Thirty-eight-year-old Hisashi Takeda is not ready to retire and is planning to leave the Nippon Ham Fighters to pursue playing opportunities with other teams. The Fighters approached Takeda earlier this month and suggested that he retire.
Takeda has had problems with his knees the last few years. He had surgery on both his knees in 2015 and made it back to the active roster on July 27, 2016. He made the opening day roster this year, but was taken off the active roster in May with knee problems. He more recently pitched two shutout innings during a Ni-gun game against Yokohama on August 26.

The media learned today that the Chunichi Dragons might be interested in Takeda. Chunichi is still looking to bolster their bullpen. They also have a connection to Takeda through Shigekazu Mori: they are both Komzawa University graduates.
