Pepiot was optioned to Triple-A Oklahoma City on Monday, Matthew Moreno of DodgerBlue.com reports.
The Dodgers have an off day in the middle of this week and the middle of next week, so they can give most of their starters extra rest in the short term even while sticking with a five-man rotation. Pepiot could be recalled the next time the Dodgers want to operate with a six-man rotation or if someone in the rotation gets hurt.
