Yomiuri Giants closer Marc Kroon will return to the 2009 Japan Series champions next season, sources said Tuesday.
Kroon, 36, signed a one-year deal to join the Giants in 2008. But his contract included an option that automatically kicked in to extend his stay each year up to a maximum of three years dependent on his performances.
Meanwhile, Nippon Ham Fighters ace Yu Darvish has a stress fracture in his pitching hand, it was announced on Tuesday.
The right-hander's injury was discovered at the base of the middle knuckle in his index finger at a hospital in Sapporo on Monday.
