Johnson is 68-years old and led the team to a record of 40-43 after he replaced Jim Riggleman in the middle of last season. Johnson has quite a lot of talent on the team and coming up in the future.
Ian Desmond, Danny Espinosa, Drew Storen, Stephen Strasburg and Bryce Harper could all help the club make a name for themselves next season in the National League East. Hopefully the division will be even more competitive than it was this season.
