He put a buzzer on the end of the bat?
It's not a buzzer. It's an electro-magnetic fieldopoter. Without getting too technical, the "sticker" at the end of the bat senses the ball of of the pitchers arm before it hits its axis. The electro-magnetic force stagnates the spin rate ever so slightly and "pulls" the ball almost imperceptiblly towards the bat's sweet spot, allowing for harder contact and better launch angles.
This is why opposing pitchers' xWorp~ *decreased* by a .07 differential vs the Astros in day games and by a .079 in night games. (obviously, the magnetic dopplers are lower under lights.)
