Owen Thomson is emerging as a steady, high-leverage lefty for Oakland
In the 2026 season, Owen Thomson has been a useful arm for Oakland, working mostly in relief with a 2-0 record and a 3.65 ERA across 19.1 innings, while striking out 15 and limiting opponents to a .268 average. He’s shown he can stabilize innings with efficient, low-drama outings, including a 2.2-inning scoreless win at Youngstown State and a three-strikeout relief appearance against Wright State. At 5'10" and 200 pounds, Thomson looks like a grinder-type left-hander who can give a staff reliable, situational innings rather than flashy stuff.
