Definitions Page 1

A to C Pathway: A model used to illustrate the hand path to the ball while using a short, compact swing. Imagine a right triangle, with one vertex at the launch or hitch position called “A”. A second vertex, position “C”, would be at contact. The hands should travel down the hypotenuse of the triangle, straight to the ball, or “A to C”. Should the hands venture out to the “B” area, they are not taking a path straight to the inside of the ball and are said to be “casting”, which adds length to the swing.

acceleration: The rate of change of velocity. In layman’s terms, the bat head would be “speeding up” through contact.

angular velocity: A term used to describe the velocity of an object that is rotating around an axis. In hitting, we are primarily concerned with the angular velocity developed by the bat head caused by both linear and rotary body actions.

athletic position: A term used to describe the “ready position” of any number of sports. The feet are outside the width of the shoulders, knees flexed, weight forward on the balls of the feet, chest up. The athlete is balanced and is now ready to make an athletic move.

back foot: The foot away from the pitcher, while taking a stance in the batter’s box.

back hip commitment: A term used to describe the back hip action as it forcibly rotates toward the pitcher to a position under the torso during the swing. The linear action of the weight transfer is halted by the firming up of the front side. Pivoting on the back foot and forcibly driving the back hip under you causes rapid rotation of the trunk. This transfers force from the ground up, out through the chest, arms, hands, resulting in increased bat speed.

backside: A term used to describe the side of the hitter that is away from the pitcher while taking a stance.

backside collapse: A phrase used to describe a hitter who fails to pivot on the back foot properly, resulting in lack of back hip commitment, and poor weight transfer. Normally, this results in a high front shoulder, producing an uppercut type swing plane.

backside hitting: A term used to describe the direction of a batted ball in which the hitter drives an outside pitch to the opposite field. i.e. right-handed hitter hits the ball to right field.

backside under you: see back hip commitment.

balance: A term to describe a state of equilibrium of all parts of an object about it’s center of gravity.

balance, dynamic: A term to describe an object in balance while in motion.

balance, static: A term to describe a stationary, or non-moving balance.

barred arm: A term used to describe the front arm extending, or “locking out” too early in the swing. This generally results in the hands being forced away from the body, or casting. This causes the front shoulder to fly open to early. Consequently, the hands lag behind, and the barrel takes a long, sweeping and/or looping path to the ball.

barrel: The large end of the bat where contact should be made.

barrel above hands: A term used in teaching that describes the position of the barrel in relation to the hands as it approaches the ball. i.e. keep the barrel above your hands.

barrel up: A phrase to instruct a hitter to move the bat to a more vertical position. The term could also have a similar meaning as barrel above the ball.

bat: A long rigid simple machine that is used to apply a force to a ball when struck. A bat is considered a third class lever which is favored for developing speed at the barrel end of the lever. By proper use of body actions, in coordination with proper hand action, the bat can develop tremendous velocity. An example of a first class lever would be a long pole and block used to lift your car out of a ditch which is favored for developing power at the end lifting end. A bat consists of 5 major parts: (1) knob, (2) handle, (3) grip, (4) barrel, (5) end cap.

bat angle: A term that is used to describe the angle formed by the bat and a horizontal line.

bat, flat: see bat, horizontal.

bat, horizontal: A term used to describe a bat position that has no bat angle and is parallel with the ground. Starting with a horizontal or flat bat can lead to problems in the swing. A horizontal bat places the center of gravity well outside of the hands. In younger hitters who are weak physically in their hands, wrists, and forearms, gravity pulls on the heavy barrel end creating a torquing effect, causing the knob to lift, and the barrel to drop. Consequently, as the swing begins, it’s difficult to get the knob going downward toward the ball. The hands move away from the body in a casting action, beginning a long, sweeping swing.

Bat Mass (weight): A term used to describe the weight of a bat, usually measured in ounces.

bat path: A term used to describe the path that the bat takes during the approach, through contact, and follow-through. Normally the bat path is described as “inside-out”, or “outside-in”.
