I bet bat rolling is big in men's softball leagues. In the geezer league, I've seen some old farts who can't even make it to first base hit tape measure shots. I've only heard of bat rolling within the past year so it got me thinking where some of these teams get their power from. Hitting with a composite is dangerous enough. Last year, I hit a shot to SS that put him in the hospital with a busted up nose (it was ugly)and I only used a DeMarini single wall bat and it wasn't even a composite. Also last year, playing 1B, I took a bad hop off the wrist and the ball deflected off my wrist and continued on to the RF fence. Can't say if it was composite but the guy who hit it was no 25 yr old spring chicken and he smoked the ball. Luckily, I only got a bruise and continued to play. The torn hamstring I got running down a flyball a couple games later put me out for a while though.
