One of the biggest dominoes of the impending MLB offseason has fallen, adding a massive free agent bat to a pool that is relatively light on them.
The Hanshin Tigers of Nippon Professional Baseball announced that they will approve the posting of superstar infielder Teruaki Sato to MLB this offseason. Sato, who will play next season at 28 years old, won the Central League Triple Crown in 2026, batting .306 with 39 home runs and 106 RBIs. The lefty-swinging slugger put himself in line for his second consecutive Central League MVP Award.
Once Sato has officially entered the posting system, all 30 MLB teams will have a 45-day window to negotiate with him. As Sato is over 25 years old, there will be no restrictions on the deal he signs with his new MLB club, unlike when the Dodgers had to use international bonus pool money to acquire 23-year-old Roki Sasaki ahead of the 2025 season. Hanshin will additionally receive a to-be-determined “release fee” based on the value of Sato’s contract with his new MLB club.
In the unlikely event Sato does not reach an agreement with an MLB team before his 45-day posting window ends, he would return to Hanshin for 2027 and cannot be posted again until next offseason.
Sato will instantly become one of the most intriguing bats available this MLB offseason, if not the best bat on the market, due to his combination of past success and age. MLB Network insider Jon Heyman previously linked the Mets, Yankees, Dodgers and Phillies to the Japanese star, though his market could quickly amplify once his posting is official.
Sato is a third baseman by trade, spending the vast majority of his NPB career at the hot corner. He won the NPB equivalent of a Gold Glove -- a Golden Glove -- for his defense in 2025. However, there are some concerns about his long-term fit on the infield, like Munetaka Murakami before him. It’s possible some MLB teams would try to follow the model the White Sox set with Murakami this season and have Sato learn first base. Sato has also played in the outfield in 262 NPB games, according to Baseball-Reference.
There won’t be many concerns about Sato’s offensive impact. His massive 2026 campaign followed another standout year in 2025, when he earned the Central League MVP by crushing 40 home runs with a .924 OPS. These two seasons have represented a step forward for Sato, though he had been a productive hitter throughout his six-year NPB career. He hit at least 20 home runs five times and recorded a career .851 OPS. It’s worth noting, too, that offense in NPB has generally been down in recent years. That hasn’t slowed Sato.
Sato will strike out, running a 27% K rate over the past two seasons. By comparison, Murakami -- whose strikeout potential raised eyebrows during his posting -- struck out 28.8% of the time in his final two full NPB seasons. That number jumped to 35.4% in MLB for Murakami, though his power and propensity to draw a walk (16.6%) translated well enough for him to hit 35 home runs with an .825 OPS as a rookie. Sato walked at a lesser-but-still-strong 10.3% clip the past two years in NPB.
Sato has proven durable, playing at least 120 games in each year of his career (NPB plays a 143-game regular season). He’s also gained experience on a big stage, helping Hanshin win the 2023 Japan Series and starring in a five-game sample for Samurai Japan in the 2026 World Baseball Classic. He hit three balls with an exit velocity of 100 mph or better in this year’s WBC.
NPB stars coming to MLB has become a staple in the offseason. We could see around four more names follow suit this year, but Sato will be the undoubted headliner. And now, MLB teams and fans alike can start to dream on adding an MVP to their lineup.
