Wrobleski didn't factor in the decision Sunday against the Nationals after giving up four runs on eight hits and one walk over three-plus innings. He struck out six.
The left-hander was shifted to the bullpen upon his return from forearm inflammation Tuesday, but he made just one relief appearance before retaking the mound as a starter, with Roki Sasaki (finger) unavailable. Wrobleski opened with three scoreless innings Sunday, but things fell apart in the fourth as he failed to retire any of the five batters he faced. The 26-year-old has surrendered six earned runs across five frames in his two outings since coming off the IL, and he's likely to shift back to the bullpen due to Emmet Sheehan rejoining the big-league roster Monday.
