I figure it's just like chiefsplanet.

If that fan wants to run smack, he'd better hope he's talking to someone that is worse at it than he is with less time to kill.

The fan started running his mouth, the player should have been the bigger man and kept quiet, but I think he has the right to talk trash back. He's shitty at it to, so the fan has no place to whine.

What would possess a major leaguer, exactly, to engage in that sort of exchange with a fan?

Being a tool, mainly.

Heckling is part of the game. There's nothing wrong with how the fan was heckling. Perez runs his mouth constantly on twitter and is reduced to lame ass middle school comebacks when the fan didn't back down. He needed a teammate and an usher to have his back. "Take your dick out of my mouth"? Way to freely admit you're a power bottom Chris.

Not sure what the A's fan thinks he proved. "Chris Perez should have said $4.5 million, bitch" and left it at that.
