The Twins optioned reliever Cody Stashak to Triple-A St. Paul ahead of Saturday's 1:10 p.m. game at Target Field.
Stashak struggled in Friday's 8-3 loss to the Kansas City Royals, letting all three of his inherited runners from starter Randy Dobnak score in what became a game-breaking inning.
In his place, the Twins recalled fellow right-handed pitcher Juan Minaya, 30, who has a 5.11 ERA and 1-2 record through seven games with the Saints. He previously played in the MLB level for 125 games with the Chicago White Sox.
To make space for Minaya on the 40-man roster, the Twins designated righty Dakota Chalmers for release or assignment. He's appeared in five games with Double-A Wichita this season and has a 9.49 ERA.
For Saturday's second game against the Royals, lefty J.A. Happ (2-2, 5.44 ERA) will start for the Twins against righty Ervin Santana (0-0, 2.20 ERA). See the full lineups below.
