An Adrian Beltre Head-Touching Attempt, Foiled

Robinson Cano wasn't quick enough to touch Adrian Beltre's head in last night's game. Take notes from Miggy, Robinson.

What's the best theory on Beltre's aversion, outside of the obvious "he doesn't like people touching his head"? Does successfully making contact with Beltre's head give a person the ability to sock numerous dingers? It must.
