Every bit as much proof as there is that Brady's footballs were underinflated.
I notice there's no denial there that the bat was corked. That's a typical Yankee fan's response. Here's what a third party teammate of Dent's had to say about it:
Acccording to Mike Torrez, `Mickey (Rivers) told me two years ago that Bucky`s bat was corked. If I had known that, I would have thrown him a spitter. Maybe that`s what I should throw Monday -- a nice wet one. No, he`ll get the same pitch.`
Now smirk for me.
