Clase (3-5) suffered the loss and blown save in Friday's 5-4 loss to Oakland, allowing two hits and two runs in one third of an inning.
Clase entered in the ninth protecting a one-run lead and surrendered a leadoff single to Elvis Andrus followed by a Jed Lowrie walk-off home run two batters later for his third straight blown save and third loss in four appearances. The 23-year-old righty has now allowed five runs in his last 3.1 innings, though his ERA still sits at 2.19 on the season.
