Jack Perkins

Perkins earned his first big-league promotion in June 2025 after he had collected a 2.86 ERA and 68:20 K:BB over his first 44 innings at Triple-A Las Vegas. The Athletics initially used the 26-year-old as a multi-inning reliever, even giving him a save chance at one point because a Mason Miller trade was in the works. Perkins' final four outings came in the rotation and they were less successful, as he held a 5.68 ERA and 18:11 K:BB over 19 frames before going down with a strained shoulder. As long as he's healthy, Perkins should get another chance to start for the Athletics in 2026. It's worrisome, though, that the righty missed significant time with a lat injury in 2024 and then a shoulder issue in 2025. Perkins also must again pitch his home games at Sutter Health Park, where he held a 6.61 ERA in 2025 (versus a 2.42 ERA on the road). Read Past Outlooks
