General manager Brian Cashman announced the decision through director of media relations Jason Zillo. The Yankees are holding professional scouting meetings in New York, which opened on Sunday and will continue into the middle of the week.
The organization has not named an immediate replacement. Luis Sojo is managing within the organization at Class-A Tampa and is thought to be a possibility, while Willie Randolph -- dismissed as the Mets' manager in June -- served 11 seasons on the Yankees' coaching staff and could merit consideration for the post.
Meacham was one of two original selections that manager Joe Girardi made for his coaching staff upon being named the Yankees' manager last November. Meacham replaced Larry Bowa, who followed former manager Joe Torre to the Dodgers.
A former Major League infielder who played six seasons with the Yankees from 1983-88, Meacham was also Girardi's third-base coach with the Marlins in 2006. Bullpen coach Mike Harkey was also tabbed by Girardi for the staff and is expected to remain for the 2009 season.
"Whenever you lose a friend on your staff, it's going to be tough," Girardi said in a statement released through the team. "However, as an organization, it was time to make a change. Bobby is a good baseball man, but moving forward we realize changes are going to have to be made in various areas of the club."
In addition, special pitching instructor Rich Monteleone was dismissed by the club. A former first-round pick of the Tigers who pitched 10 seasons in the big leagues with the Mariners, Angels, Yankees and Giants, Monteleone had been a Yankees instructor for the past four seasons after serving as a bullpen coach from 2002-04.
Hitting coach Kevin Long is the only current coach with a contract for next season, as he enters the second year of a three-year deal worth approximately $1 million. Bench coach Rob Thomson, first-base coach Tony Pena and pitching coach Dave Eiland are all expected to return.
