"His quad tightened up on him, so that's why we took him out," Hale said. "When you come out of a game with something that's tight like that, you like to give him at least one more day to feel 100 percent. With [Thursday] being an off-day, that gives him two, so we feel like he'll be really good."
Peralta is 11-for-15 with eight RBIs over his last four games, including a grand slam on Tuesday night.
Tomas left at the start of the fifth inning on Tuesday with tightness in his left calf. Hale said he does not expect it to be a concern after Thursday's off-day.
Delgado beginning rehab stint
• D-backs reliever Randall Delgado (sprained ankle) is scheduled to pitch on Wednesday night in the Rookie-level Arizona League.
After originally saying Delgado could return to the Majors this weekend, Hale said the plan is now for Delgado to report to Double-A Mobile on either Friday or Saturday to make a few appearances there before rejoining the big league club next week.
