用這種方式假定的盲點是你預設投手一定以投進edge為目標，但實際上不是。

直接用原po給的樣本查詢

Clayton Kershaw的Pitch Arsenal，曲球跟滑球都被大量拿來拐打者出棒。
Meatball 10.2% edge 41.3%
但是他長年BB%幾乎維持在Top5%。

Julio Teheran 47 %edge. 6.5 %Meatball
看起來不錯，但是他的Changeup投在edge還是被挨打很慘。

曲球、滑球或指叉球這類三振球，投到Edge時反而容易被打者破壞掉，解決不了打者。

投手們反而會刻意投到waste區域。那樣是否該稱為控球不好？

感覺可以用貝氏機率算一波 不過感覺要定義什麼是控球

理論上控球好是投手能不能準確投到他要的位置，通常是捕手手
套一開始擺的位置，但是目前Statcast沒有這種數據。所以目前
控球能力這個東西還沒辦法直觀量化

幫定義：Control指的是投進"好球帶"的能力
Command指的是把球投到自己想要位置的能力

Command的能力到目前仍然很難被量化來評估

就是說Edge%可能跟投球策略比較有關係

目前找到比較常用的指標是called strike probability

推正確解釋數據，不過edge%的確能更客觀的說明控球

一般來說 評價投手的球威 要比評價控球容易得多 可以從球速、揮空率、擊球品質下手 而評價投手的控球能力 粗淺的會直接看BB9 誠然 BB9 很高的投手 絕大多數有控球的問題 但是BB9低的就代表控球好嗎? 舉個例 綽號12M的Carlos Silva 2005年做到了投188IP 只有 ...
