Thornton (3-3) took the loss against the Athletics on Tuesday, allowing an earned run on two hits and a walk over one-third of an inning. He struck out one.
Thornton was tasked with preserving a 2-2 tie when he entered in the ninth, and after retiring the dangerous Brent Rooker looking, he never recorded another out. Seth Brown would subsequently walk it off for the Athletics with a single that plated JJ Bleday, snapping an eight-appearance scoreless streak for Thornton and saddling him with his first loss since July 22. The veteran right-hander has been a mostly effective option for Seattle, but his presence in a high-leverage spot Tuesday may have been due to the fact closer Andres Munoz is battling elbow soreness.
