The Atlanta Braves consider Matt Adams expendable and have placed him on the trade block.

Atlanta acquired Adams to fill in for the injured Freddie Freeman last season. Freeman has returned to full health.

The Braves are attempting to move Adams by Friday, which is the deadline for teams to tender contract offers to their arbitration-eligible players.

Atlanta Braves prospect Ronald Acuna earned the Joe Black Most Valuable Player Award for the Arizona Fall League after slashing .325/.414/.639 with seven home runs in 23 games.

At 19 years old, Acuna is the youngest player in AFL history to take home the honor. The outfielder will turn 20 in December.

John Hart has stepped down as senior advisor for the Braves, effective immediately, the team announced Friday.

"This was a difficult decision, but it's one that I made with the best interests of the Atlanta Braves in mind," Hart said in a statement. "With the hiring of Alex Anthopoulos as general manager, this organization is in great hands. I believe that the talent of the Major League players, combined with the young talent soon to arrive, makes the Braves poised for a great run of success.

"This is a good time to step aside and let Alex and his group put their stamp on this great franchise. I still have a tremendous passion for this great game, and I plan to stay active and contribute to the game."

The Atlanta Braves will "definitely" lose some prospects that were signed out of Latin America in the wake of a league investigation into what has since been reported to be an "unprecedented" level of rules violations on the international market and in the domestic amateur draft.

John Coppolella and Gordon Blakely resigned as general manager and scouting director, respectively, last month.

The Atlanta Braves will name Alex Anthopoulos their new general manager, according to a source.

Anthopoulos is expected to make final decisions on all baseball matters in Atlanta, though John Hart remains with the team as president of baseball operations.

The former Toronto Blue Jays GM replaces John Coppolella, who resigned last month amid an investigation into violations in the international player market.
