The Reds reassigned Busenitz to minor-league camp Tuesday.
Busenitz was one of seven players cut Tuesday as the Reds reduce their group at big-league camp to 61 men. The right-handed reliever previously made 51 appearances in the majors with the Twins between 2017 and 2018 before spending the last four years overseas with the Tohoku Rakuten Golden Eagles of Japan's Nippon Professional Baseball.
