LOS ANGELES -- With any change, there's always an adjustment involved. For Walker Buehler, the Dodgers' No.1 prospect per MLBPipeline.com, the right-hander transitioned to being a reliever after spending his entire career as a starter. Buehler, who was called up by the Dodgers on Wednesday, said he struggled in his first few outings pitching out of the bullpen for Triple-A Oklahoma City.
