Re: [討論] 守備範圍的依據?
※ 引述《FBLZA (我還是很喜歡妳)》之銘言：
: 請問一下
: 常看到酸隊長守的小
: 那守備範圍是怎樣看出來的?
: 還有之前有大大po過數據 每年多守幾分 多掉幾分
: 那是怎樣算出來的?

PMR : Explanation: Last year, I worked on a way of measuring range which I
called a Probabilistic Model of Range (see the defense archives). I was
basically repeating work done by Mitchel Lichtman which he named the Ultimate
Zone Rating (UZR). Since Mitchel's work was more mature than mine, and since
I had to write new software because the source of my data changed, I did not
puruse these ranking for the 2004 season. However, I just learned that
Mr. Lichtman is working for the Cardinals (congratulations, Mike!) and won't
be publishing his results anymore. There's a niche to fill, so here it goes.
I calculate the probability of a ball being turned into an out based on six
parameters:
1. Direction of hit (a vector).
2. The type of hit (Fly, ground, line drive, bunt).
3. How hard the ball was hit (slow, medium, hard).
4. The park.
5. The handedness of the pitcher.
6. The handedness of the batter.
UZR : 請自行上insidethebook查詢，我一時間找不到連結
: 一些小意見
: 判斷準確
: 守備範圍
: 守備確實 應該都很重要吧?
: 判斷準確有2種 判斷落點 還有接到球之後的處理 (ex. 要tag還是要傳1壘 等等)
Jeter最強的地方就在這裡: 球感很好
也因此給人一種防守厲害的錯覺
: 守備範圍 這大概是最難說的吧..
: 守備確實 就是守備率摟@@
這部份Jeter以前不好，現在還不差
