The Chicago Cubs selected the contract of left-hander Ty Blach from Triple-A Iowa on Sunday.
In corresponding moves, the Cubs optioned right-hander Javier Assad to Triple-A and transferred right-hander Hunter Harvey to the 60-day injured list.
Blach, 35, is set to make his Cubs debut after he went 2-3 with a 5.23 ERA in five appearances (three starts) at Iowa. Over seven major league seasons, he is 23-33 with a 5.42 ERA in 156 appearances (70 starts) for the San Francisco Giants (2016-19), Baltimore Orioles (2019) and Colorado Rockies (2022-24).
The Cubs are expected to use Blach out of the bullpen.
Assad, 28, was 3-1 with a 5.88 ERA in eight appearances (three starts) for the Cubs this season and has gone 21-13 with a 3.61 ERA in 86 career appearances (57 starts) over five seasons with Chicago.
Harvey, 31, was placed on the IL last month with right triceps inflammation after going 0-1 with a 6.75 ERA in four relief appearances this season.
