Dude... The very next sentence is: "Then again, Gibson has some basis for this, skill-wise. His four-seam fastball, which he threw 19.5% of the time in 2014, induced a popup in an incomparable* 15.8% of all balls in play." Followed by: "Gibson utilized his four-seamer entirely differently than he did any other pitch, and he uncoincidentally saw entirely different results from it. Sure, it didn't get him too many ground balls — 40.5% worm burners, only marginally better than average — but the weak contact he generated from avoiding the zone compensated for that. If he continues to execute in this manner, the infield fly balls shouldn't disappear."
