"Obviously a little scary, but didn't flinch, got right back up there and overall threw the ball well," Bradley said of the comebacker. "Arm felt good, face felt well, and just overall ready to get going again."
After he hit the ball, Pennington turned to GM Dave Stewart, who was standing behind the cage, and jokingly asked if he was going to be released.
"I didn't see him flinch at all," D-backs manager Chip Hale said. "He pitched like it was normal, with no screen. It was good."
