Shigekazu Mori will be traveling overseas for about two weeks in early November. He will be checking on talent and handing off his contacts to Yui Tomori (international scout). Dayan Viciedo and Jordan Norberto are currently the only two foreign players set to return next year. The Chunichi Dragons usually carry six foreign players (three pitchers and three hitters).
