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.
