MARIETTA, Ga. -- The living room of Ronald Acuña Jr.'s two-story, craftsman-style home looks more like a sports memorabilia store, replete with mementos from a career that blossomed earlier than most. All-MLB plaques and commemorative baseballs dot two sets of bookcases on each side of a white fireplace. A signed lineup card from last year's All-Star Game in Los Angeles sits on one, a Team Venezuela batting helmet from this year's World Baseball Classic rests on the other. In the middle, an oversized picture of a smiling, 20-year-old, tuxedoed Acuña posing with the 2018 National League Rookie of the Year Award overlooks it all.
