When a batter is truly focusing on where they should be focusing, they won't even pay attention to the grunts and screams. Heck, if the dugout is cheering for their hitter, it tends to drown out the pitcher anyway. Not to sound mean.....but this isn't golf. It's softball and it gets noisy. As long as the catcher is not belting out a blood-curdling scream into the earhole of the batter, causing possible injury to the ear drum, I'm good with it.
I wonder when the first vuvuzela will pop up at a tournament? Nothin' like 130 decibels blaring into your ears.....
