※ 引述《abc12812 ()》之銘言： : http://www.baseball-intellect.com/chien-ming-wang-pitching-mechanics/ 隨手翻一下 : A reader asked me what was up with Chien-Ming Wang, so I went to the tape. : I watched some video of Wang from way back in 2007 up to his most recent : start and I also happened to catch Steve Phillips and his breakdown of Wang’ : s mechanics on “Baseball Tonight”. 有讀者問我王怎麼了，所以我看了些錄影帶同時看了有關王的"Baseball Tonight." : One of the changes mentioned by Phillips was a change in posture, something I : noticed, but couldn’t confirm because of the difference in camera angles in : the video I watched. But the Phillips piece helped me confirm there had in : fact been a change in posture. He’s much more slumped over than he was in : the past, which you can see below. The 2007 version on the left (88 mph : fastball), while the 2009 version on the right (95 mph fastball): 第一個改變是姿勢，但攝影角度不同所以我也不能很確定但王在2009的姿勢的確比起以往往下傾蠻多的 : The next thing Phillips mentioned was Wang’s dragline. Now, Wang has never : had a consistent dragline. Most times there would be dragline, especially on : the fastball, but there would be times where Wang never had a pronounced : dragline. But it’s true that when Wang throws for a high velocity, there : usually is a more pronounced dragline. Compare the two clips below. Again, : the 2007 version is on the left and the 2009 version is on the right: 第二點就是王的dragline(很難翻譯請自行體會) 王現在的dragline一直沒固定住，有時候有，但大多時候都不明確但他球速比較快時，dragline通常也明確得多 : Let me explain the significance of the dragline and how it relates to : posture. The dragline is a result of efficient mechanics. A pitcher with poor : posture that lacks balance is at risk for having their back foot lift up : prematurely. An inefficient hip rotation can also lead the back foot to lift : early. A dragline is not always necessary for a pitcher to produce velocity : and many pitchers are very successful without a dragline, but for Wang, he : seems to be a pitcher where the dragline is an indicator of mechanical : efficiency and therefore is necessary for velocity 當你投球機制有效率時你的dragline也會比較好一個dragline不好的投手可能會有比較大的機率過早提起他的後腳差勁的臀部轉動也會讓後腳太早提起來未必每個投手都隨時需要保持dragline才能投得好但dragline對王似乎就是投球機制跟球速的指標 : The third thing Phillips mentioned was that Wang’s leg kick was lower in : 2009 than it had been in the past. The below clips are synchronized to : release with the 2007 version on the left and the 2009 version on the right. : In addition to Wang’s leg kick being higher in 2007, also take note of how : Wang’s knee in 2009 starts to drop before the point in which the 2007 version : ’s knee reaches its uppermost point: 第三件事情這個球季王的抬腿低了注意看王09年腿開始落下的時間提早了 07年是膝蓋抬到頂才落下的 : Wang’s tempo — meaning the number of frames from when the knee reaches its : uppermost point to the point of release — for both versions is 25 frames. So : if the 2007 version is covering more distance in the same amount of time, : that means his body is moving faster into release than the 2008 version. The : faster a player moves into release, the more velocity one generally has. : We also see changes in his arm action, but I think it’s because Wang’s body : is moving faster. If the body’s moving faster, so is the arm. It’s all : about efficiency and making sure all those moving parts are in-sync with one : another. It’s likely that Wang’s timing as it relates to his arm action has : been thrown off by the changes to his tempo and posture. 王的tempo-指的是從"腿抬到最高"到"球投出"這段時間的畫格數這兩個例子都是25格所以如果07年這25個畫格cover的時間比較長的話那表示他在07年身體動得比08年快(?應該是要說09年) 通常從開始動到投球的速度快也代表著球速會比較快我們也可以看到他手臂動作的改變我想這是因為他tempo跟姿勢改變而造成的不協調 : So my advice for Wang? First correct the posture problem by going back to a : more upright position. Second, he needs to increase the tempo of his delivery : and get his body moving at a faster rate, which should help correct the : timing problems he’s developed. If he fixes the first two issues, the : dragline should come back on its own because a dragline is a result of : efficient mechanics and not something a pitcher can control on his own. : I’m not saying anything groundbreaking here, but it’s extremely important : for Wang to get back to what he once was because the Yankees will be looking : at a long road to the playoffs in the vaunted AL East without him. 所以我建議王：第一修正回到過去比較直立的姿勢第二他必須增加他投球的tempo 讓身體動得快一點修正這兩個dragline應該就可以回來了我沒什麼新的東西要說但王能回來對洋基挺進季後賽是非常重要的畢竟是在這個靠杯強的美聯東區 -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 140.112.217.25
