LeBron James called out MLB commissioner Rob Manfred over the handling of the sign-stealing scandal involving the Houston Astros.

The Astros were found to have stolen signs of opposition teams en route to winning the 2017 World Series, as well as for part of the 2018 campaign.

General manager Jeff Luhnow and manager A.J. Hinch were subsequently fired by the team in January after they were initially suspended for the entire 2020 season by the league, while the Boston Red Sox dismissed manager Alex Cora.

The fallout from the scandal continued on Tuesday after New York Yankees star Aaron Judge labelled the punishment "weak" and NBA icon James weighed in via social media.

James – a three-time NBA champion and four-time MVP – tweeted: "Listen I know I don't play baseball but I am in Sports and I know if someone cheated me out of winning the title and I found out about it I would be f****** irate! I mean like uncontrollable about what I would/could do!

"Listen here baseball commissioner listen to your players speaking today about how disgusted, mad, hurt, broken, etc etc about this.

"Literally the ball is in your court [or should I say field] and you need to fix this for the sake of Sports! #JustMyThoughtsComingFromASportsJunkieRegardlessMyOwnSportIPlay."

James' comments came after he announced his first children's book will be released in August.

The 35-year-old – who is also set to feature in the next 'Space Jam' movie – has teamed up with HarperCollins Publishers for the picture book titled 'I Promise'.

"Books have the ability to teach, inspire, and bring people together. That's why these books, and the opportunity to get children and parents reading together, mean so much to me," James said.

"Most importantly, we wanted to make sure these stories are ones that every single kid can see themselves in."
