Thirty-one-year-old Katsuya Kakunaka is expected to earn his domestic free agent option on September 8. The media learned on September 4 that the Chiba Lotte Marines might once again offer Kakunaka a multi-year deal. The Marines prepared two contracts last year, a three-year and a one-year deal. Kakunaka turned down the three-year contract and agreed to the one-year contract. Kakunaka later told reporters that he did not find multi-year contracts attractive. He also hinted that he was partially interested in the possibility of using his free agent option before he got too old.
