"It's more of a review thing, it wasn't a punishment," D-backs manager Kirk Gibson said. "It was just a review thing to make sure we're all on the same page."
The D-backs do have a new backup catcher in Wil Nieves and two new infielders in Ryan Wheeler and Jake Elmore, who were called up from Triple-A Reno. So Gibson wanted them to review the signs and go through their execution points.
"No," Gibson said when asked if he planned the afternoon practice session prior to the defensive struggles. "But after what happened last night we just thought we needed to do it."
