Major League Baseball had been investigating claims the team illegally used a camera to steal signs from catchers to pitchers.
The team will also be fined $5 million and forfeit first- and second-round draft picks in 2020 and 2021.
The investigation was initiated after former Detroit Tigers pitcher Mike Fiers, who pitched for the Astros in 2017, went public with allegations of an elaborate sign-stealing system used by his former team. They're even reportedly planning to make their bench coach the interim manager rather than bring in somebody new.
After working out which sign corresponded to which pitch, they would tell the batter what was coming, allegedly banging on a rubbish bin inside the clubhouse to signal an off-speed pitch.
The Astros beat the Dodgers in seven games to win the 2017 World Series.
The suspensions of Hinch, Luhnow and Taubman will begin immediately and run through the 2020 World Series.
Fired assistant GM Brandon Taubman was suspended for the full upcoming season, too, but for yelling at a female reporter about how glad he was that the team acquired closer Roberto Osuna, who had been accused to domestic violence.
An MLB investigation found that Crane was not aware of the team's rules violations.
"While it is impossible to determine whether the conduct actually impacted the results on the field, the perception of some that it did causes significant harm to the game", Manfred said.
Whatever information Major League Baseball discovered about Luhnow and Hinch's roles could have easily been discovered by Crane by asking them what they knew and told Major League Baseball.
With that, Astros owner Jim Crane was asked Monday during his post-punishment press conference whether the sign-stealing scandal - and all that we now know about it - taints the Astros' 2017 title.
Takeaway: After Cora left the team to take over as Red Sox manager, the use of the replay room dissipated. Cora, now the manager of the Boston Red Sox, could face punishment for his role in the scandal and the conclusion of the still-ongoing investigation.
And in case there was any question about what clues we can draw about Cora's fate from the price the Astros will have to pay-which The Athletic has described as "unprecedented"-the signs from the sports media world are all bad".
