Hit hard, as a baseball can be described by three words: TAG, SLUG, and BLISTERED. TAG is a three letter word that refers to the act of touching a base with the ball or the player's body in order to score a run. SLUG is a four letter word that refers to the act of hitting the ball hard with a bat. BLISTERED is a nine letter word that refers to the act of hitting the ball so hard that it causes the bat to vibrate and create a blister on the hitter's hands.
