Former Oakland A's player Jeremy Giambi has died, the team said Wednesday.

Giambi, 47, reportedly died at his parents' home in Southern California. A cause of death was not yet reported. 

"We are heartbroken to learn of the passing of a member of our Green and Gold family, Jeremy Giambi," the Oakland A's said on Twitter. "We offer our condolences to Jeanne, Jason, and his family and friends."

Giambi played for the A's from 2000 to 2002 during his six-year MLB career as an outfielder and first baseman.

While on the A's, he played alongside his brother Jason Giambi. 

He also played for the Kansas City Royals, Philadelphia Phillies and Boston Red Sox.

After his career, he admitted in a newspaper interview that he had used steroids while in the big leagues. 

In 2011, he also testified that he purchased and used performance-enhancing drugs supplied by Barry Bonds' former trainer.
