※ 引述《Sechslee (<ゝω・）绮罗星☆)》之铭言：
: 2010 Beyond the Box Score Catcher Defense Rankings
: http://ppt.cc/eWY4
: 作者统计2010年有蹲捕的球员 (共120名, 转队者分开计算)
: 根据 守备失误 Fielding Errors (FE)
: 传球失误 Throwing Errors (TE)
: 捕逸和允许暴投 Passed Balls and Wild Pitches allowed (PBWP)
: 阻杀 Caught Stealing (CS)
: 计算每位捕手守下的分数，和平均等级比较後做成排名。
: (计算公式在网页下方)
我发现Yadier Molina的Total 原网站有算错
应该是14.7的，写成14.6
帮补公式
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.
总之就是一个跟联盟平均比较而得的相对数据
难得出现一个参考价值不错的捕手衡量工具，可惜没有取名字的样子XD
另外，还有提到一个scouting report
我就不贴内容了，只附网址
