Chargois was optioned to Triple-A Rochester on Friday, Mike Berardino of the Pioneer Press reports.
Chargois was competing for one of the Twins' final bullpen spots this spring, but his struggles assured that he would be sent down to Triple-A to begin the season. The 26-year-old allowed eight runs over 8.1 innings in camp, though his high-power arm did manage to strike out eight batters as well. He posted a 1.29 ERA with 41 strikeouts in 35.0 innings at Triple-A Rochester last year, and if he's able to show that stuff again to start 2017, it's very possible he'll spend some time in the Twins' bullpen.
