It doesn’t always happen this way. A rookie with plenty of potential comes along and veterans help show them how to be a professional baseball player. The Miami Marlins are counting on Isan Diaz to become a future star at second base. Manager Don Mattingly is counting on veterans in the clubhouse to aid his growth as a complete player.
Diaz has been the hottest topic in the Marlins minor league system this season, pushing through and owning pitchers in the Pacific Coast League. Writers like myself putting our words on websites, begging the question of when the move to the main roster would take place and watching Diaz hit a home run against Jacob deGrom in his first game as a Major Leaguer while his father was being interviewed.
