GM Colletti restructures Dodgers' front office

LOS ANGELES -- Dodgers general manager Ned Colletti announced on Saturday a restructuring of his inner circle, with Vance Lovelace and Rick Ragazzo emerging with new titles and greater influence in Major League player evaluation.

Lovelace, previously a special assistant to the GM and director of player scouting, is now director of professional personnel. Ragazzo, previously a special assistant to the GM, is now director of pro scouting.

Alex Tamin, a lawyer hired after the season, has quickly assumed a significant role in player analysis and arbitration preparation as director of contracts, research and operations.

Colletti said the front office is more "streamlined" with this reallocation of responsibilities following the spring departure of former assistant GM Kim Ng, who now works for former manager Joe Torre in the Commissioner's Office.

Logan White remains assistant GM in charge for amateur (Draft) and international scouting and DeJon Watson remains assistant GM for player development (Minor Leagues). Tony Howell and Ken Bracey remain as special assistants to Colletti.

"Vance and Rick have really grown into their roles as player evaluators," Colletti said. "Vance is a very good judge of talent and an even better judge of people. He's become very important to the organization and he will spend more time in L.A. with the big league team. These changes have allowed for a more streamlined decision-making process."

Lovelace, who had a 13-year career as a pitcher, joined the Dodgers in 2001 as a scout. He originally came to the Dodgers from the Cubs in the 1983 Ron Cey trade (at the time, Colletti worked for the Cubs). Ragazzo joined the Dodgers four years ago after 17 seasons in baseball operations and scouting for San Francisco, where he worked with Colletti.

Former players Bill Mueller, Aaron Sele, Mark Sweeney, Jose Vizcaino and Juan Castro remain as special assistants to baseball operations.
