By all accounts, Atlanta Braves outfielder Ronald Acuna is the best prospect in the minors. Baseball America, Baseball Prospectus, and ESPN all ranked Acuna as the game's No. 1 prospect going into spring training. Although it is unlikely Acuna will break camp with the Braves -- for service time reasons, not because he isn't MLB ready -- the team is already letting him know how they want him to conduct himself. MLB.com's Mark Bowman reports the Braves want Acuna to wear his hat straight: The Braves want Acuna to wear his hat straight and maintain a professional appearance while in uniform. But they do not want to change much about the fun-loving, flamboyant approach that has made him one of the game's most exciting young players. "The main thing he needs to remember is keep your head straight and respect [your surroundings]," Jones said. "Be humble, but a humble-cocky." Are we seriously doing this in 2018? Still complaining about how players wear their hats? It was a Very Big Deal when Ken Griffey Jr. first wore his hat backwards during the Home Run Derby more than 25 years ago. We're still doing it now?
