NCAA and NFHS question

7-3-6 "If the bat breaks and is hit by the ball or hits a runner or a fielder,
no interference shall be called. If a whole bat is thrown and interferes with a
defensive player attempting a play, interference will be called.

PENALTY: The batter is out and runners return. If, in the umpire's judgment,
interference prevented a possible double play, two players may be ruled out."

Had the batter thrown the bat out in Right field and it interfered with the fielder making the play then I would agree. After the fact then all we have is a bat on the field that was hit by a bad throw. I think he is stretching his interpretation.
