue that most batters are combination of the two since they both stride forward and rotate about a stationary axis.

I will place below a definition of “linear vs rotational” this site has used from its conception in 1999. – I would be interested in your thoughts.

<u>Question/Comment:</u>

>>After 37 years in this game, I have still never figured out what a LINEAR hitter is or who teaches it. I see posts every week about linear vs rotational, but no one has ever given me an explanation or pointed out a book that teaches linear hitting. Who teaches it and what is it. I know what it says in the dictionary. Does any one know?<<<<

Hi Doug

If you have not been a long time visitor to Batspeed.com, it is understandable that you may not be familiar with the Linear vs Rotational controversy. We may not have coined the terms, as 55 speculated, but we were at the forefront in pointing out the difference in the two terms. Therefore, I will try to give a short, clear definition of the two mechanics.

Linear mechanics has been taught by most (probably 98%) of the batting instructors for decades. “Linear” refers to mechanics that promote an inline (A to B) thrust of the hands straight back at the pitcher. It may be referred to as “quick hands”, “knob to the ball” or similar batting cues where the muscles in the arms are mainly used to accelerate the hands away from the back-shoulder toward the pitcher.

With Rotational mechanics, the muscles in the arms are not used to accelerate the hands. The hands stay back at the shoulder and are swung (or flung) into a circular path by the rotation of the body. --- The bottom line --- Linear mechanics produce a straighter hand-path – Whereas, Rotational mechanics produce a more circular hand-path.

Why does rotational transfer mechanics out perform linear mechanics? – Because there is a “pendulum” effect that accelerates the bat-head when the hands are taken in a circular path. There is no “whip” or “pendulum” effect that occurs from a straight extension of the hands.

Note: Regardless of the length of stride, all good hitters rotate around a stationary axis. Therefore, length of the stride or amount of weight shift has little bearing on whether or not a batter is Linear or Rotational.
