Anderson seems to have this unique mix of fastball/change where they both come out at the same armslot and trajectory, except the change goes down and is 8 mph slower. If he can K Soto on a change right down the middle, I feel like it has to be that it comes out EXACTLY like the fastball, and the hitters have no idea which is which until it's too late.
Yeah. This is the idea of tunneling. It's been speculated that Anderson is likely really good at this which makes his stuff play up. I do wonder if the straight over the top delivery helps with it.
