"We just want to have some fun here. Delaney is hilarious and hopefully won't get me fired," said MLB social media director Dave Feldman. "We thought our followers would enjoy whatever comes out of this. We really want to use the @MLB account as a way for celebs and other public figures to interact and have fun with baseball fans.
"Baseball is America's pastime for so many people and we thought it'd be fun for some notables to have the keys to the account when it makes sense."
