CLEVELAND -- MLB's Statcast logged 60 percent of Daniel Norris' pitches on Wednesday night as sliders.
He didn't throw that many.
But it wasn't necessarily a glitch in the algorithm.
In past years, his slider might be clocked at 88 or 89 mph, which looked good when paired with a mid-90s fastball.
But on Wednesday, Statcast couldn't tell whether those 88 mph pitches were fastballs or sliders. Norris said many of them were fastballs that were cutting. That movement, paired with Norris' dramatic dip in velocity, made them look like sliders to the pitch-tracking system.
