When a fielder stops a fast moving ball suddenly, change in momentum is brought about in a very short time, and hence a large force acts on the fielder's hand. Thus, his hand may get hurt. But, when the fielder stops the ball by gradually pulling his hand back, then the same change in momentum is brought about in a longer period of time and as a result,the ball will exert lesser force on the hands of the fielder and the fielder will not get hurt.
