Rest-of-Season Projections
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. Read Past Outlooks
Signed a one-year contract with the Athletics in March of 2025.
Summoned to big leagues
The Athletics recalled Sterner from Triple-A Las Vegas on Monday.
Analysis
Sterner was unscored upon in 24 of his first 25 appearances in the majors this season but was sent down earlier this month after allowing nine runs (eight earned) across his last two innings. He could work his way back into some high-leverage appearances but will likely be used in the middle innings initially.
