They have named Luis Castillo the Opening Day starter. Sonny Gray, Tyler Mahle and Wade Miley are expected to fill three of the other spots if they’re healthy. Gray and Miley have already battled minor injuries this spring. Krall knows how important it is to have pitching depth so the Reds can find other arms if the expected starters can’t pitch.
“Rotation depth is always something you’re trying to acquire whether it’s the offseason or in season,” he said. “You talk to everybody around the league, and everyone’s looking for rotation depth. We don’t go through the year with five starters anymore. It’s about how many quality innings can you put together on your Major League club. We might have some longer guys in the bullpen to help with the rotation depth if we have some guys starting a little slow, but I think we’re OK, at this point, knock on wood, with where we are. Some of the rotation depth might actually start in the in the big-league bullpen, as opposed to just being a Triple-A.”
