Corbin (6-12) was tagged with the loss Saturday against Atlanta after allowing six runs on seven hits and two walks while fanning five across 4.2 innings.
The veteran 32-year-old hurler continues to struggle and has been unable to repeat the strong performances he's had in past years with the Nationals. In fact, his 6.04 ERA would rank as a career-worst mark for him, and he has been pitching awfully of late with four or more runs allowed in six straight appearances. He owns a 7.83 ERA during that six-game stretch.
