If the batter PREVENTS the ball from ENTERING the strike zone by any method OTHER than hitting the ball OR a pitched ball HITS a BATTER while the BALL is IN the strike zone:

The play is considered a DEAD-BALL strike.

• The BALL is DEAD.
•  A STRIKE is given to the batter.
•  RUNNERS must RETURN to original bases occupied at the time of pitch.

In NFHS play: Intentionally preventing the ball from entering the strike zone and making a travesty of the game can result in either a warning for unsportsmanlike conduct, restriction to the bench, or even ejection based on the umpires judgment.
