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
Moving to Triple-A
The Athletics optioned Sterner to Triple-A Las Vegas on Thursday, Martin Gallegos of MLB.com reports.
ANALYSIS
Sterner will head to the minors just one day after he made his first MLB start. While serving as an opening pitcher in front of bulk reliever Jeffrey Springs, Sterner took his third loss of the season after giving up a solo home run in his lone inning. The Athletics reinstated T.J. McFarland (groin) from the injured list in a corresponding move.
