SAN FRANCISCO -- Assistant Brewers scouting director Ray Montgomery is leaving the team to become the D-backs' amateur scouting director, the Brewers confirmed on Thursday.

Montgomery spent eight seasons in Milwaukee's organization, including the past two as scouting director Bruce Seid's top aide. Montgomery joined the Brewers as an area scout for South Texas and Louisiana in December 2002 and was responsible for the scouting and signing second baseman Rickie Weeks in '03.

"Ray has been a strong and successful part of this organization and we wish him well," Seid said. "My goal is to continue to train, develop and promote our own scouts and also be open to pursuing others."

In Arizona, Montgomery will replace Tom Allison, another former Brewers scout.

The move was first reported Wednesday night by the Arizona Republic and confirmed to MLB.com by a baseball official. The D-backs were not available to comment. Seid, Montgomery, Allison and Astros scouting director Bobby Heck all once worked under the Brewers' highly regarded former scouting director Jack Zduriencik, who is now the general manager in Seattle.

The D-backs earlier this week added another man with Brewers ties in former second baseman Eric Young, who is joining Arizona as first-base coach.
