在美國這個叫做pitch tunneling
推薦這個youtube channel 雖然訂閱數少
但是基本上把現今職業棒球與大學棒球 數據分析的東西講得相當有條理
https://www.youtube.com/watch?v=IuyHjl6XwOA
他的影片基本上把你想知道的都講了一遍 對於美國職棒與大學棒球實務經驗有興趣
推薦看一下
youtuber本身待過金鶯隊系統 現在是NCAA D1 Penn state棒球隊 負責球員培育
還蠻有料的
正題開始
投手球投出 約0.4秒通過本壘板上方 人約需要0.1秒來反應
決定揮棒到棒子通過本壘板上方時間是0.18秒
所以大概只有(0.4-0.1)-0.18=0.12秒來判斷球種
這邊的共軌效應 or pitch tunneling就是直球跟變化球 接連兩顆軌跡都很相近
在上面說的0.12區間無法判斷球種 導致開始揮棒之後 軌跡才產生變化
以時間軸來看
0.0 0.1 0.22 0.4
|________________|____________________|_____________________________|
投手球投出 打者反應 打者決定是否揮棒 揮棒與否
那來看個例子吧 假設今天有個打者與投手對決如下
0.0 0.1 0.22 0.4
打者 "這顆是直球 尻支大的" "沒打好界外"
|________________|____________________|_____________________________|
投手 "投直球"
下一球來了
0.0 0.1 0.22 0.4
打者 "阿幹這顆球軌跡一模一樣 不能miss" "揮棒落空"
|________________|____________________|_____________________________|
投手 "投滑球" "球開始往外滑"
這個就是好的pitch tunneling
pitch tunneling建立在兩點
1. 優異的控球 有辦法連續兩顆 把直球跟變化球控制在相近的軌跡上
2. 一定程度以上的球速
因為物理的關係 不同轉軸跟不同轉速的軌跡注定要不同
單單有優異的控球 但是球速慢沒用 球速慢 打者的反應時間就多
假設一樣能共軌到上面時間軸0.22秒 但是球速慢10%的 就會變成
0.0 0.1 0.22 0.26 0.44
"阿幹是滑球"
|________________|____________________|_________|____________________|
"球開始變化"
反之 如果是球速快10%的
0.0 0.1 0.18 0.22 0.36
"直球 得揮棒"
|________________|____________________|_________|____________________|
"球開始變化"
兩者的效果顯而易見
單純只有球速快 控球不好也沒用
Jordan Hicks 直球系球速是MLB最快的之一 但是只有聯盟平均的K% 約25%
一方面在於直球系轉速不高 Whiff低 另一方面也是控球很差
另一個球速一樣快的Aroldis Chapman K% 40% 就是聯盟佼佼者
變化球去追求超高轉速不一定是最佳解 與其丟一顆3000轉的曲球 但是早早就被看破
不如丟一顆2400轉的曲球 利用pitch tunneling來壓縮打者反應
這也是為什麼全盛期的Kershaw變化球轉速都是大聯盟平均左右 卻有不錯的whiff
看看光芒的Tyler Glasnow 直球100mph 曲球3000轉 還有pitch tunneling
所以去年他的曲球Whiff是53%
https://youtu.be/ogXKk98UxGk?t=555
簡單的說 共軌效應=pitch tunneling 需要1.良好的控球 2. 一定程度的球速
更棒的是 這個youtuber還教你現在美國主流pitch design的實務
https://www.youtube.com/watch?v=SpultqwZgOg
不過現在中職也都採取這套了 怎麼練出pitch tunneling就是另個課題
※ 引述《zaxs ()》之銘言:
: 剖析徐若熙驚人投球 餅總:共軌時間拉長、非常難練
: 記者歐建智/台南報導
: 味全龍投手徐若熙17日先發3.2局11個出局都是三振的破紀錄表現,統一獅總教練林岳平
: 說:「太驚人了。」
: 他分析徐若熙優異投球主因是直球與變化球的「共軌時間」拉長,這是每位投手都嚮往
: 練到的水準。
: 徐若熙17日先發3.2局,面對15人次打者,用62球達到設定球數退場,除了被打3支安打、
: 1次觸身球之外,11個出局都是三振是中職史上第一人,刷新新人初登板紀錄,成為大家
: 關注及討論的焦點。
: 林岳平在17日比賽結束後回家,也看了徐若熙的11K投球,他分析徐若熙的投球優異點是
: 「共軌時間拉長」,直球跟變化球出手及飛行路徑幾乎相同,到最後才產生變化。
: 他分析,徐若熙的投球共軌時間拉長之後,打者難以在最後判斷直球或變化球,這是每位
: 投手都嚮往練到的水準,
: 「這是非常難練的技術。」林岳平表示,徐若熙的球快又準,逼打者一定要出手,好球率
: 很高,打者一直出手、一直在揮空,自然三振多。
