De La Rosa will make his first start of the regular season against the Cubs on April 7.
"We looked at the first month of the season and went through the matchups, who would face different people," Hale said. "And the way we looked at it, just trying to do as much research as we could, it looks like the matchups for Corbin are better in the three-hole and Miller in the two-hole. As of right now."
If the D-backs remain in rotation throughout April, Miller would face the Rockies, Cubs, Padres, Giants and Cardinals. Corbin would face the Rockies, Dodgers, Padres, Pirates and Cardinals.
