Del Castillo is out of the lineup for Sunday's game against the Phillies.
The left-handed hitter had been in the lineup at designated hitter or catcher in Arizona's last four games, but he'll hit the bench Sunday against righty Andrew Painter. At least until the Diamondbacks get one or two of Gabriel Moreno (back), Carlos Santana (adductor), Pavin Smith (elbow) and Lourdes Gurriel (knee) back from the injured list, Del Castillo should have a fairly clear path to a strong-side platoon role.
