PHOENIX -- After inserting Randall Delgado into the rotation for a spot start Sunday in order to give their starters an extra day of rest, the D-backs could be in for some additional tweaking prior to next weekend's series with the Rockies.
As it stands right now, left-handers Patrick Corbin and Robbie Ray pitch back to back. Teams typically like to split their left-handers up so teams don't face them consecutively.
"[That's] something we were talking about yesterday," D-backs manager Torey Lovullo said. "There is some concern. We will have an off-day after the Colorado games, so there's a chance that we juggle that a bit.
