The Atlanta Braves sacked general manager Frank Wren on Monday, just a day after the team was eliminated in the National League playoff race.

USA Today reported that Braves CEO Terry McGuirk was frustrated with how the team dwindled late in the season after being considered as one of the top contenders in the National League.

Braves team president John Schuerholz said, though, that they had been considering making changes since the summer, even during the time that they were still on top of the NL East standings. Aside from Wren, executive vice president and assistant GM Bruce Manno was also sacked.

"I would say it was cumulative; I can't tell you exactly what period of time," Schuerholz said via MLB.com. "But as we began to examine things in our farm system and our scouting department and on our Major League club, it was a cumulative thing. I can't give you the exact date."

Schuerholz also revealed that they almost made the decision to make a front-office shakeup midway through the season, but they opted to do it just on Monday to avoid hurting the team's chemistry.

"It was time for the organization's well-being," Schuerholz said. "It was time, having been eliminated from any postseason possibility, rather than continue to wait, that it would give us an opportunity to form our committee and start this transition a week sooner than perhaps, and we thought it was the right day."

Wren, who has been with the club for 15 seasons, became the first Braves GM to be fired since 1990, when the club parted ways with Russ Nixon.

With Wren out of the team, John Hart will take over as interim GM, but the MLB Network analyst made it clear, though, that he is not eyeing to take the job permanently. Hart, along with Hall of Fame manager Bobby Cox and Schuerholz, will lead the search for a new GM.

"No, I will not seek the job," Hart said. "It's been discussed, but at this stage we are going to talk to a lot of people. It has not been ruled out, but it's not something I'm knocking down the door to do."
