The Orioles announced that they have selected left-hander Josh Walker to their roster. Right-hander Trey Gibson was optioned to Triple-A Norfolk in a corresponding active roster move. To open a 40-man spot, outfielder Heston Kjerstad was transferred to the 60-day injured list.
Walker, 31, has generally put up good numbers in the minors but has struggled in limited big league opportunities. He finished last season on Baltimore’s roster after they claimed him off waivers in August. They then signed him to a major league deal for 2026 and designated him for assignment a few days later. That may seem like a strange sequence but the O’s were presumably hoping that the salary, which has not been publicly reported, was enough to get him through waivers to be stashed as non-roster depth. This didn’t immediately pay off, as Atlanta claimed him in November. Baltimore was able to claim him back in December and then finally outrighted him in January.
He has tossed 14 1/3 innings for Norfolk this year, allowing 4.40 earned runs per nine. That ERA doesn’t jump off the page but he has perhaps deserved better. His 8.9% walk rate is around average while his 28.6% strikeout rate and 51.5% ground ball rate are both comfortably better than par. His 61.6% strand rate in that small sample is on the unfortunate side, which may have pushed some extra runs across, which is why his 3.48 FIP is roughly a run better than his ERA.
As mentioned, Walker has often done well in the minors without major league success. He has a 6.59 ERA in 27 1/3 big league innings. But dating back to the start of 2022, he has thrown 146 minor league innings with a 3.95 ERA. His 11.4% walk rate in that sample is high but he paired that with a 30.3% strikeout rate. He will now give the Orioles a fourth lefty in their bullpen alongside Keegan Akin, Dietrich Enns and Grant Wolfram. Walker still has one option remaining and can be easily sent back to Norfolk in the future.
Kjerstad has been on the 10-day IL all season due to a right hamstring strain. His 60-day count is retroactive to that initial IL placement, so he’ll be eligible for reinstatement in a few weeks. He began a rehab assignment on Saturday. Rehab assignment for position players can last 20 days, so the length of that rehab assignment roughly aligns with his IL timeline. If he is able to come off the IL later this month, he still has an option and could be bound for more time in the minors.
