In a corresponding move, the Twins reinstated left-handed pitcher Caleb Thielbar from the 15-day injured list. He had been sidelined with a right oblique strain.
Kirilloff, 25, is hitting .270 with 13 doubles, eight home runs and 32 RBIs in 69 games this season.
Thielbar, 36, is in his seventh season with the Twins (2013-2015, 2020-2023). He missed 46 games before making two rehab appearances with Triple-A St. Paul, where he threw two scoreless innings.
In 12 appearances with the Twins this season, he is 0-1 with a 1.74 ERA over 10⅓ innings pitched.
The Twins released Thielbar in 2015 and re-signed him before the 2020 season. In between, he played independent league baseball and spent time in the minor leagues.
