Carlos Gomez写了一篇关於两人的比较 作者在他网页放了两人投球动态图分析对照， 相当值得前去一看 http://0rz.tw/5433S 这篇分析有点长度，我只挑重点翻一下 文章可能还是要配合图看 图有很精细的比较 First impressions: Buchholz vs. Kennedy 让我们来看看这两个孩子 八扣子 vs. 阿甘 Clay Buchholz has made two major league starts. In case you haven't heard, one was pretty good. Ian Kennedy has made one major league start. In a Draft Review I wrote last year, I said this about Kennedy: 八扣子已经在大联盟先发两场了，有一场投的相当理想 阿甘则是先发过一场了，我记得我去年写下关於阿甘的一段： "Another guy with outstanding arm action. Throws to a firm front side, which again helps ward off shoulder troubles. A guy in the Prior/Reyes mold although he has better tempo than Prior. A good pick here. He looks very polished. 又是个拥有杰出手臂动作的家伙，稳定的身体前侧投球，并且避掉肩膀的麻烦， 这孩子有Prior/Reyes的模式 而且有比 Prior更好的节奏， 他看起来是那样的闪闪动人，真是好物.... I followed up that favorable review by answering a few readers' questions (in the "comments" section) in which I addressed Kennedy: 然後我接着回答一些读者的问题 谈到阿甘： "A guy who I'm starting to like more and more is Ian Kennedy. The more I watch the video, slow it down, the more I'm intrigued. I'd bet you really like his delivery. If you haven't checked it already, go ahead and check it out." "If your mechanics look like Kennedy's, you're OK with me...." 我越来越爱阿甘了，我越看影片，把它放慢看，我就越被他迷住 (靠 这一段好西斯) 我确信你也会爱上他的投球，如果你还没看过，紧去看阿... 如果你投起来跟阿甘很像 你也能够让我爱上.... Are three starts and a couple of draft videos enough of a sample to determine which pitcher you'd rather have? Probably not. But it's sure gonna be fun to try. 三场先发跟几支录影带就足够影响你对投手的想法吗? 也许不能，但试试看吧，挺有趣的 Today, we examine these pitchers' mechanics, approach and stuff to try to answer the question: Buchholz or Kennedy? 今天我们检测这些投手的投球技法，路径跟球种威力，来试着讨论是八扣子还是阿甘屌? Two very different deliveries 两种不同的投球 Let's highlight some of the major differences: 让我们来看看一些主要的不同点： 1)八扣子身体放的更低，比阿甘更有效率　 2)另一方面呢，阿甘则有比较好的手臂动作 3)谈到手臂的放球点，阿甘从相当完美典型的四分之三放球点投出 4)两位投手完成动作都很不赖，不过我会给阿甘加点分，因为他优异的身体前侧投球技法 5)八扣子放松之後手掉太多，虽然掉的幅度不是很大，但意味着阿甘还保持住比较好 的防御位置。 那为什麽八扣子手会掉呢?　一般来说，当头往那里，身体就会随之而行。 关於投球技法的话题先打住，来谈谈球种威力： Fastball 快速球 阿甘快速球通常在89-91麦，偶尔有到92麦，而八扣子的速球大概在90-93之间，大概 是因为他的身体放的够低，阿甘的快速球有着更佳的横向移动，两位投手的快速球都 属於"飞球型"。 Curve/Slider 曲球/滑球 两位都有这种球路，八扣子的曲球变化大且相当恶心，阿甘的则没那麽变态，差不多是 滑曲球那样的幅度而已。这两人面对打者的解决方案也不太一样：阿甘大部分是让打者 "挥棒落空"。 而八扣子的策略是，当打者预期是快速球时，会来颗大曲球冻结打者。 1) Buchholz' lower body is more active than Kennedy's. Even though their tempo looks similar, you can clearly see how much more energy and momentum Buchholz carries into footplant. Kennedy is more of a "tall and fall" guy and glides into footplant more passively. Both pitchers take 25 frames of video (at 30 frames/second) from the time each gets to the top of his knee lift to the time they release. Buchholz has a higher leg lift. Simply put, he covers more distance in the same amount of time (meaning he has better body speed). Buchholz leads with his hips better as well. He does so while keeping his back shoulder over the rubber, creating a different "shoulder tilt." This tilt matches their respective release points, as I'll show you later. As I mentioned in my Draft Awards article, I call that "the move." This is what I mean...(and yes, I know the camera angles are different). (见附图) Buchholz has the more aggressive body move I prefer. 2) On the other hand, Kennedy has better arm action. He loads the scapula better, seems to have better elbow external rotation, and just looks "whippier" than Buchholz's arm action. Here's a clip: (见附图) 3) Speaking of arm slot/release point, Kennedy throws from a pretty typical three-quarters release point. Buchholz' high arm slot resembles an Iron Mike Pitching Machine. Check out these stills: (见附图) I'm not a big fan of changing pitchers' release points, but I prefer Kennedy's for one simple reason. In terms of command and rotational efficiency, a pitcher is better off not moving his head out of way to make room for his arm. You can clearly see how much more head movement Buchholz has in the few frames leading up to release. I do think Buchholz' release point adds to his deception and works for him, as I'll explain later. 4) Both finish their pitches very well, although I'd give the slight edge to Kennedy because of his superior front-side mechanics. One of the very noticeable traits of "Tom House" mechanics (think Mark Prior and Randy Johnson) is how well they firm up the glove side and "tighten up" to prevent them from "pulling off the pitch" and to get better "extension." In the still picture above, notice the position of the glove and the lead arm elbow. Does it not look like Kennedy is "out in front" more? Speaking of Tom House, it used to be that you could tell who was a "Tom House guy" by noticing a pitcher's front-side mechanics and (unfortunately) his passive lower body (the whole "tall and fall" thing). Fortunately, I now hear that he advocates more of a momentum/tempo-based approach with a more active lower body. 5) Buchholz falls to his left after release. Not a biggie, but it puts Kennedy in better fielding position. Why does he fall to his left? Generally speaking, wherever the head goes, the body will follow. Let's step away from mechanics and talk about their stuff... Fastball From what I've seen so far, Kennedy's fastball comes in 89-91 mph with the occasional 92. Buchholz's fastball (probably because of his better lower body mechanics) has a little more zip to it as it comes in at 90-93 mph with the occasional 94. Mostly due to their respective release points, Kennedy's fastball has more lateral movement (in to righties) than Buchholz' almost straight over-the-top fastball. Due to truer 6 to 12 backspin (again, think release point) and better velocity, Buchholz' fastball has better "hop" at the end. Both pitchers' fastballs are "fly ball" fastballs. Curve/Slider Both pitchers throw a curve and a slider. Buchholz has a nasty, big-breaking and a more 12-6 type of deuce. Kennedy's curve has a smaller, slurvier break to it. He seems to favor his slider/slurve over his curve, while Buchholz certainly uses his curve more than his average slider. Kennedy's breaking pitches are more of a "swing and a miss" variety while Buchholz is better able to use his big curve to also freeze hitters expecting a high fastball. I'd like to point out again how their release points come into play here. With his higher release point, Buchholz is probably better off by sticking to his big, sharp curveball. Kennedy is better suited to throwing a slider/slurve that starts on the same (flatter) plane as his fastball and changeup. I've done a few voice-over video analyses that talk about releasing pitches on the same plane and their effect on hitters. 有错请指正:) from :http://www.hardballtimes.com/main --
