A’s ship rookie Hayden Juenger to Triple-A

Juenger returns to the minors to make room for Chris Roycroft on the active roster. The 26-year-old has allowed 16 runs on 24 hits with a 6/8 K/BB ratio across 16 innings of work in the majors this season. Amazingly, he hasn’t allowed a home run. Go figure.

Juenger will hope to make a better impression than his previous MLB action in 2026, as he’s given up nine runs in his 11 1/3 innings with the A’s thus far. He takes the roster spot of José Suarez, with Suarez placed on the IL due to a hip strain.

Juenger receives his first opportunity with the Athletics after being acquired from the Blue Jays in a small trade last month. The 25-year-old made a pair of relief appearances for Toronto earlier this year. He’s likely to operate in low-leverage spots.

Juenger was DFA’d by the Jays earlier this week. In his MLB debut, the 25-year-old gave up three earned runs over two innings in two appearances for the Jays earlier this season. Primarily a reliever the last four years, he has a 4.71 ERA and a 251/113 K/BB in 237 career innings in Triple-A. The A’s figure to stick him in their Triple-A bullpen for now.

Juenger is off the 40-man roster, and it clears room for Shane Bieber (elbow) to be activated off the 60-day injured list for his season debut Tuesday against the Astros. Juenger could see interest on the waiver wire, but if he goes unclaimed or untraded, he’ll likely report back to Triple-A Buffalo.

He allowed three earned runs in two innings with the Jays in his first MLB action, walking two and striking out none. He’ll likely be back at some point on the Buffalo/Toronto shuttle when the Jays need a fresh arm.

Juenger earns his first promotion to the majors after posting a serviceable 3.15 ERA, 1.50 WHIP and 23/8 K/BB ratio across 20 innings for Triple-A Buffalo this season. He also has three saves during that span. The 25-year-old joins Toronto’s bullpen ahead of Saturday’s contest against the division-rival Orioles and figures to operate in low-leverage spots initially.

Tiedemann — universally considered among the top pitching prospects in the game — should get a legitimate shot at cracking the Jays’ Opening Day rotation. Injuries limited him to just 44 innings over 15 minor league starts in 2023 before he concluded his season by taking home Pitcher of the Year honors in the Arizona Fall League. The 18 other players invited to major league spring training on Monday were RHP Andrew Bash, C Zach Britton, LHP Jimmy Burnette, C Phil Clarke, RHP Connor Cooke, RHP Chad Dallas, INF Luis De Los Santos, OF Cam Eden, LHP Brandon Eisert, LHP Mason Fluharty, RHP Devereaux Harrison, RHP Ryan Jennings, RHP Hayden Juenger, INF Damiano Palmegiani, OF Will Robertson, OF Alan Roden, C Brian Serven and Andres Sosa.
