Branch Rickey's set of outstanding hitters in baseball over the period 1920
to 1950 based on the sum of what Rickey defines as on-base- average and
extra-base-power (OBA + EBP).
我查了一些文章關於 OBA和EBP的文章
http://en.wikipedia.org/wiki/On-base_percentage
In baseball statistics, on-base percentage (OBP) (sometimes referred to as
on-base average [OBA], as the statistic is rarely presented as a true
percentage)
所以說OBA就是=OBP ?
關於 EBP的部份
http://answers.yahoo.com/question/index?qid=20110615003014AAZEioS
裡面有提到 EBP was a predecessor to slugging percentage.
還有一篇

節錄一小段
DETROIT - Derek Jeter's cold start continues to be a hot topic, but while his
.250 batting average remains the primary focus, his lack of extra-base power
should be even more troubling to the Yankees.
請問一下什麼是 extra-base-power (EBP)
這個是怎麼算出來的?
還有這兩者加起來代表的涵義是(OBA+EBP)?
有提供詳細數據的網站嗎?謝謝
