Chiba Lotte Marines infielder Tadahito Iguchi announced Tuesday he is drawing the curtain on his 21-year career at the end of the season.

"I had decided last year. I want to show what my baseball career has been about in the remaining limited number of trips to the plate," the 42-year-old Iguchi, NPB's oldest active position player, told a news conference at Zozo Marine Stadium.

"I've always been thinking when would be the right time to quit. ... I want the fans and those who supported me to come and watch me as much as they can."
