Twitter's benches empty over Keith Hernandez's Ronald Acuna Jr. take

Ronald Acuna Jr. wasn't about to hit a fourth straight leadoff homer, Marlins pitcher Jose Urena made sure of that by plunking him with the first pitch.

Baseball's unwritten rules strike again, unfortunately.

And they live on because of old-school guys like Keith Hernandez, who wasn't too busy with the New York Mets broadcast to comment.

"They're killing you. You lost three games. He's hit three home runs. You gotta hit him," Hernandez said from Baltimore. "I'm sorry, people aren't going to like that.
