好奇問一下：

MLB Gameday上對於投手投的每一球秀出的三個數據

SPD=Speed這個我知道

但
BRK和PFX各是什麼意思呢？（單位都是英吋，不曉得代表什麼）

引用:

BRK is the amount of inches on the break of the pitch

這釋什麼解釋 ???

引用:

The "Pitch-f/x" value is currently defined as the measurement of the distance between the location of the actual pitch thrown over the plate, and the calculated location of a ball thrown by the pitcher in the same way, with no spin

這片文章蠻有趣的
