According to FOX Sports Ken Rosenthal, pitcher Tom Glavine is considering filing a formal grievance against the Atlanta Braves for his release from the team last Wednesday.

Glavine feels his release was done for financial reasons and not to clear a spot in the rotation for hot prospect Tommy Hanson, who is making his major league debut today against the Milwaukee Brewers.

Rosenthal asked Braves general manager Frank Wren for his reaction:

Wren said the decision was made for performance reasons, not business reasons. The team promoted top prospect Hanson rather than activate Glavine.

According to the MLB collective-bargaining agreement, no player can be released from a team because of financial reasons. Glavine would have received a $1 million bonus if he had been activated from the disabled list for Sunday’s start.
