Here's a solution. Go back to the way it used to be and players police the game in this situation. Quit tossing pitchers for hitting a guy after one of their teammates gets hit. Retaliation was a strong motivational tool and kept people in line.
As it is now a team gets a free shot and is stupid not to take it. Team A hits team B. Both teams get warned which is stupid on steroids.
Team B pitcher is now leary of pitching inside for fear of hitting Team A and getting tossed. Advantage Team A. The TC should use this strategy come playoffs.
