Chargois was optioned to Triple-A Rochester, MLB.com's Rhett Bollinger reports.
The Twins claimed reliever Neil Ramirez off waivers from the Brewers on Sunday, and needed a roster spot to make room for the new bullpen option. It will come at the expense of Chargois, who was just added to the Twins on Friday. He was shelled for five earned runs over 0.2 innings Saturday, so it's no surprise to see him packing his bags again this soon.
