Vida Blue -- one of the greatest pitchers in the Oakland Athletics' history -- as died.
The team announced his passing Sunday, writing ... "There are few players with a more decorated career than Vida Blue. He was a three-time champion, an MVP, a six-time All-Star, a Cy Young Award winner, and an Oakland A's Hall of Famer."
The A's add ... "Vida will always be a franchise legend and a friend. We send our deepest condolences to his family and friends during this arduous time." No other details about a cause of death were released -- the condolences, however, are pouring in all over.
