Matt Joyce hits a BP ball right back into the pitching machine (VIDEO)

A Tropicana Field camera happened to be rolling when Matt Joyce hit a batting practice ball right back into the pitching machine Thursday night.

Seems this mechanical arm didn't appreciate the Rays leftfielder's dangerous comebacker and immediately spit the the ball back at Joyce — who flinched at the surprise brush back throw — for another strike.

This temperamental robotic arm — with a retaliatory demeanor — just might be the Bob Gibson of pitching machines.
