Re: [情報] Graph of the Day: Wang's Spin Movement at Home
※ 引述《abc12812 ()》之銘言：
: http://www.beyondtheboxscore.com/2009/5/30/893513/graph-of-the-day-wangs-spin
: If you're saying Chien-Ming Wang's sinker has lost many inches of movement,
: you'll also have to say he used a screwball in 2008. Or you can just say
: that Yankee Stadium was wrong in 2007, adjusted too much for 2008, and again
: at the new park in 2009. Based on the slider movement, it's still off.
如果你認為王建民的沈球跑動幅度少了好幾吋，你也必須承認他在08球季用了一顆
『螺旋球』。或者可以這麼說，洋基球場在07球季怪怪的，在08年修正了太多，09
年在新球場也是。而從滑球的軌跡來看，似乎沒什麼差別。
: That makes it hard to tell what's changed with Wang without adjusting the
: base data. That includes the release points, the initial acceleration and
: velocity values.
而這（沈球變動大、滑球沒差）讓我們在沒有考慮包括了放球點、啟動加速及速度這類
基礎資料下，要去搞清楚王建民到底哪裡改變，變成一件困難的事情。

: 2009.
隨便翻一下，不過似乎沒啥內容＝ ＝
