They should pitch more because if they pitch more or as much as they want then the grass will be more green and therefore the sky will enjoy being blue just as much one enjoys eating the well-seasoned steak at longhorns where they is a bull. Pitchers should not be limited to standing on the mound.
I am a pitcher myself and I hate only being able to pitch three innings! We should be able to pitch WAY more often than just three innings. Even in the playoff they only let you pitch like, 7 innings total! Guys, some people have good pitchers, some people have bad. Face it.
