(之前很仔细的翻到一半，然後p1大当机　囧 没想到修好之後竟然连暂存档都不见了 现在生气要乱翻了XD) http://www.hardballtimes.com/main/article/the-new-and-improved-josh-beckett/ The New and Improved Josh Beckett by Carlos Gomez May 30, 2007 In case you've been away for awhile, Josh Beckett is having a pretty decent season so far. Many have tried to explain why. Is it his mechanics? Pitch selection? Better command? Confidence? Better velocity? Luck? Beckett今年投那麽好，为什麽呢？　投球动作改变吗？配球策略改变吗？ 还是更好的控球？更多的信心？或是更快的球速？ 甚至...只是运气..? Today, we examine his mechanical changes as a possible reason for his strong start. 来来，今天我们来看看，他投球动作上的改变是否可能是优秀表现的因素呢？ TEMPO 给我一点Tempo If you have read my work here at THT, or at Baseball Think Factory, you know that I love to talk about tempo. I wrote about how Mark Prior's tempo changes may have had an adverse effect on his arm action. 如果你有看过我在THT或是棒球想法工厂的着作， 你就会知道我有多爱谈论投手的节奏，我写过Prior投球节奏上的改变， 可能对他的手臂动作有不良的影响。 "For Prior however, the more deliberate pace has altered his arm action....His arm action has gotten longer because it has to compensate for his slowed down pace." Prior的手臂挥动速度变慢，以配合他减缓的节奏 My Mark Mulder analysis also includes a healthy dose of tempo talk. 关於探员的分析，也差不多 You get the idea, I like to talk about it a lot. 你得到他了，我爱谈节奏 I prefer pitchers who maintain a quick tempo to home plate and keep their momentum going without interruption or hesitation. As a rough measure of tempo, I measure (in frames of video) the time it takes a pitcher from the time he's at the top of the knee lift to the time he releases the ball. Some have suggested that Beckett has slowed down his motion in order to be more "in control" of his body. In Beckett's May 8 start against the Blue Jays, NESN treated us to a split screen showing how, in fact, Beckett is indeed more deliberate to home plate than the 2006 version of himself. 我喜欢投手维持一个快节奏，在动作之中不要有停顿， 我从投手抬腿到最高点(这让我想到Arroyo)到出手那段时间去计算， 有些人建议Beckett减缓他的节奏，以取得「对他身体更多的控制」 在Beckett五月八号的先发中，NESN作了以下的撷取画面。 从（原文中的画面）可看到，Beckett在去年的投球动作， 其实是花费比较久的时间去投向本垒的。 I needed to find out for myself 找答案 The following clip shows Beckett throwing six fastballs, all clocked between 94 and 96 mph. All but one were glove side (outside corner to a RH). The first three clips from left to right are from 2006. The last three are from 2007. All the clips start from when Beckett begins lifting his left heel on the way to lifting his left leg. By the way, I realize that the third clip has a few missing frames. It's not a big deal in this case, as you'll see. 六个分割画面中，Beckett投出六个快速球，每个都在94~96之间， 只有一个没投到捕手要的位置，（投到右打者外侧) 左边三格是去年的画面，右边三格则是今年的。 都是从他抬腿至最高点开始撷取， 然後第三格有少掉其中几个画面，但问题不大。 Disclaimer: I was surprised too. 我也很惊讶 As you may have noticed, the 2006 clips are from the end of last year. Like many pitchers, Beckett tinkered with his mechanics during the season last year. Consider this clip comparing Beckett in May of 2006 to May 2007. 也许你已经注意到了， 以去年来说， Beckett和许多投手一样，在投球动作中有许多多余的部份。 As you can see in this clip, the speed of Beckett's entire delivery (from heel lift to release) is almost identical. 整体投球动作速度差不多 I don't know which clips NESN used to do their comparison, but in my analysis, I could come to the conclusion that Beckett is actually quicker with his entire delivery this year. In other words, he is less deliberate. OK, so I'm right and everyone else is wrong and that's that. He's quicker this year, so that makes him better, right?...... NOT SO FAST 在我的分析看来，Beckett今年的挥臂速度较快， 所以说，其他人（建议他放慢节奏）都错了？只有我对？ 是这样吗？ Although I believe that how a pitcher gets to the top of his knee lift is important, tempo to me (generally speaking) is from "top of the knee lift to release." That's where it counts, to a certain degree. That's really where a pitcher should start picking up his speed to home plate. This clip, comparing Beckett late last year to this year, is synchronized to release. 虽然我相信， 一个投手将脚抬至最高点这个动作很重要， 节奏对我来说，就是从抬腿最高点至释放瞬间， 这才是投手该开始加速的瞬间， 而就去年和今年，他几乎是在相同瞬间释放。 You could argue that since the '06 version is starting with a slightly higher leg lift, he has to be quicker than the '07 version in order to "catch up" to him at release. At most, '06 might be half a frame faster than '07. From frame seven on, both Becketts are nearly perfectly in sync. Even though he breaks his hands a tad earlier in '07, notice how his arm action is nearly identical. Unlike Mark Prior, his slightly slower tempo has not affected his arm action or the way his body drives forward in a significant way. 你也许会说，去年的抬腿较高， 所以他比较有更快的加速以赶上释放瞬间， 去年的画面中，Beckett的动作几乎比今年的画面快了半格， 今年的动作略慢了一些， 不过跟Prior不同，节奏上的减缓并没有影响他手臂的挥动 My point is that I believe Beckett's "tempo," "speed of his delivery," or "being more deliberate" have not had any significant effect on his mechanical efficiency this year. I'm sorry to those readers who were expecting me, a tempoholic, to come up with a better conclusion than that. Beckett's tempo, when it counts, is nearly identical. I know, I know. You just spent several minutes of your life reading about something that I believe is not a factor. Hopefully, I haven't lost you yet. 