Russell has signed a $530,000 contract with the Kiwoom Heroes of the KBO, Jeeho Yoo of the Yonhap News Agency reports.
Russell's tenure with the Cubs ended this offseason with the team opting to non-tender him after the second baseman was handed a 40-game suspension following an alleged domestic violence incident. He did eventually appear in 82 games for Chicago but managed to hit just .237/.308/.391 and will now head overseas to continue his career.
