Larry Rothschild’s effect on pitchers
By Mike Axisa

When the Yankees hired Larry Rothschild away from the Cubs to be their new
pitching coach yesterday, Ben noted that his staffs tend to boast high
strikeout rates. Earlier this summer a poster on the FanGraphs Community blog
looked at exactly that, and found out that pitchers did in fact improve their
strikeout rates with Rothschild, close to 2.5% as a group. But what about
walks? Another Cubs Blog tackled that a few days later and found that yep,
pitchers improved their unintentional walk rate with Rothschild as well. More
strikeouts and fewer walks is a great recipe for success.

The Yanks as a group struck out 0.62 fewer batters and walked 0.19 more (per
nine innings pitched) in 2010 than in 2009, with CC Sabathia‘s rates taking
a hit in particular. With any luck, Rothschild will help get the staff back
into strikeout mode, which would be a tremendous help.

推 meier0112   :可以期待CC and AJ 重回08年的k功嗎XD
推 Zamned      :K功會提升 但是BB會增加
→ Zamned      :小熊投手很會投BB的
→ Zamned      :在Rothschild帶領下小熊有三年團隊保送數倒數第一
→ unicotexalex:no 你看錯了 他這邊說的是K率上升BB下降
推 Zamned      :但是事實是從他接手以來小熊的BB都不好看
→ unicotexalex:http://ppt.cc/6Ra,  可以參考這篇
台泥怪怪的 換一個

→ Zamned      :2002年開始 14 16 9 13 16 13 7 11 16名
→ unicotexalex:他是說會進步 不是看整個聯盟排名
→ Zamned      :文章看不到啊
→ Zamned      :被他帶起來的經典案例是Matt Clement和Ryan Dempster
→ Zamned      :也就是說 小熊是國聯最愛送人上壘包的球隊
推 Zamned      :那個名單裡有好幾個 10/21 BB%是往上跳的
→ Zamned      :這還沒加上農場中的超級BB戰士Samardzija
→ Zamned      :當然Rothschild是個好教練 在瑞格里滿偏打者的球場
→ Zamned      :貸出的成衣是相當好的 但是我覺得他調教保送方面
→ Zamned      :看不出什麼成果 一些新秀被他整理得不錯拿出去騙人
恩..他這邊取的樣本是02年他上任以來小熊簽約或交易來的投手，就是從外面弄來的。
然後根據 Sabremetric Library, K/PA becomes reliable after 150 batters
faced (BB/PA becomes reliable at 550 PA)這兩條再把沒達到標準的去掉，
最後再扣掉 Greg Maddux (Greg Maddux makes up such a large portion of the before
Rothschild group and Maddux's control wasn't as spectacular as we remember
early in his career)，剩下的投手K/BF從18.18%上升為20.35%，BB/BF從
9.55%下降成8.22%。參考看看，畢竟指的不是全部的投手@@

→ Zamned      :出去之後原形畢露 留在家裡的也是要壞不壞的
→ Zamned      :最照顧新人方面滿囧的 不過這也跟前幾年農場很爛有
→ Zamned      :關聯啦 XD
