ATLANTA — The Braves lost 13 prospects and former general manager John Coppolella was banned for life by Major League Baseball on Tuesday for circumventing international signing rules from 2015-17.

Former Atlanta special assistant Gordon Blakeley, who was the team’s international scouting chief, was suspended from baseball for one year by Commissioner Rob Manfred.

Sanctions imposed by Manfred will leave the Braves unable to bargain at full strength for a top Latin American prospect until 2021.

Manfred said MLB’s investigation determined the Braves moved international signing bonus pool money from one player to boost another player’s contract.

Most notable among the players the Braves will lose is Kevin Maitan, an infielder from Venezuela who signed for $4.25 million in 2016.

Other “high-value” players the Braves will lose include Juan Contreras, Yefri del Rosario, Abrahan Gutierrez, Juan Carlos Negret, Yenci Peña, Yunior Severino, Livan Soto and Guillermo Zuniga.

Three more international signees – Brandol Mezquita, Angel Rojas and Antonio Sucre – were declared free agents. The team’s contract with prospect Ji-Hwan Bae, which was not yet final, was disapproved. Finally, the Braves were banned from signing prospect Robert Puason in the 2019-20 signing period.

The 13 players will be free to negotiate as free agents with other teams.

Also, the Braves will forfeit their third-round selection in the 2018 draft as punishment for offering “impermissible benefits” to an unnamed draft pick in an effort to convince him to sign for a lower bonus.

The investigation showed the players signed by the Braves in 2016-17 would have been unavailable if the team had not circumvented the rules.

Manfred said stripping the Braves of the 13 players was not sufficient punishment. He said “additional sanctions are warranted to penalize the club for the violations committed by its employees.”

Therefore, the Braves will be prohibited from signing any international player for more than $10,000 during the 2019-20 signing period. Also, the team’s international signing bonus pool for the 2020-21 signing period will be reduced by 50 percent.

The Braves already cannot give an international signing bonus of more than $300,000 for 2017-18 and 2018-19 as penalties for exceeding their signing bonus pools under baseball’s previous labor contract.

And there is still more discipline to be handed down.

Manfred said he intends “to discipline other Braves international baseball operations employees.”

Coppolella was forced to resign after the season. Former team president John Hart was moved to a senior adviser role when a new general manager, Alex Anthopoulos, was hired on Nov. 13. Hart left the team on Friday.

YANKEES: Aaron Judge is expected to be ready for spring training after he had arthroscopic surgery on his left shoulder. The procedure involved a loose-body removal and cartilage cleanup.

Judge hit .284 with 52 homers and 114 RBI in 155 games this season, helping New York make it to the ALCS, where they lost to the eventual World Series champion Astros. He was a unanimous selection for AL Rookie of the Year and finished second to Houston’s Jose Altuve in the AL MVP race.

ANGELS: Josh Paul was named bench coach. Paul spent the past three seasons as the New York Yankees’ catching coordinator.
