Vizcaino (oblique) was activated from the DL on Thursday.
The oblique strain cost Vizcaino more than a month but he has been cleared to return following a pair of rehab appearances. Although manager Brian Snitker has not said so explicitly, it seems likely Vizcaino will return to the closer role immediately despite not throwing on back-to-back days while on his rehab assignment. The 25-year-old Vizcaino has had some issues with walks but has struck batters out at a 28.8 percent clip and is 10-for-13 in save chances this season.
