有些是打者時代,有是投手時代等等,不同時代用ERA+參考不是比較快嗎


陳的我不想PO,這種資訊很好找,有興趣就自己去找
老王2006 ERA+ 125
老王2007 ERA+ 122
的確我認同王不是屬於ACE型,但上面有些人發言真的也太印象派了
把老王也說的太鳥了吧


Adjusted ERA+
Adjusted ERA+, often simply abbreviated to ERA+ or ERA plus, is a pitching statistic in baseball. It adjusts a pitcher's earned run average (ERA) according to the pitcher's ballpark (in case the ballpark favors batters or pitchers) and the ERA of the pitcher's league. Average ERA+ is set to be 100; a score above 100 indicates that the pitcher performed better than average, below 100 indicates worse than average.
For instance, if the average ERA in the league is 4.00, and the pitcher is pitching in a ballpark that favors hitters, and his ERA is 4.00, then his ERA+ will be over 100. Likewise, if the pitcher is pitching in a ballpark favoring pitchers, then the pitcher's ERA+ will be below 100.
As a result, ERA+ can be used to compare pitchers across different run environments. In the above example, the first pitcher may have performed better than the second pitcher, even though his ERA is higher. ERA+ can be used to account for this misleading impression.

另外補一張1993~2014趨勢圖,看的懂得人就應該看的懂

League Year-By-Year Pitching--Averages

王建民 在當年 的確可算的上 NYY的 1號先發
但稱為ACE級 仍稍不夠格
來看一下
2006年的 WHIP: 1.31 MLB 先發投手中第36名 ERA3.63 排行第16
2007年的 WHIP: 1.29 MLB 先發投手中第32名 ERA3.70 排行第25
接下來 殷帝
2014年 WHIP: 1.23 MLB 先發投手中第39名 ERA3.54 排行第44
不可否認 當年是打者強大的年代(吃藥吃很大?) 現在則是投手的光輝年代
但我認為 其實 當年的大樹跟去年的殷帝 其實是差不多水平的好先發
可以稱為 優良的#2 或 後段班的#1
要跟年薪2000萬+的 ACE級比 還少了那麼一點
