• Catcher Chris Herrmann is once again experiencing issues with his right hamstring and will be limited to pinch-hitting duty during the series with the Giants.
Herrmann originally experienced cramping in the hamstring June 26 in Colorado. He started behind the plate Wednesday, but left the game early when he experienced some discomfort in the hamstring.
D-backs manager Chip Hale said the team hoped Herrmann will be fully healthy when the second half starts next Friday.
