[閒聊] BABIP投手

[charliee (Double E)]

Batting Average on Balls in Play (BABIP)

is the batting average against a pitcher, removing at-bats that go for HRs or
strikeouts. The normal BABIP or Hit Rate is 30%, meaning for every 10 balls
that have a chance to get fielded, three will find a hole and count as a hit.

Unlucky pitchers with have a BABIP above 30% likely resulting in a high ERA
and WHIP. Since their BABIP should regress back toward the mean of 30% these
pitchers are typically undervalued and good buy low candidates to add to your
team.

Cole Hamels, Derek Lowe and Ricky Nolasco are all starting pitchers that had
high Hit Rates last season.

BABIP:投手所投出的球，被擊進場內形成安打的機率(扣掉HR及K)。
      一個投手正常的BABIP是30%左右，代表每被擊出的十顆球當中，正常說來應該有
      三顆會找到洞鑽出去，這取決於後方的防守者，跟投手本身的投球能力較無直接
      關係。

      因此正常來說，投手的BABIP值最終都會接近30%左右這個數字，而09年當中有些
      投手因為過高的BABIP導致過高的ERA和WHIP就變成我們今年可以逢低買進的好投
      資。例如Cole Hamels,Derek Lowe,Ricky Nolasco等都是這類型的代表人物。


PS:請問除了這三位之外，還有誰啊?一個一個查好累@@
