Vizcaino (oblique) is progressing and should return within a couple weeks, David O'Brien of the Atlanta Journal-Constitution reports.
Until then, Jim Johnson will remain the closer in Atlanta, and it's reasonable to think that the veteran may be a target for clubs looking to bolster their bullpen at the upcoming waiver trade deadline. A more precise timetable for Vizcaino's return should become available if he's sent on a minor league rehab assignment prior to his activation from the disabled list.
