The Cincinnati Reds placed right-hander Tony Santillan on the 15-day injured list Friday with a left oblique strain.
The move is retroactive to Tuesday for the 29-year-old reliever, who is 1-4 with five saves and a 5.23 ERA in 34 games out of the bullpen.
Santillan is 7-16 with 16 saves and a 3.36 ERA in 193 career games (five starts) since making his major league debut with the Reds in 2021.
Cincinnati recalled right-hander Zach McCambley from Triple-A Louisville in a corresponding transaction.
McCambley, 27, made his MLB debut on June 3 and has no decisions and a 6.75 ERA in three relief appearances.
