He threw that thing 80+ mph. There’s only two knucklers in the bigs currently, RA Dickey for the Braves and Steven Wright for the Red Sox. At least to my understanding. I will always try to watch a knuckleball game. You never know what you will see.

A Phil Neikro knuckler was very slow, think in the 60s- 70s mph range.
Velocity comes from the stretch and legs, and with a big part the wrist snap.
Plus long fingers that can put that edge on the throw.
I am amazed that a human could throw a knuckler at that velocity.
Hell, I thought 80 mph was fast without any movement
For reference just go to a batting cage and try to hit the ball.
No wonder Dickey is unhittable.
