I seem to remember a time when frustrated pitchers worked their aggression out on batters, by throwing nasty fastballs up at their eyes, or just plain beaning them. But in this day and age, when teams get warnings before the game even starts, it seems they have to find other outlets for their anger. Kenny Rogers and Oliver Perez have not found the proper outlets. Some advice to all those hotheaded hurlers out there: you might want to keep some stress balls handy, or maybe load up some soothing nature sounds on your iPods, because breaking bones on water coolers and laundry carts? Not really going to make you feel any better.
