Spencer Schwellenbach refined his slider location to righties. The swinging-strike rate has soared:


This is really cool. It's been discussed before, but he was throwing pitches too far in the zone when he was ahead in the count – basically throwing too many strikes at first. He's corrected that now and the results speak for themself.

  1. It’s really incredible seeing him develop in real time like this. That improvement is insane not only in how much better it is, but also in how fast.

  2. It’s insane how quickly he has improved and adapted to MLB talent. Will be curious to see how he adapts once the league starts better adapting to him, but sky’s the limit for this dude!
