The Oakland Athletics placed right-hander Ross Stripling on the 15-day injured list Saturday with an elbow strain and selected the contract of left-hander Jack O'Loughlin from Triple-A Las Vegas.

To make room on the 40-man roster for O'Loughlin, right-hander Brandon Bielak was designated for assignment.

Stripling, 34, was 1-9 with a 5.82 ERA in 11 starts for Oakland this season. Over nine MLB seasons, he is 39-52 with a 4.09 ERA for the Los Angeles Dodgers (2016-20), Toronto Blue Jays (2020-22), San Francisco Giants (2023) and A's.

O'Loughlin, 24, is a native of Australia who is appearing in the major leagues for the first time. Previously a member of the Detroit Tigers organization, O'Loughlin was 1-2 with a 5.12 ERA in 10 appearances (eight starts) at Triple-A Las Vegas this season.

Bielak, 28, was 1-0 with a 5.09 ERA in 13 relief appearances for the Houston Astros and A's this season.
