Anderson will be recalled from Triple-A St. Paul ahead of Tuesday's game against the Guardians, Ari Alexander of 7 News Boston reports.
Anderson's last big-league appearance dates back to April 21, when he allowed one run on four hits while fanning two over two innings as a member of the Red Sox. The Twins claimed him off waivers July 11, and he'll likely make his team debut Tuesday in a bulk-relief role behind opening pitcher Kendry Rojas.
