The brother of MLB superstar Yu Darvish has been convicted of running a multi-million dollar gambling ring that centered around Major League Baseball games ... officials say.
Authorities in Japan say 27-year-old Sho Darvish was taking hundreds of bets on MLB games and pro baseball games in Japan back in 2015 ... and personally wagered around $2.2 million.
Investigators say Yu Darvish was NOT involved in the gambling ring -- and also note that the action was limited to a circle of friends and had no connection to organized crime.
Sho was sentenced to roughly 2 years in prison -- but the sentence was suspended for 5 years ... meaning if he keeps his nose clean and completes any other conditions ordered by the court, he won't serve time behind bars.
According to reports, Sho apologized for bringing shame to his family -- and vowed to change his last name ... but on Tuesday, the judge told him to change his behavior instead.
