The Lotte Giants announced Friday they have imposed penalties on their senior executives and front office staff for their lack of oversight on the ball club, following a recent suspension of four of their players over illegal overseas gambling. The Giants announced their own disciplinary action four days after the Korea Baseball Organization (KBO) handed down lengthy bans on four Lotte players. Outfielder Kim Dong-hyeok was suspended for 50 games by the league, while three others, infielders Go Seung-min, Kim Se-min and Na Seung-yeup, were each slapped with a 30-game ban, for visiting a gaming house earlier this month near the team hotel in Tainan, Taiwan, the site of the Giants' spring training. It is illegal for South Korean nationals to gamble overseas, and the four players are currently under police investigation. The Giants were widely expected to tack on additional bans on the four players, but instead took an unusual step of disciplining Lee Kang-hun, the club's CEO, and Park Jun-hyuk, its general manager, along with front office staff in charge of personnel management.
