The Chicago Cubs selected the contract of right-hander Corbin Martin on Saturday to fill out the bullpen after right-hander Daniel Palencia went on the injured list Friday.
To make room on the 60-man roster, the Cubs transferred right-hander Cade Horton to the 60-day IL. Horton underwent Tommy John surgery on Thursday.
Palencia, 26, was placed on the IL with a left oblique strain. He had one save and did not allow a run over his first five outings of the season. He also helped Venezuela to the WBC title, not allowing a run in five appearances in the tournament with three saves.
Martin, 30, signed as a free agent with the Cubs in January after posting a 6.00 ERA over 17 relief appearances for the Baltimore Orioles last season. In 34 major league appearances (10 starts) with the Houston Astros (2019), Arizona Diamondbacks (2021-22) and Orioles, he is 2-5 with a 6.54 ERA.
Horton underwent the second Tommy John surgery of his career this week and is expected to be out until the midway point of the 2027 season. The former first-round draft pick in 2022 was 1-0 with a 2.45 ERA in two starts this season.
