Many of my teammates ask why I wear a cup, and that my glove should protect the jewels lol... Even our Senior SS that is definetely going at least to the minors says that I should just get used to fielding without one because you get better range of motion....
I've tried fielding without a cup and I definitely feel the more range of motion but I also feel my body jumping up on that last hop resulting in some balls bobbled or not fielded with my glove at all....
So, should I practice staying down on the ball without a cup, or keep it and forget about the range of motion...
