[問題] GameDay 中的 NF 是什麼?
在 GameDay 裡面有一個小視窗顯示投手的 pitch-by-pitch,
比如說
Result MPH Pitch NF
Ball 80 Curveball 40
Swinging Strike 94 Fastball 54
之類的,
我想請問 NF 代表什麼呢?

然後我找到了:
What is the Nasty Factor?
The Nasty Factor evaluates several properties of each pitch, and rates the
"nastiness" of the pitch on a scale from 0-100, based in part on the success
or failure of opposing hitters against previous similar pitches. The Nasty
Facto incorporates several different factors for each pitch, including:
Velocity —
The greater the pitch's velocity — as compared to that pitcher's and the
league's range of speed for that pitch type — the greater the nastiness;
Sequence —
The more the pitcher mixes up his pitches, the greater the nastiness
… and certain pitch sequences are nastier than others, too;
Location —
The closer to the edges of the strike zone is, the greater the nastiness,
while pitches closer to the middle of the plate, and farthe outside the the
strike zone, decrease in nastiness;
Movement —
The more movement the pitcher applies to the pitch — as compared to that
pitcher's and the league's range of movement for that pitch type — the
greater the nastiness.
The Nasty Factor also adjusts for how often the pitcher has faced the current
batter during the game, as well as how often he has used the same pitch type
against the same batter in the current at-bat and previously in the game.
