I hate the nickname "Joey Baseball."It's too obvious a ripoff of Manziel (whose "Johnny Football" moniker makes me cringe as well and you see how he turned out). And even then it wasn't original because "Donnie Baseball" is managing the Marlins. And he was a Yankee. However, if Rickard keeps this up, I might go with "Joey Rockstar."
I sometimes have my own nicknames for the players as I'm watching the games. I was calling Schoop "Schoopy" long before I found out they actually called him that, so I was pleased when I found out that's what they call him. I've been calling Kim "Kimmy" so I don't have to pronounce his name.
