The Chiba Lotte Marines said Tuesday they have signed former major league second baseman Tadahito Iguchi to a three-year contract worth ¥180 million a year plus performance bonuses of up to ¥20 million.

Iguchi will return to Japanese baseball after playing four seasons in the major leagues, where he won the 2005 World Series with the Chicago White Sox in his rookie year.

Iguchi will don the No. 6 jersey, the number worn by former Lotte star players such as three-time Triple Crown winner Hiromitsu Ochiai and Kiyoshi Hatsushiba.

"Lotte apparently wanted me the most among teams that gave me offers. I'm honored to wear the great number," Iguchi said.
