Hall Of Famer Roberto Alomar Banned From MLB After Sexual Misconduct Allegation

Hall of Famer Roberto Alomar -- one of the greatest second basemen of all time -- has been banned from Major League Baseball ... after an investigation into sexual misconduct claims from 2014.

Commissioner Robert Manfred announced the move on Friday ... saying 53-year-old Alomar has been terminated from his gig as a league consultant and placed on the "Ineligible List."

The ban, Manfred says, comes after MLB hired a law firm to investigate claims of sexual misconduct made by a "baseball industry employee," who came forward earlier this year about the alleged incident that happened in 2014.

After the investigation, it was determined Alomar violated MLB's policies ... resulting in severe punishment.

"We are grateful for the courage of the individual who came forward," Manfred said Friday. "MLB will continue to strive to create environments in which people feel comfortable speaking up without fear of recrimination, retaliation, or exclusion."

The Toronto Blue Jays followed suit by severing ties with Alomar, who was serving as a special assistant to the team ... and going one step further by scrubbing him from the team's "Level of Excellence."

Of course, Alomar was a star in the '90s -- he made 12 All-Star teams, won 10 Gold Gloves and won 2 World Series championships ... and was inducted into Cooperstown in 2011.

The Jays are also taking down Alomar's banner at the stadium, which honored his retired number #12 with the organization.

Alomar addressed the punishment minutes ago ... saying, "I am disappointed, surprised, and upset with today's news."

"With the current social climate, I understand why Major League Baseball has taken the position they have."
