fulcrum Pitching Articles

Here are some pitching articles on this important pitching velocity topic. This topic is currently open for discussion. You can either comment on the articles below or start a thread in the pitching forums.

Pitching Speed And The Glove

There is a lot of controversy around the glove side to pitching mechanics. Conventional Wisdom would coach the pitcher to pull down or pull around the glove side to launch the throwing arm into action. The problem is this would go against pure speed and classic physics.

The reality is that the glove arm to shoulder must act as a fulcrum for the shoulders during the throw to allow for efficient speed mechanics. To understand this we must first define the fulcrum. A fulcrum is the pivot about which a lever turns. The lever in pitching mechanics is the shoulders and also the hips but in this article we are only talking about the shoulders. The shoulders must swing like a door towards the target. Once they open then the arm must launch over the top of the door. If the pivot or fulcrum of the door is moving when the door is slamming closed then the door will not reach its top velocity. The same results would occur with other tools that use the fulcrum or pivot to swing a lever. Good examples similar to pitching, which I have used on this site, would be the catapult or mouse trap.

Tim Lincecum Teaches Top Velocity

There are two forces that add velocity to a pitch:

1. Momentum
2. Rotational Torque

For momentum to effectively transfer to the ball, the pitcher must use all rotational pivots in order from the bottom up.  The hips must rotate before the shoulders and the shoulders before the arm internally rotates. For this to happen effectively these pivots must be free to rotate completely. Notice the picture of Tim Lincecum at the bottom of the page (Tim Lincecum is a phenom because of his size and ability to reach his top velocity continuously.)  Notice in the picture his weight is slightly leaning to his left. This would be like tilting an open door backwards so the open door slams closed due to gravitational forces. This gravitational pull is helping to create full range of motion in Tim Lincecum’s hips and shoulders at front foot strike. If he or the door was tilted the opposite way then these gravitational forces would work against his momentum by decreasing full range of motion in his rotational pivots. Using the force of gravity to increase the range of motion in your hips and shoulders will have a significant effect on your velocity. This is a big reason why Tim Lincecum can throw so hard for his size. He is working with the forces of nature to generate his power. Read more
