OAKLAND, Calif. -- The Oakland Athletics have selected the contract of Australian native Jack O'Loughlin and recalled fellow pitcher Tyler Ferguson from Triple-A Las Vegas on Saturday.
The moves came after the A's placed right-handed pitcher Ross Stripling on the 15-day injured list with a strained right elbow and designated right-handed pitcher Brandon Bielak for assignment.
O'Loughlin was a non-roster invitee with the A's this spring after signing a minor league contract on Nov. 13. The 24-year-old will be making his big league debut when he plays. He was 1-2 with a 5.12 ERA in 10 appearances, including eight starts with Las Vegas and is16-20 with a 3.76 ERA in 98 games overall, including 66 starts in six seasons in the minors.
He was signed by Detroit at age 16 on July 16, 2016, and spent two seasons in the Australian Baseball League before coming to the United States in 2018.
Ferguson played with the A's from May 7-20, posting a 5.68 ERA in six relief appearances in his Major League debut.
Stripling has been in the A's starting rotation and is 1-9 with a 5.82 ERA in 11 starts.
Bielak was acquired from Houston for cash considerations on May 16 and had a win and a 3.18 ERA in three relief appearances.
