Medina struck out two batters and allowed one hit and one walk over a scoreless inning out of the bullpen in Friday's 8-2 loss to the Yankees.
The Athletics called upon Medina to work as an opener last Sunday but he's since shifted back to the bullpen and is likely to stick in a middle-relief role, even with Luis Severino (shoulder) landing on the injured list Saturday. For the season, Medina has collected one win and two holds while pitching to a 3.13 ERA, 1.30 WHIP and 23:11 K:BB in 23 innings over 17 appearances.
