Nippon Professional Baseball will ban three Yomiuri Giants pitchers indefinitely for their involvement in a gambling scandal and fine the team ¥10 million, NPB Commissioner Katsuhiko Kumazaki said Tuesday.

Earlier in the day, sources said Tokyo police have interrogated the players, Satoshi Fukuda, Shoki Kasahara and Ryuya Matsumoto, who have admitted betting on baseball games.

During the questioning, which was conducted on a voluntary basis, all three confirmed that they wagered on games, the sources said.
