Corbin gave up two runs on six hits over 4.2 innings in a rehab start at Double-A Mobile on Sunday. He struck out three and didn't walk a batter. This was an improvement over his first rehab outing, in which he gave up four runs on four hits and two walks in 0.2 of an inning at High-A Visalia. The left-hander threw 76 pitches Sunday and is likely to make two or three more rehab starts before rejoining the Diamondbacks near the end of the month.
