ATLANTA -- The Braves have already apologized about the tone of the meeting during which Tom Glavine learned that he was being released. But while attempting to move away from the situation, they've learned there's a chance that Glavine will file a grievance.

According to a FOXSports.com report, Glavine's agent, Gregg Clifton, has discussed this matter with a labor attorney and the players' union.

When he learned of this report on Saturday, Braves general manager Frank Wren immediately said that the club wouldn't provide a response. With the $1 million contract Glavine signed in February, he had opportunity to gain a $1 million bonus once he was placed on the active 25-man roster. He believes the Braves utilized those funds to account for the prorated $2 million salary of Nate McLouth, who was acquired from the Pirates on Wednesday, just hours after the 43-year-old left-hander learned he would be released.

"By not paying me, I think that freed up some money for them to do that," Glavine said Friday. "So I think it was much more of a business and financial situation than it was a peformance situation."  

While Glavine believes that his release was financially motivated, the Braves contend that their decision was based on the performance they'd evaluated during his Minor League rehab starts.

After evaluating Glavine's three rehab starts, the Braves determined that he would have trouble finding success at the Major League level. Going with a younger option, they've  instead inserted Tommy Hanson into their available rotation spot. 

"Our evaluation was that [Glavine] would not be successful," Wren said on Wednesday. "With the overall evaluation of the performances we saw over the last few weeks, we felt like we would have a better chance at the Major League level with our young pitchers."
