以下是 Frankie Piliere 對 Javy 投球機制的分析 http://0rz.tw/SYFXA ==== The way he's delivering the ball, he's throwing against his front leg, rather than driving over the top of it and getting on top of the baseball. Again, Vazquez always has and more than likely always will collapse on his back leg and drift toward the plate. But, recently it's just gotten away from him. Because he's unable to drive over that front leg and get on top, he's forced to rotate around his torso and shoulders, creating more of a side-to-side effect than a downhill effect. What that turn of his shoulders does to the pitch after it leaves his hand is what's directly leading to all those mistake fastballs and rolling curveballs over the fat part of the plate. As his front side drifts toward the plate, his lead shoulder is going with it and opening up much too early. The impact of that is a nearly squared up upper body facing home plate, making it almost impossible for Vazquez to get the extension he needs to get the ball to the outside corner against righties, and the inside corner on lefties. With that front shoulder wide open, he's getting around his pitches rather than on top, causing the ball to repeatedly leak way back toward the middle of the plate. Not to mention, he's giving the hitters a very good look at the ball and his pitches are coming in on a flat plane. Pitchers need that good downward angle to stay out of the middle of the plate, and get the bite on the breaking ball and sinking fastball. By doing this, he's also robbing himself of a couple ticks on his fastball, for those out there wondering why his fastball has been more like 87-91 mph rather than 90-92 mph this season. As early as he is right now with his lower half, he's robbing himself of a great deal of leg drive, and when you are getting around the ball rather than on top, you are losing that raw velocity and downward action in favor of excessive arm-side run, which of course leads to mistakes over the plate. All of his pitches, particularly the curveball, are suffering from this mechanical issue. ==== Frankie Piliere 提到 Javy 的投球機制的改變，以及造成球速下降以及容易被打長打的原因。(詳細的機制就請看得懂得大大幫忙解說吧@"@) 文中也提到，即使知道原因要改也是不容易的事情 (It's a nagging mechanical issue , and despite being not so hard to identify it's very difficult to correct and keep in check on a consistent basis.) 希望跳過這次先發可以讓 Javy 改正回來...下次先發的對手老虎隊也不會比襪襪好打多少..... -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 220.143.158.106

欸.....我們的投教並不是沒在做事情的... 其他投手我不清楚，只拿 Boone Logan 為例子好了.. 以下是 Ken Rosenthal 的報導部份摘錄 http://0rz.tw/xizWt As if the Yankees need more help, club officials are excited about left-handed reliever Boone Logan, the second player they acquired in the Javier Vazquez trade. Logan, who throws 91-94 mph, is benefiting from a mechanical adjustment that pitching coach Dave Eiland suggested in spring training. Eiland asked Logan to lift his leg higher in his delivery and throw from more of a downhill plane, enabling his arm to get out front. Logan noticed an immediate difference — his four-seam fastball started moving in on left-handed hitters instead of tailing back over the plate. His changeup returned, and his slider gained late movement. Boone Logan 的圖片 http://riveraveblues.com/wp-content/uploads/2010/04/Logans-leg.jpg
