: 如何定義一個野手位置的防守範圍是內是外?

: 應該是指防守時移動的距離?

細節應該買一下John Dewan的The Fielding Bible, 美金19.95元

這個部落格到是有人看過了, 做了點評論
2) The zones. This is more likely the culprit. According to this grid used
for STATS, there are 8 x 22 or 176 places where a ball can land. In The
Fielding Bible (pg 9) there are about 260, though there is no map showing
exactly how they are structured. I would lean towards trusting the system
with the more detailed data, but I really have no idea which is closer to the
truth.

STATS有176格去計算球的落點, John Dewan的書中則提到他用了
260格去計算, 只是書上沒有如STATS把圖列出來, 作者則相信他
應該是真的有經過詳細的安排過。
唉! 這門統計學我們的職棒還要多久才追的上。
