OUT

Out · expected back around Feb 1

After undergoing right knee surgery Friday, Sterner had already been ruled out for the rest of the season. His move to the 60-day injured list is merely procedural, as it opens up a spot on the 40-man roster for waiver pickup Joe Rock. The 29-year-old Sterner logged a 6.12 ERA, 1.38 WHIP and 40:13 K:BB over 42.2 innings out of the bullpen before hitting the shelf July 18.

  • The Athletics transferred Sterner (knee) from the 15-day injured list to the 60-day IL on Sunday.

    After undergoing right knee surgery Friday, Sterner had already been ruled out for the rest of the season. His move to the 60-day injured list is merely procedural, as it opens up a spot on the 40-man roster for waiver pickup Joe Rock. The 29-year-old Sterner logged a 6.12 ERA, 1.38 WHIP and 40:13 K:BB over 42.2 innings out of the bullpen before hitting the shelf July 18.

  • The Athletics announced Friday that Sterner underwent right knee surgery and will miss the remainder of the 2026 season.

    Sterner underwent a "chondroplasty of the medial femoral condyle" and also received a PRP injection. The 29-year-old appeared in 46 games out of the Athletics' bullpen this season, logging a 6.12 ERA, 1.38 WHIP and 40:13 K:BB across 42.2 innings. He hasn't pitched since July 17.

  • Sterner will see a knee specialist at Stanford this week, per MLB.com.

    Sterner, who landed on the injured list July 18 due to right knee chondromalacia, recently felt increased soreness when throwing, prompting a visit with a specialist. A more formal timeline for his return should emerge following the right-hander's appointment. Prior to hitting the shelf, Sterner posted a 6.12 ERA, 1.38 WHIP and 40:13 K:BB across 42.2 innings of relief work.

  • The Athletics placed Sterner on the 15-day injured list Saturday with right knee chondromalacia.

    Sterner gave up six earned runs in just one-third of an inning during Friday's contest, and he'll now be sidelined until at least Aug. 2 due to his knee injury. Geoff Hartlieb will come up from Triple-A Las Vegas to fill the vacancy in the Athletics' bullpen.

  • Sterner earned his first save of the season in Wednesday's extra-inning win over the Cubs. He tossed a perfect inning while striking out one.

    Scott Barlow pitched two-thirds of an inning in Tuesday's series opener against the Cubs, so the A's turned to Justin Sterner for the save in the bottom of the 10th inning Wednesday. This was Sterner's first save of the season, and he needed just 14 pitches (10 strikes) to get the job done. The 29-year-old has been on a roll of late and hasn't allowed a run in any of his last five outings (5.1 innings). He's now 1-for-2 in save chances, but he's not expected to take the closer role any time soon.
