Thirty-three-year-old Hirotoshi Masui earned his domestic free agent option earlier this year. He is currently in the final year of a two year deal.
According to a report by Sports Hochi, a number of teams are keeping an eye on Masui to see what he does with his free agent option. He is first planning to sit down with the Nippon Ham Fighters before deciding what he wants to do with the option. He could be an interesting option for a team looking to bolster their bullpen.
[UPDATE 10/20 @ 10:36pm]
Masui was asked to stay during a meeting after the season. He feels needed, but is also interested in talking to other teams. According to Sponichi, there might be a gap in between what Masui wants and what the Fighters’ are offering. Masui is planning to make a decision based on what happens during his next meeting.
[UPDATE 10/29 @ 12:18am]
Masui will have his second meeting with the Fighters on October 30. Based on how discussions have gone so far, there is a good chance he will exercise his option. He is planning to make a decision after the meeting.
Masui may have been offered a one-year deal with no change in salary plus incentives during his first meeting with the team.
[UPDATE 10/31 @ 3:17pm]
Masui met with the Fighters for a second time on October 30. The Fighters may have offered a multi-year contract. Masui told reporters he received a good offer and that he wanted to make a decision about his option some time this week.
The Yomiuri Giants could be interested in his services.
[UPDATE 11/7 @ 3:27pm]
According to the latest reports, Masui will probably end up filing for free agency because he is still interested in hearing offers from other NPB teams. He is looking for a multi-year deal (the more years, the better). He could still end up staying with the Fighters.
[UPDATE 11/7 @ 11:50pm]
The media learned on November 6 that the Fighters may have offered Masui a two-year contract worth over 440 million yen (he made an estimated 220 million this year and likely got a raise). Nippon Ham is open to signing Masui even if he uses his option, but if he decides to become a free agent, it will most likely be to sign with another team.
