What has actually been said and decided
In December 2024, during contract talks, Sato conveyed his intention to pursue MLB in the future (Jiji Press). His 2025-26 renewal then became the story of the offseason: negotiations stretched past New Year's, with the Yomiuri Shimbun reporting that talks ran long over discussions of an MLB challenge via the posting system as well as salary. On January 31, 2026 he announced a single-year renewal (reported at 450 million yen plus up to 50 million in incentives) and said of the talks: he and the club had discussed posting and salary at length, and would keep talking it over going forward (Jiji Press). No posting approval or refusal has been announced by Hanshin for Sato as of August 2, 2026. For reference, Hanshin has posted players before: Kei Igawa (to the Yankees, released January 2007), Shintaro Fujinami (Athletics, January 2023) and Koyo Aoyagi (Phillies, January 2025), per NPB's official posting-release list.
Estimated eligibility timeline
| Route | Estimated earliest timing | Basis |
|---|---|---|
| Posting | Any offseason Hanshin consents | Club decision; talks documented but no decision announced (as of Aug 2, 2026) |
| Domestic FA (7 seasons) | During the 2027 season | College draftee (2020 draft, i.e. 2007 or later) needs 7 counted seasons; 2021 + 6 = 2027 if every season reached 145 days |
| International FA (9 seasons) | During the 2029 season | 9 counted seasons; 2021 + 8 = 2029 if every season reached 145 days |
These are ceilings on speed, not predictions: NPB does not publish cumulative registered days, and Sato has had short spells off the active roster (reported farm stints in 2021, 2023 and 2024), so the actual dates could be later. The authoritative confirmation will be NPB's own FA announcements when the time comes.
Frequently asked questions
Will Teruaki Sato be posted for MLB in the 2026-27 offseason?
No decision has been announced as of August 2026. What is documented: he has told the club he hopes to play in MLB, and his January 2026 renewal followed prolonged talks about posting timing, with both sides saying discussions would continue (Jiji Press, Jan 31, 2026).
When does Teruaki Sato get international FA rights?
As of August 2026, estimated at the 2029 season at the earliest: 9 counted seasons from his 2021 debut if he reached 145 registered days every year. NPB does not publish service-day totals, and short farm stints could push the real date later.
Has Hanshin ever posted a player to MLB?
Yes, three times per NPB's official posting-release list: Kei Igawa (Yankees, released January 2007), Shintaro Fujinami (Athletics, January 2023) and Koyo Aoyagi (Phillies, January 2025).
