Karinchak was recalled from Triple-A Columbus on Friday.
Karinchak has saved 11 games this season but pitched himself out of a high-leverage relief job in late August after struggling to a 9.75 ERA over his last 12 innings of work. He's been good in seven Triple-A appearances, giving up two runs on three hits in six innings of work while striking out nine batters and walking three. It's not impossible that he could see a save chance or two in the final series of the season, but the team doesn't seem to have a lot of faith in him given his demotion.
