Stammen (1-1) allowed an unearned run despite not giving up a hit or a walk in one inning Tuesday against the Dodgers, leaving him on the hook for the loss.
Stammen's throwing error allowed Austin Barnes to reach second base in the seventh inning. Reliever Tim Hill then allowed the inherited runner to score the decisive run on an A.J. Pollock double. Stammen didn't help his own cause defensively, but he's still had only one truly negative outing in five appearances this season. The 36-year-old is likely to continue seeing work in the late innings for the Padres.
