A.J. Hinch apologised for failing to stop the Houston Astros' alleged sign stealing in 2017.
The Astros fired general manager Jeff Luhnow and manager Hinch after the duo were suspended following an MLB investigation into allegations of sign stealing.
Luhnow and Hinch were given year-long bans by MLB while Houston were fined $5million and have been forced to forfeit their first and second-round picks in the 2020 and 2021 drafts.
In a statement, MLB commissioner Rob Manfred said the Astros were warned about the league's policies on sign stealing in September 2017 and "took no action" to comply with these during their run to a maiden World Series title later that season.
Hinch released a statement of his own later on Monday, apologising for failing to stop the Astros' sign stealing.
"I appreciate commissioner Manfred's unwavering commitment to upholding the best interests of baseball. I regret being connected to these events, am disappointed in our club's actions within this timeline, and I accept the commissioner's decision," he said.
"As a leader and Major League manager, it is my responsibility to lead players and staff with integrity that represents the game in the best possible way. While the evidence consistently showed I didn't endorse or participate in the sign stealing practices, I failed to stop them and I am deeply sorry.
"I apologise to Mr. [Jim] Crane for all negative reflections this may have had on him and the Astros organisation. To the fans, thank you for your continued support through this challenging time - and for this team. I apologise to all of you for our mistakes but I'm confident we will learn from it - and I personally commit to work tirelessly to ensure I do.
"My time in Houston has provided some of the greatest moments in my career and those memories will always be near and dear to me and my family. I regret that my time with the Astros has ended, but will always be a supporter of the club, players, and staff I've had the privilege of working alongside. I wish them the best in the future of the game I love."
