【松焦油後續】
Bauer前陣子在推特上嘴了聯盟裡松焦油的問題
他今天針對這個風波說明了一下
他說他沒有要針對太空人
但是他認為這是棒球場上日益增長的問題
他絕對沒有說太空人作弊
相反的，他覺得太空人的球員養成做的很棒
Bauer之前說過，根據他自己的研究
只要使用了松焦油，他的轉速可以提升三四百轉
在他美國時間這個禮拜一的先發之前
他今年的四縫線平均轉速是2294 RPM
但是這個禮拜一他在第一局投了9顆四縫線
這9顆的平均轉速是2597 RPM
難道他在驗證他的松焦油轉速論嗎？
賽後有人問他第一局是不是在球上加了什麼東西
Bauer的回答是"no comment"
文：Xavier，現代棒球近年越來越常聽到轉速（Spin Rate，SR）這兩個字，轉速和出手角度是衡量投球的重要指標，會影響到升力和阻力以及球的行進方向。 ... <看更多>

Spin Rate: The New Standard For MLB Pitchers
Shawn Ferris | Jun 05, 2015 1:54pm
Look out baseball fans. The new standard to measure your favorite pitchers is
coming.
球迷們看過來,衡量投手的新標準來摟
With each passing season, it seems like there's always something new. With
all the money thrown at the multi-billion dollar corporation that is Major
League Baseball, the good ol' fashioned eye test just doesn't work anymore
when it comes to evaluating players. Whoever utilizes the next level of
analytic data (supposedly) comes out on top, or at least you're going to have
a tough time winning without it.
每過一季都會有新東西出現.MLB身為每年數十億美元產值的行業,評估投手用傳統的眼睛
看已經不再好用.不論是誰能夠好好用新工具就能夠贏更多,至少沒有的話很難贏
Thanks Billy Beane. Moneyball has opened Pandora's Box.
謝謝豆爺,錢球帶來新的潘朵拉寶盒(???)
It sure as hell isn't as easy as simple as batting average or ERA anymore
either. Fangraphs.com has taken it to the next level, tracking every pitch,
swing, and catch since 2002, with data collected for pitch type, velocity on
those pitches, batted ball tendencies, and oh so much more.
不再像以前那樣簡單的用打擊率自責分率評估,Fangraphs從2002開始用下一世代的科技
去記錄每一球,每次揮擊,接球,球種 球速,揮擊機率...更多更多
It's enough to grab your favorite hoodie, curl up in the corner of your room,
and stare blankly at a wall.
這些已經夠讓你拿你的帽t在角落蜷身兩眼無身看著牆了
It can get to be a little much.
這有點太多了
But why stop there? Major League Baseball agrees with that statement, and
this summer you can have the newest pitching standard at your fingertips.
Because believe it or not, all 95 MPH fastballs aren't created equal, and
breaking balls? Forget it. They're like fingerprints.
但為什麼停在這,MLB發佈消息說在這夏天你可以用鍵盤查到新的投球數據,
不管你信不信,每一個95mph速球都不一樣,而變化球?更不用說了,他們像指紋一樣
Spin rate is here. Get use to hearing about it.
轉速來摟!以後要習慣聽這個了
Let's simplify what this means. Spin rate--by definition--is considered
aprimary indicator of swing and miss ability, the speed the ball is spinning
as it leaves the pitcher's hand in Revolutions Per Minute, or RPM.
簡單的說,轉速(從定義上來說)是評價揮空率的第一指標,球從投手離開的轉速
每分鐘轉多少圈,簡稱RPM
So is it as simple as...high spin rate = harder to hit? Well yes, that can
definitely be said about breaking balls at least. At his peak, Justin
Verlander's curveball had an RPM of 3,000, and spun 23% faster than the
average MLB pitcher, and the results certainly showed in his swing and miss
rate on the pitch, as well as his ERA and WHIP.
所以簡單來說,高轉速=很難打? 嗯..對,對於變化球來說至少這樣.在虎王的巔峰時,
他的曲球轉速高達3000,比MLB平均高23%,而這反應了他的揮空率還有ERA, WHIP
