Pineda will begin to stretch out bullpen sessions, throw changeups

I get why breaking balls are a much bigger deal than fastballs in terms of injury rehab. Breaking pitches put torque on the arm, which is more stressful. But it seems to me that throwing changeups should be pretty benign compared to fastballs. After the idea is to throw a change with the same arm motion as a fastball and simply change the grip. I throw accidental changeups all the time when I get a poor grip on the ball (as a position player).

I guess I’m saying that mixing in a few changeups doesn’t seem like that big of a step. I’ll be a lot more excited when i hear he’s throwing sliders.
