The Balance Points of Tim Lincecum and Brett Sinkbeil 谈论有关"平衡点"的问题 Contributed by Alex Eisenberg Friday, 25 April 2008 By Alex Eisenberg San Francisco Giants pitcher Tim Lincecum and Florida Marlins pitching prospect Brett Sinkbeil aren’t exactly on the same level in terms of talent, but the only thing we are comparing today is what they do at their “balance point”. When a pitcher hits their balance point, they basically stop mid-way through their wind-up to establish balance and then start again as they head toward home plate. This is called a “tall-and-fall” pitcher. 所谓“tall-and-fall”是指投手的投球动作在自由脚抬起之後会在平衡点稍作停顿 然後再次启动往前的型态. When a pitcher "drifts through the balance point”, there is no stoppage in the wind-up. As the pitcher lifts his knee during his wind-up, you see him start to drift toward home plate before ever reaching his balance point. Momentum carries the pitcher toward home plate as he leads with his hips. 用"drifts"方式转移重心的投手,投球动作中不会在平衡点停顿,你会看到当他一边提起 膝盖的同时一边开始移送重心往前,甚至在到达平衡点之前重心就开始移动. 他们是运用屁股引导产生往前的动量. For a better illustration, on the left is Tim Lincecum (drifting through the balance point) and on the right is Brett Sinkbeil (tall-and-fall): 请看图比较:左边是Tim Licecum,Drifts的代表;右边是Brett Sinkbeil,T&F的代表. A pitcher's "balance point" has a lot to do with a pitcher's tempo. Tempo is defined as "the speed in which a pitcher can go from the point to where their knee reaches its upper most point (or when it starts to move downward) to the time of release." Tempo is measured in frames. Lincecum comes in around 21 frames until release, while Sinkbeil comes in around 29 or 30 frames until release. The benefits of drifting through the balance point and a faster tempo are as follows: 平衡点的问题和投手的tempo有关.Tempo是指完成提起膝盖至相对最高点到球投出为止 这个过程的速度.用影片的frames计算tempo,Lincecum是21,Sinkbeil是29~30. 以下是以Drifts方式移送重心以及运用快一点的tempo的优点: 1. Stride Length and Release Point - A pitcher that drifts through the balance point and really gets out in front is more likely to release the ball just a little bit closer to home plate. Drifting enables a pitcher to have a longer stride. Even just a couple inches can make a big difference. Releasing the ball a little closer to home plate allows the ball to get on the hitters faster. The faster the ball gets on a player, the better. 1.跨步距离以及放球点-使用drifts方式并且确实让球在前方投出的投手有机会让放球点 更接近本垒.Drifts会让投手有更大的跨步,即使是几寸的差距也会有很大的影响. 放球点更接近本垒板让球更快速朝向打者,对投手来说当然是越快越好. 2. Velocity - Drifting through the balance point allows a pitcher to build up momentum toward home plate. The pitcher's tempo is increased, their arm is almost forced to become faster and this all adds up to the potential for extra velocity to be added. Now, it should be noted that despite an extremely slow tempo, Sinkbeil does manage to generate pretty solid velocity due to a pretty short arm action among other things. 2.速度-Drifts的重心转移方式可以让投手产生往前的动量.Tempo变快了,会自然地逼使 挥臂速度也跟着加快,所有这些因素综效使投手有获得更快球速的潜力.有一点值得注意 的地方,尽管Sinkbeil的tempo很慢,他仍然能够用他的方式产生可观的球速,因为他精简 的挥臂和一些其他控制很好的因素. 3. Deception - As mentioned earlier, the body is moving faster toward home plate. If a pitcher has a wind-up that looks aggressive and looks as if they are they are about to throw something hard, then as a hitter, you gear up for something fast; until the pitcher throws you a breaking pitch. As a result, the hitter is off balance at the plate. 3.投球隐蔽性-如前所述,Drifts使得身体向前的速度更快.如果投手投球动作看起来相当 勇猛积极好像要丢出猛力的一球,那麽打者便会随时严阵以待一颗火球,直到你投出的是一 颗变化球,使得打者等待在打击区失去平衡. Of course, there are some downsides to drifting through the balance point. For one, not all people are able to do it. Drifting requires some sort of athleticism and keeping all parts coordinated together, so repeating your delivery can be a difficult thing. 当然用Drifts的方式有它的缺点.其一,不是所有人都有能力完成这样的重心转移. 它需要很好的运动能力和协调能力来让所有的动作紧凑,所以要让姿势固定一致相对来说 是一件较为困难的事. Control can sometimes become an issue if the body is moving to fast for the arm to catch up or the pitcher is not consistently able to repeat their delivery. 如果有时候身体移动的太快以致挥臂赶不上或者没办法固定动作会导致控球的问题. However, the positives heavily outweigh the negatives in my opinion. Even if a pitcher has trouble drifting through the balance point, they can still do a better job leading with their hips instead of being so “tall-and-fall”. 然而,我认为正面助益大於负面.即使在drifts方面有不顺畅的问题,仍然可以学会用屁股 导引重心转移而不是所谓T&F. --
