Sean Rodriguez has issued an apology on Twitter for his actions in Wednesday night's bench-clearing scuffle and for pummeling a cooler in the Pittsburgh Pirates dugout after his ejection.

Pirates reliever Tony Watson drilled Chicago Cubs ace Jake Arrieta with a fastball in the top of the seventh inning to spark the scuffle. Arrieta and Watson exchanged words near home plate, and the bullpens and benches briefly emptied onto the field.

Rodriguez appeared to throw a punch during the scuffle, and he accused David Ross of grabbing him by the neck in the scrum.

After his ejection from the National League wild-card game, the Pirates utility man proceeded to give the unsuspecting water cooler a series of one-two combinations, eventually sending it tumbling to the ground.
