Corbin (elbow) covered 3.2 innings in an extended spring training start Monday, conceding no runs and striking out eight batters. The results should be taken with a grain of salt since they came against a smattering of low-level Diamondbacks prospects, but by all accounts, the lefty threw the ball well during the outing. According to manager Chip Hale, Corbin's fastball hovered around 94 miles per hour, and 36 of his 51 pitches checked in as strikes. Corbin has now made four starts at extended spring training, and after the Diamondbacks check up on the health of his elbow Tuesday, it's possible he could be cleared to begin a rehab assignment in the minor leagues. He'll probably make for a quality stash option now that he looks to be only a couple rehab starts off rejoining the Diamondbacks.
