The Twins outrighted Banda (lat) to Triple-A St. Paul on Thursday, Dan Hayes of The Athletic reports.
The transaction frees a spo on the 40-man roster. Banda underwent left lat surgery in early July, but he expects to be ready for spring training. The southpaw has logged a 3.44 ERA and 144:67 K:BB over 149 regular-season innings covering the last three years.