靠盃， 作者的结论是整体来说，释放点相同，节奏快一些， 但这些其实没有造成太大影响， 然後他为读者花时间看这篇废文道歉.. （靠，那我花那麽多时间翻是冲啥...~"~ 一直觉得他上面讲话根本是互相矛盾) Let's get to what I do believe is making a difference. Here's a still picture of the first frame of the most recent clip: 好，让我们来看看还有什麽不同 1) Note his hand and glove positions. 注意他手套的位置 2) Check out how his left leg and foot "wrap around" his right thigh in '06 a la Duaner Sanchez (You know I'm a mechanics geek when I can point to Duaner Sanchez's mechanics). Go ahead, stand up. Lift your leg and attempt these body positions yourself. Which one is easier to accomplish? In which of the two positions do you believe that your body is more "together"? 站起来抬腿看看， 去年和今年，哪一个动作比较容易作？让你的身体动作hold住看看 3) The angle from where these clips were taken are not completely identical. However, they are pretty damn close (which is why I chose them in the first place). That said, can you see how '06's upper body is tilted more towards the first base side? 你可以看到，去年投球时， Beckett的动作是比较朝向一垒侧的吗？ What am I getting at? If I could group these adjustments into one central idea, what I would say is that Beckett is doing a better job of keeping everything closer to his center of mass. You might hear the baseball term that he's "gathering himself" better. By keeping his torso, his hands and his legs closer to his center of mass and staying more "compact," Beckett is able to control his body better into an aggressive forward drive into release. Beckett今年在控制他的投球动作中， 将力量留住，重心保持　这部份做得很好 这使他更能控制自己的身体， 并在释放球的瞬间更有侵略性。 Other Changes 其他改变 1) Beckett has also significantly simplified his mechanics. While I admit that I like the May 2006 version of Beckett the most (refer to the second clip), it appears that eliminating excess movement (specifically, the hands over the head windup) has simplified his delivery. Fewer moving parts means fewer things that he needs to coordinate. In theory, it should translate into better command of his pitches. 动作简化，减少出错机会，控球更好 2) While I need to do more research on this, it appears that Beckett is employing a slightly higher arm slot on his two-seamer. As I explained in my Carlos Zambrano article, a slightly higher release point on a two-seamer generally results in a sinker that has less lateral movement but sharper, later, and "heavier" sink. I'm not sure if John Farrell, the Red Sox pitching coach, is an advocate of higher arm slots or not. However, based on what I've read about him, I am fairly certain that he advocates that pitchers use a more north-south approach ("throwing downhill") which is generally consistent with a higher release point. 二缝线的出手点更高，下沉效果更佳 （可参考作者之前分析大Z的文章) A quick look at his stats shows the highest GB/FB rate of his career while maintaining a healthy strikeout rate and low walk rate. I would love to have a handy chart that shows me Beckett's pitch selection this year. I don't, but I would guess that the best GB/FB rate of his career correlates to him using his sharper and more ground ball friendly two-seamer more effectively. 滚球比增加（别再叫他全垒打王..话说之前还为了这事在MLB板上跟人笔战XD) K/BB值也进步， 我猜是因为他今年用更多角度更锐利的二缝线 Final Thoughts 结论 There's countless reasons for Beckett's strong start this year. Pitch selection and location are certainly a factor. However, we shouldn't understate the impact that improved mechanics can have on a pitcher. By keeping himself more "compact" (lower hands, leg closer to his center of mass, his body not leaning back), simplifying his delivery and slightly altering his arm slot, Beckett has been able to improve his command while not affecting his "stuff." Beckett今年的进步有很多理由 投球策略变好，还有投球动作更紧密，简化过程 都让他的stuff进步 I'd like to make one more very important point. As I pointed out at the beginning of the article, I don't believe that "being more deliberate" and "slowing himself down" have had any effect on his mechanics. As a matter of fact, I could probably make a better case that he's actually faster this year with his delivery. Tempo, in Beckett's case, is a non-issue since he appears to be very similar in that department this year. That said, if Josh Beckett thinks that he's being slower, and this mechanical cue helps him think that he's more in control, then I'd encourage him to continue with this thought process. For some reason, it reminds me of a quote by the great Yankee, George Costanza: "Remember Jerry. It's not a lie if YOU believe it." 最後还是要强调， 我不相信投球节奏变慢对投手是好的， 撒克斯队讲的话不想翻.. Sometimes what a pitcher thinks is happening is more important than what is actually happening. 这段不懂..投手想的比做的重要？ Good luck the rest of the way Josh. 希望他接下来也能表现良好 後感： 感觉是翻了篇废文，花了我一小时多还没得到什麽... 刚初看到这个标题还很高兴的想翻出来给大家看... 浪费大家时间了...抱歉 --
