标题Re: Pitching Mechanics: Hong Chih-Kuo
时间Wed May 20 20:45:24 2009
※ 引述《abc12812 ()》之铭言:
: http://tinyurl.com/p5ng8b
: Hong Chih-Kuo is a flamethrowing lefty who routinely gets his fastball into
: the mid-upper 90's with the Los Angeles Dodgers. These stats don't lie - Kuo
: is a great pitcher, when healthy. Of course, that's the problem - Kuo has
: suffered four surgeries on his throwing elbow.
: A closer look at his pitching mechanics follows after the jump...
: Kuo takes his throwing arm laterally behind his body quite a bit - better
: known as "reverse rotation." When he returns it to the throwing side, it
: causes a serious case of forearm flyout, which causes his olecranon process
: to slam into its fossa and do serious injury to the elbow.
: Kuo is pretty quick to the plate - 18-19 frames from maximial leg lift to
: footplant, which is good. However, he also has serious timing issues at
: footplant - check the still frame at the top of this article, or watch the
: animated GIF a few times. It's clear that Kuo has late forearm turnover and
: this causes unnecessary stress on his pitching elbow as it lays back in
: external rotation.
: Kuo has the "elbow lift" arm action, which is often referred to as a "short"
: arm action (and loved by many traditional scouts), causing him to
: horizontally flex the shoulder joint and stress the anterior portion of his
: shoulder.
: I don't know how many more surgeries Kuo can take, but if the definition of
: insanity is doing something the same way over and over again and expecting
: different results, Kuo might very well be on his way to the crazy house.
刚看到朋友转的这篇文章
这篇可以跟我自己blog的分析一同服用
http://blog.xuite.net/johnason/milktea/3779424
并且做个比对
我个人对他的分析有以下看法
他里面提到的reverse rotation跟我的观察一致
我也有在我那篇文章提出这点
但是我认为这个动作是他威力的来源
加速过程需要的是时间与空间
Kuo进入发射动作前利用reverse rotate让他能够给球更多的加速空间
他手臂的柔软度给与了他这个额外的加速空间
是让他拥有世界顶级的速球品质的主要原因
配合我在道奇板(
#18uDZ8ma)去年kuo受伤时的文章一并服用
他是否解决去年组织沾黏的後遗症(降低柔软度)
以至於让他无法负担这个动作
才是该了解的
至於footplant这部分我觉得有点不知所云
他挑了背後的连续动作gif来解释这点
然後说读者可以用文头第一张静止图来比对....
这个动作应该用sideview吧
Kuo也不太能被分类为short arm action
这也与第一段的reverse rotation矛盾
以上
