[討論] 投手和防守的BABIP
http://www.hardballtimes.com/main/article/adjusting-defense-efficiency-by-the-quality-of-pitching/
以前說防守方的BABIP完全是運氣
近年的研究則認為還是有可以控制的部分
不過這篇文章實在太長..還有引用之前也很長的文章..
貼一些簡單明瞭的部分:
A) 較會三振的投手BABIP較低
B) 製造滾地球的投手BABIP較高
C) 愈不丟保送的投手BABIP較低
BABIP的成分:
A) 投手佔12%
B) 防守佔13%
C) 運氣佔75%
球隊的防守效率可歸咎為:
A) 48%的防守能力
B) 40%的運氣
C) 12%的投手能力
所以有的時候看起來防守很可靠，是因為投手自己就很強的關係
