Mets to introduce Sandy Alderson

NEW YORK -- Sandy Alderson will officially be introduced as the 12th general manager in New York Mets history at a 2 p.m. ET news conference Friday, the team announced.

Alderson will receive a four-year contract with the team, two sources close to the situation told ESPNNewYork.com on Thursday.

Baseball commissioner Bud Selig is allowing Alderson, 62, to leave his post as a consultant for Major League Baseball to lead the organization's baseball operations department. He was in the Dominican Republic on Thursday wrapping up his MLB responsibilities in Latin America.

"I think it's in the best interest of baseball," Selig said in San Francisco before Game 2 of the World Series. "I've known Sandy for 30 years. I have enormous respect for Sandy both professionally and personally."

Alderson served as the Oakland Athletics GM from 1983-97. He more recently served as CEO of the San Diego Padres, until stepping down in March 2009 after an ownership change.

With roughly $130 million committed to payroll for 2011 before any offseason activity, Alderson may face at least a two-year process in reshaping the organization in his vision.
