Funny that there were two separate threads after the Preakness which could have been connected but weren't:

Thread 1: The possibility that Thunder Gulch was "electrically aided" in his Derby win.

Thread 2: The contortion of Scrappy T after being struck by Dominquez' whip in the Preakness. I am not saying that Dominquez (who took too much heat for his Preakness ride, IMO) carried a battery, but I feel confident that said device is still used in in some instances in morning training.

The way it used to work was that an exercise rider or groom would plug the horse in the morning, and then the jock, in the afternoon, would merely have to go near the spot where the horse had been hit to get the desired result.
