※ 引述《unidon (uni~uni~uni~daisuki~!!)》之銘言:
http://www.observer.com/2007/chien-ming-wang-occasional-ace?page=0%2C1
Wang was victimized by a .366 BABIP in August entering today’s game, and had
a 5.46 ERA for the month as a result. His career BABIP mark of .291 has
yielded a career ERA of 3.83.
王建民八月為 .366 的 BABIP 所苦,該月 ERA 為 5.46。
而他的生涯 BABIP 只有 .291, ERA 為 3.83。
The problem is that BABIP is not a repeatable skill. Pitchers as skilled as
Pedro Martinez in his prime have seen BABIP go from .325 in 1999 to .217 in
2000. Pedro, however, took the spinning of the roulette wheel out of his
results often, striking out 313 in 213 innings in 1999, while walking just
37. He was able to minimize the damage luck could deal him.
問題在於 BABIP 不被視為是投手所能控制。
即使像是 Pedro Martinez 這般有經驗的投手,他的 BABIP 也有過 1999 年 .325,
到 2000 年 .217 的波動。然而 Pedro 靠著他的球威 (K/9 被視為是投手能力)
在 1999 年 213 局的投球中拿下 313 K,只送出 37 BB ,使得他被壞運氣的影響
被降到最低。
Contrast that with recent Yankee Aaron Small, whose strikeout rate of 4.25
over two seasons in New York bests Wang’s career mark. Small held batters to
a .277 BABIP in his magical 2005 season, overcoming a strikeout rate of just
4.38 to post a 10-0 record and 3.20 ERA. In 2006, with a strikeout rate of
four per nine (but a BABIP that jumped to .388), Small posted an 8.46 ERA.
Aaron Small 在洋基的表現則是巨大的對比。
他在洋基兩季的 K/9 是 4.25,比王建民的生涯三振率高。
Small 在輝煌的 2005 球季展現出 .277 的 BABIP,所以即使 K/9 只有 4.38,也能投
出 10-0 的成績,以及 3.20 的 ERA。
然而在 2006 年,他的 K/9 落到 4,而對戰 BABIP 變成 .388,ERA 則上升至 8.46。
This is not to say that Wang’s performance will fluctuate as much as Small’
s did (for one thing, Wang’s walk rate remains steady, while Small’s did
not). But pitchers on the low end of the strikeout spectrum are extremely
vulnerable to the variables of baseball luck.
這並不代表王建民的表現會如同 Small 一樣崩盤 (例如王的 BB/9 相當穩定,而
Small 並非如此) ,然而低三振率的投手比較容易受到運氣的影響。
Wang also may not be so lucky with the home run ball, despite his ground ball
tendencies. He’s allowed seven long balls in his 166 1/3 innings this
season. But Seattle’s Felix Hernandez, whose groundball/fly ball ratio is
slightly better than Wang’s, has given up 17 homers in 150 innings. Even
Cleveland’s Fausto Carmona, whose 3.33 ground balls for each fly ball is
significantly better than Wang’s 2.62, has allowed 14 long balls in 173 2/3
innings.
即使 G/F 比相當極端,王建民在不被擊出全壘打方面,恐怕運氣成份也相當重。
在他本季 166.1 局的投球中只被擊出七隻。
以 Seattle 的 Felix Hernandez 為例,他的 G/F 比王建民略高,但他在 150 局
的投球中也被打了 17 隻全壘打。即使是 Cleveland 的 Fausto Carmona,G/F 是
3.33 遠高於王建民的 2.62,也是在 173.2 局的投球中被轟 14 發。
Home run rate also fluctuates from year to year, regardless of the pitcher.
Brandon Webb, who throws a sinker as his main pitch as well, allowed 21 home
runs in 2005, 10 this year. Bruce Sutter, whose sinking action on his pitches
put him in the Hall of Fame, allowed 10 home runs in 101 1/3 innings in 1978,
then just 3 in 99 innings in 1979. And Sutter struck out well over a better
per inning in both seasons, meaning he had far fewer balls in play that could
leave the park than Wang does.
HR/9 不被視為是投手能力,因此可能會有大幅變動。
同樣以伸卡球為主要武器的 Brandon Webb 在 2005 年被打 21 發全壘打,而今年
只有 10 發;Bruce Sutter 靠伸卡球進了名人堂,他在 1978 年 101.1 局被打 10
發,而 1979 年 99 局 3 發。Sutter 這兩個球季的 K/9 相當不錯,使得他被擊出
的球遠比王建民少。
So the next time Ching-Mien Wang pitches, bring your rabbit’s foot to Yankee
Stadium. Rub Freddy Sez’s four-leaf clover for luck. And if you don’t see
batters swinging and missing much, hope the energetic Yankee hitters can come
to the rescue.
所以當你下次看到王建民主投時,最好帶著兔腳或幸運草。
如果他的三振率還是一樣低,恐怕只能靠打線幫忙囉。

我覺得這篇是傳統數據頭的看法,只是拿舉例代替數字統計,使大眾容易了解。
所謂的投手能力,指的是某些統計數據,在同一個投手身上傾向不會大幅改變。
常見的數值包含有 K/9, K/BB, G/F/LD% 等等等。
如果說有個投手這些數據並不很漂亮,但勝敗場數 (最容易受到污染的數據)
或 ERA (其實也滿髒的) 卻大殺四方時,數據頭會試圖找出原因。
當一個投手可能因為一些 "非能力" 的數值,使得帳面上的成績很好看時,
運氣可能佔了大部份的因素。
而 BABIP 和 HR/9 確實不被視為是投手能力。

反過來思考,為什麼一個低 K/9 的投手,能夠連續兩年擠進勝投排行榜呢 ?
1. 他有很好的 RS (Run Support)。別懷疑,這相當重要。
拿某位號稱熱身兩百球的東瀛投手的數據來看看就知道了。
W L ERA G GS CG SHO SV SVO IP H R ER HR BB SO
王建民 16 6 3.79 25 25 1 0 0 0 166.1 167 71 70 7 45 86
某 M 13 11 3.88 27 27 1 0 0 0 176.1 159 76 76 20 66 174
請不要說某 M 是因為被打 20 隻全壘打,失分比較多才拿到 11 敗的。
ERA 能充份駁斥這種論調。
2. 不錯的控球
IP SO BB K/9 BB/9 K/BB
2005 116.1 47 32 3.636 2.476 1.469
2006 218.0 76 52 3.138 2.147 1.462
2007 166.1 86 45 4.653 2.435 1.911
這會表現在 K/BB 和 BB/9 上頭。
王建民本季 BB/9 略升,不過因為 K/9 K/BB 都增加,代表王建民攻擊好球帶
邊緣的能力上升,而且是有效的攻擊 (K/BB 上升)。
3. DP ? G/F/LD% ?
肯定有某些數據,是對比賽結果有重要影響,但目前未被發掘出來的。
點點點~
