※ 引述《WillWaiting ()》之銘言： : [quote] : ... I believe, and I have nothing but intuition to back this up, that : people who throw sliders lose their velocity more quickly than people : who don't. As they get older, and their fastball slows down, they tend : to rely more on the slider. The slider takes away from their velocity. : And before too long, their velocity--and the sharp slider along with : it--is gone. Instead of following the natural way to put force on the : ball, they try to create additional rotation by using their wrist. I've : seen this happen many times. : (Excerpted from "Nolan Ryan's Pitcher's Bible," at 172.) (前略)我相信, 並且可以很直覺地證實這個說法, 就是一旦一位投手開始投滑球, 他會比那些不投滑球的投手更快喪失球速. 當他們年紀漸長, 速球球速開始下滑, 更會倚重滑球. 滑球使他們的速球不再. 不用多久, 滑球會因為球速下降的關係失去球威. 他們開始藉著手腕的施力加強球的旋轉, 而不是像一般傳統的模式來投球. 我看過這樣的事情好多次了. (節錄自諾蘭萊恩的投手聖經, 一百七十二頁) : Foreword: The Vanishing Fastball (by Eugene Coleman) : Why, when pitching is so important, is there a shortage of power pitchers? : Velocity has decreased in baseball, to some extent, because young pitchers : don't throw enough fastballs, pitches per workout, or pitches per week. Some : professional scouts believe the problem begins in Little League. Young : players realize that it's easier to trick hitters than to throw a fastball : by them. The end result is a growing number of youngsters with good breaking : balls and below-average velocity. 前言: 消失的快速球 (By Eugene Coleman) 為什麼, 在投手是如此重要的狀況之下, 強力投手會有短缺的情形呢? 大環境來來說, 投手的球速在呈現下滑的景象, 因為年輕投手們在每一次練習,每一週投的快速球不夠多. 有些職業球探認為這個問題從少棒層級就開始產生. 年輕球員覺得用變化球欺騙打者比使用速球來的簡單. 結果就是越來越多年輕球員投的一手好變化球但是速球卻完全不及格. : The trend for high school and college pitchers is similar: College : pithcers today often throw 50 percent off-speed pitches, and the percentage : is even higher in high school. I've charted several successful high school : teams whose pitchers threw 60-65 percent off-speed pitchers. : Many people in professional baseball point to aluminum bats as the source : for changes in basic pitching patterns. The inside fastball, which almost : always jams hitters using wooden bats, loses its effectiveness against an : aluminum bat. Instead of throwing inside, then, pitchers spot their fastball : and use their breaking ball as their out pitch. These young pitchers : basically discard the fastball and do little to develop the strength and : durability of their arms. ... : "Nolan Ryan's Pitcher's Bible," at 9. 同樣的, 在高中大學球員也是類似: 現在的大學投手投球內容中大概有五成是變速球, 這個比率在高中甚至更高. 我觀察到幾隊成績很不錯的高中球隊陣中的投手使用變速球的比率是百分之六十到六十五. 許多職業棒球人指出使用鋁棒是改變投手習性的原因. 內角快速球幾乎總是使用木棒打者的罩門, 在面對鋁棒時失去了作用. 投手們因此不攻內角, 轉而封印自己的快速球, 轉向使用變化球當作是最後武器. 基本上這些年輕投手們放棄了快速球, 同時也放棄了增進肌肉強度與手臂的耐力, 這些速球投手所必須的訓練. -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 61.216.100.4
