I was totally puzzled by the "NF" number on the mlb.com gameday pitch results. I had to search a bit to find what it meant...and it seems like lots of others were equally puzzled. It stands for "Nasty Factor." Why does mlb.com have this? It seems ridiculous. Baseball's a stat driven game, the addition of a subjective ranking of "nasty" pitches seems silly and needless.
