Here's what we actually witnessed:
FA at 94.7, which is above average. Somehow he got 9.9" of rise...which is close to Grade 80. His 3.0" of arm-side run is below average, but who cares, this is a plus rising FA. AJSS somehow turns mediocre spin into massive rise on a relatively straight FA. The same metric has Strider at 10.1" of rise, and AJSS is right there with him, albeit a few ticks less in velocity. This FA is what what we would see when Strider backs off a bit if he could keep his rising action at lower velocity.
SL at 85.1, which is average velocity. Glove-side break of 2.5" is average horizontally, and 2.0" of "rise" is average vertically. What I saw was a kid unable to finish his breaking ball, and left it up and all over the place, but if he executes this is an average or better pitch.
CU at 77.9, which again, is right around average velocity. Glove-side break of 4.8" is right around average, and 8.5" of sink is like Grade 70. This is a downer curve that's a legit plus or better out pitch.
So, I don't really know what to say. It's almost like someone took a MLB-quality raw arm, stuck him in a Statcast performance lab for 6 months to optimize his spin efficiency, and then unleashed him on minor league baseball. The data I just posted does not match the eye test, and now I have to re-watch the condensed version of this game to see what I missed. If that is his true arsenal he absolutely should be starting the next time his rotation spot opens, and we get to witness someone "learn how to pitch" who actually has a chance to be an impact SP. He is now the most fascinating player on the roster to me.
