Arencibia, Russ Adams, and to a lesser extent Bautista.
I hated Adams the player but didn't mind him as a person. I hate Bautista as a person but like him as a player. I hate JP as a person and a player, he is just the worst.
What a douche.
He's having fun because it's spring training and these games don't matter. Once the season starts and the reality of his staggering suckitude sinks in, fun will be in short supply.
