Schreiber allowed two runs on one hit and one walk while striking out one over two-thirds of an inning in Friday's 12-8 loss to Baltimore.
Schreiber, who has pitched well out of the bullpen, was caught up in a meltdown. He recorded a hold in the outing, but he and three other relievers combined to allow 10 runs on 10 hits and three walks over the final three innings. The Red Sox have blown 12 of 20 save chances and the staff owns a 5.40 ERA in the eighth inning or later.
