PHOENIX -- D-backs third baseman Ryan Roberts took ground balls prior to batting practice on Friday to work on his footwork and throws to first base.

Over the past week, the 31-year-old has struggled with his throws to first. Third-base coach Matt Williams closely watched Roberts and demonstrated technique during the session.

"At times, you start thinking too much," Roberts said. "So you have to go back to the basics of making sure your feet are underneath you and you follow your throw. That means working on footwork and trying to keep your feet underneath you with ground balls."

D-backs manager Kirk Gibson noticed the issue was a result of a different arm angle Roberts has been using in his throws to first. Roberts has two errors through 11 starts at third this season, but the club isn't worried about its third baseman.

"He's getting a bad habit in getting his arm down a little bit," Gibson said. "Initially, he wasn't working on his footwork as much, now [Williams] works with him constantly about getting his feet around. It's not a concern, it's something we can correct."
