Authorities in Japan say 27-year-old Sho Darvish was taking hundreds of bets of 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.
