Ortega was reassigned to the Twins' minor-league camp Thursday, Do-Hyoung Park of MLB.com reports.
Ortega split time last season between the Angels and their Triple-A affiliate, racking up 33 strikeouts in 34 major-league innings alongside a 3.71 ERA and 1.47 WHIP. His spring numbers were solid too, so he will return to Triple-A and likely be one of the top candidates to be called up should the Twins need more depth in their bullpen.
