Both the pitcher and the catcher exert an equal impulse on the ball to change its momentum. The pitcher applies a force over a certain length of time to accelerate the ball and change its momentum....then the catcher reverses the change in momentum by exerting another force over a certain length of time.
However, the different between what the pitcher does and what the catcher does is the length of time the total impulse is delivered. The pitcher has a "windup" and "pitch" to accelerate the ball....which takes a comparatively much longer period of time than the split second the catcher stops the ball in.
The catcher must exert a much greater force over a shorter length of time to stop the ball compared to the pictures smaller force applied over a longer period of time.
At any given time, there is some force F acting on the ball, but over time as the force is applied, an overall impulse is applied on the ball to change its momentum. Force more of an instantaneous concept, compared to impulse which takes into account the time it takes to apply the force.

I'm gonna say the force is identical between pitcher and catcher, but the impulse is greater on the catcher because he catches it in a fraction of a second where the pitcher gets lots more time to hurl the ball.
But I really dont' know. Impulse force momentum are all somehow related. I got a gut feeling impulse and force are different but can't say how.

Assuming the ball doesn't change speed in flight, the forces should be equal, and I think the impulses should be also.
In reality, since the ball will accelerate in flight due to air resistance, the pitcher would exert the greater force.

I think the first answer is right so I'm going to give him a thumbs up but I think he made a typo... he probably meant to say decelerate (or maybe he meant accelerate in the opposite direction of movement)

I know you're looking for "the same", but what about centripetal force during the windup?

maybe I'm wrong but, i think it's the same for both.
