The Reds recalled Johnson from Triple-A Louisville on Sunday.
Johnson will be up in the big leagues for the third time this season, restoring depth on the Reds' bench after Michael Toglia (shoulder) was placed on the 10-day injured list in a corresponding move. During his previous two stints with the Reds, Johnson logged just 14 total plate appearances over 12 games. He'll likely be in line for limited playing time this time around too.
