The Chicago White Sox placed right-hander Joe Kelly on the 15-day injured list Monday with a right groin strain.
Kelly, 34, is 0-1 with a 10.13 ERA in three relief appearances (2 2/3 innings) so far this season.
He is 51-33 with a 3.96 ERA in 411 career games (81 starts) with four teams since his 2012 debut.
Chicago also called up Keynan Middleton and outrighted fellow righty Jonathan Stiever to Triple-A Charlotte.
Middleton, 29, has allowed just one hit in three scoreless appearances out of the Charlotte bullpen this season.
Stiever, 25, has not pitched in a game for the White Sox since undergoing lat surgery in August 2021.
