2026 Fantasy Outlook
Sterner opened 2025 with an impressive 18-game scoreless streak, but the right-hander allowed 13 earned runs over his next 11 outings before he was optioned back to the minors. After spending a good chunk of the month of June in Triple-A, the 29-year-old was summoned back to the majors, filling a multi-inning role for the Athletics. He was much better upon his return, posting a 2.39 ERA, 0.77 WHIP and 40:7 K:BB over his final 37.2 innings. Ultimately, Sterner led A's relievers in appearances (59), strikeouts (69) and holds (16) in 2025 while finishing second with a career-high 64.0 innings pitched. His 1.05 WHIP was a top-40 mark among qualified relievers. Sterner - who tossed more sweepers in 2025 - produced excellent results (.091 BA, .159 SLG, 46.4 percent whiff) with the pitch and could throw even more in 2026, especially if he receives save opportunities. Among current A's relievers, Sterner has one of the best profiles to close. Read Past Outlooks
Signed a one-year contract with the Athletics in March of 2025.
Picks up first win
Sterner (1-2) earned the win in Sunday's 2-1 victory over the Rangers. He allowed a hit and no walks while striking out two over a scoreless inning.
Analysis
Entering for Jacob Lopez after he failed to record an out in the sixth inning, Sterner worked out of a bases-loaded jam to preserve a one-run lead that the Athletics held the rest of the way. With starter J.T. Ginn (shoulder) exiting after 3.1 innings and Joel Kuhnel and Lopez combining to provide limited length and effectiveness, the official scorer awarded Sterner the win, his first of the season. Since allowing four runs in a blown save against the Rangers on April 16, the 29-year-old has turned in five scoreless innings and owns a 3.07 ERA and 1.50 WHIP with an 18:5 K:BB across 14.2 innings in 2026.

2025 Fantasy Outlook
Sterner will pitch in middle relief after he was claimed by the A's off waivers from the Rays in the offseason. Sterner had strong strikeout rates in the minors with a 31.4% K% at Triple-A last season. He's been prone to giving up home runs (1.36 HR/9 at Triple-A) and doesn't have great velocity. His upside may also be limited at age 28. Still, he could be a productive reliever for a team desperate for bullpen arms.
