The incident occurred as the Arizona relievers were playing catch in the outfield while the Cardinals were going through batting practice.
"He's ready to rock today," Hale said. "They were out there doing some throwing, some drills, and he got hit on the chin, like a right cross."
• Infielder Chris Owings is mired in a 1-for-22 slump. Offseason surgery on his left shoulder forced him to change his mechanics at the plate, going from a one-handed finish to keeping both hands on the bat.
"He's searching," Hale said. "Mechancially, since the surgery, he's changed some things, and I think that in doing that, patience on our part is needed, patience on his part. It's just difficult. I just think he doesn't feel as comfortable yet."
