Ozzie Guillén and Frank Thomas dismiss the idea that Yermín Mercedes’ home run violated a code: ‘The unwritten rules have changed. … Everybody’s having fun.’

“This is major-league baseball,” the former slugger said. “When you go up there, you’re here to do well. If you don’t do well, they will get rid of you. So, I’m sorry, the unwritten rules have changed a little — excuse me, not a little, a lot. … In the ’90s, when we played, (swinging at a 3-0 pitch in a rout) would never happen. But today? Everybody’s having fun.”
