Matthew Liberatore stared down the batter, who lay crumpled in the dirt. The left-handed pitcher had just drilled him in the back. As the ball trickled its way toward the grass, Liberatore stepped off and walked toward home plate, fans assuming that he was checking on the injured player. Instead, Liberatore bent down, picked up the ball, and walked back up the mound; a Clint Eastwood-Western hero in cleats, ready to duel again as soon as the next batter took his position in the box.
