: 2010 Beyond the Box Score Catcher Defense Rankings
: http://ppt.cc/eWY4
: 作者統計2010年有蹲捕的球員 (共120名, 轉隊者分開計算)
: 根據 守備失誤 Fielding Errors (FE)
: 傳球失誤 Throwing Errors (TE)
: 捕逸和允許暴投 Passed Balls and Wild Pitches allowed (PBWP)
: 阻殺 Caught Stealing (CS)
: 計算每位捕手守下的分數，和平均等級比較後做成排名。
: (計算公式在網頁下方)
我發現Yadier Molina的Total 原網站有算錯
應該是14.7的，寫成14.6
幫補公式
Stolen Bases/Caught Stealing:
A) figure out the league rate for caught stealing
B) separate the catcher caught stealings from pitcher pickoffs
C) total the CSctch +SB to get total stolen base attempts (SBA) and then to
total CSctch/total SBA for the lgCS rate
D) use the weight of .63 runs for each caught stealing, which represents the
avrage linear weight of the caught stealing (.44 runs) plus the weight of
the stolen base not achieved (.19 runs).
Formula for runs above/below average:
(CS - (lgCSrate) * SBA) * 0.63.
Wild pitches/passed balls:
The league rate = (WPlg + PBlg)/lgPA.
The linear
weight for each passed ball/wild pitch is 0.28 runs.
The formula for each
player is
((WP + PB) - (lgWPPBrate * PA)) * -0.28.
Wild pitches/passed balls:
The league rate = (WPlg + PBlg)/lgPA.
The linear
weight for each passed ball/wild pitch is 0.28 runs.
The formula for each
player is
((WP + PB) - (lgWPPBrate * PA)) * -0.28.
Errors:
There are two types of errors, throwing errors and fielding errors
.There are separate linear weights for throwing errors (-0.48) and fielding
errors (-0.75).
Throwing errors:
(TE - (lgTErate * PA)) * -0.48.
Fielding errors:
(FE - (lgFErate * PA)) * -0.75.
總之就是一個跟聯盟平均比較而得的相對數據
難得出現一個參考價值不錯的捕手衡量工具，可惜沒有取名字的樣子XD
另外，還有提到一個scouting report
我就不貼內容了，只附網址
