Teruaki Sato was born in Nishinomiya, a city of roughly 500,000 in Japan’s Hyogo prefecture. Koshien Stadium, home of the Hanshin Tigers, is also located in Nishinomiya, and as such, Sato grew up a Tigers fan. Although he played baseball as a boy, he lost much of his passion for it as his teenage years began and was more interested in soccer. He attended Incheon Gakuin Senior High School and only tried out and made their baseball team because of the insistence of a friend.
Sato received very little
local or national attention as an undersized, scrawny infielder on a team that did not make koshien any of the three years he attended. While he could not control the fortunes of his team, he was able to improve himself, and thanks to weight training, had transformed into a much stronger infielder by his senior year, hitting 15 home runs that year as opposed to 5 in his prior two.
Because Incheon Gakuin Senior High School was such a relatively unknown school and his coaches there were not in contact with professional scouts, his performance in high school did not attract NPB scouts. Sato was noticed by Hidemasa Tanaka, the baseball head coach at Kindai University, however. He convinced Sato to enroll at the school and the outfielder/infielder quickly established himself as the best player on the team over the course of the next four years.
Sato registered for the 2020 NPB Draft and ended up being selected by the Fukuoka SoftBank Hawks, Orix Buffaloes, Yomiuri Giants and Hanshin Tigers with their first-round picks. The Tigers won the lottery for his rights, and just like that, the boy from Nishinomiya was a member of his hometown team.
The rookie outfielder had a strong spring training and made the Tigers in 2021, but his production took a hit as regular season progressed. While he showed a ton of power, he did not take many walks and struck out at a staggeringly high rate. In late August, mired in a deep slump, he was sent down to the Tigers’ ni-gun minor league team for a few weeks. After returning to the majors in late September, he continued struggling and eventually set the NPB record for most consecutive plate appearances by a position player without logging a hit, coming to the plate 54 times between late August and late September without a hit. Ultimately, Sato appeared in 126 games for Hanshin in 2021 and hit .238/.284/.466 with a team-leading 24 home runs, 6 stolen bases, 5.5% walk rate, and a staggering 38.0% strikeout rate.
In 2022, the 23-year-old Sato became the youngest player in Hanshin Tigers history to be penciled into the opening day line-up as the team’s clean-up hitter. While he hit fewer home runs than he did in his rookie season, Sato’s sophomore season was an improvement virtually in every other regard. He appeared in all 143 games for the Tigers and hit .264/.328/.470 with 35 doubles, 8 triples, 20 home runs, 11 stolen bases, and drew 51 walks to 137 strikeouts. Additionally, he appeared in more games as a third baseman than he did in 2021, increasing his utility to manager Akihiro Yano. In 2023, newly hired manager Akinobu Okada liked the idea of having Sato play third base that he made the move permanent. The 24-year-old did not miss a beat and appeared in 132 games for the Tigers, hitting .263/.339/.498 with 30 doubles, 6 triples, 24 home runs, 7 stolen bases, and 54 walks to 139 strikeouts. That winter, he would spent time in the U.S., training at the Driveline Baseball facility outside of Seattle to work on optimizing his swing and biomechanics to help cut down on swings-and-misses and poor contact while retaining his power.
The 2024 season began very poorly for Sato, as he got out of the gate slowly and found himself mired in a slump for most of April. He recovered by the end of the month, but his 2024 season would end up a disappointment for the 25-year-old infielder, though over the course of the season, he did make some history by becoming the first Hanshin player since Akinobu Okada did it in the early 1980s to log 100 hits and slug double-digit home runs in his first four seasons. He would appear in 120 games for the Tigers and hit .268/.327/.439 with 21 doubles, 4 triples, 16 home runs, and 36 walks to 133 strikeouts.
Sato came into the 2025 season the same player as he had been in the prior four, but for whatever reason, everything began clicking for him. He appeared in 139 games for the Tigers and hit .277/.345/.579 with 34 doubles, 4 triples, 40 home runs, 10 stolen bases, and 57 walks to 163 strikeouts, establishing career-bests in virtually every offensive category. His 40 home runs were most in the Central League by a wide margin—Shota Morishita hit 23 and ended the season in second place—and enough of his other stats were near or at the top of the league leaders that the third baseman was voted NPB Central League Most Valuable Player in a landslide.
Over that winter, his contract negotiations with Hanshin were difficult, as the discussion of him eventually being posted to a Major League Team came up numerous times, but Sato and the Tigers ended up agreeing to terms just two days before spring training began. He would not remain in camp for very long, as he left along with the rest of Team Samurai Japan to play in the 2026 World Baseball Classic. Playing right field in two games, DH in two games, and third base in one, Sato appeared in 5 games during the competition and went 3-10 for the defending champions in their games against Taiwan, South Korea, Australia, the Czech Republic, and Venezuela, belting three doubles, drawing a walk, and striking out twice.
In 2026, the 27-year-old slugger appeared in 143 games for the Tigers and hit .306/.383/.609 with 40 doubles, 3 triples, 39 home runs, 8 stolen bases, and 68 walks to 164 strikeouts, his 40 doubles and 39 homers both leading the Central League as well as his .306 batting average and .609 slugging percentage- his .383 OBP was merely second in the league, behind Shota Morishita’s .394. With a league-leading 106 RBI, Sato won the Central League Triple Crown, becoming the becoming the ninth player overall in NPB history to achieve the feat, the first player to do so since Munetaka Murakami hit .318 with 56 home runs and 134 RBI in 2022, and the first Hanshin Tigers player since Randy Bass hit .389 with 47 home runs and 109 RBI in 1986.
The left-handed Sato stands square at the plate, holding his hands high at the eyes and angling his bat behind his head at 10:00. He swings with a slight leg lift and has a long-levered, angular bat path that is designed to lift the ball. Sato is a better low ball hitter than high ball hitter, able to really put a jolt into balls that he is able to fully extend and unload on; in 2025, NPB+ Hawk-Eye tracking data measured his max exit velocity at 116.0 MPH, during the 2026 WBC he was measured as high as 108.6 MPH. During the 2026 regular season, the slugger logged multiple batted ball events with recorded exit velocities over 110 MPH.
Like many modern sluggers, much of Sato’s home run power comes from an optimization of his batted ball spray. The slugger pulled the ball at a 39.8% rate in 2026, went up-the-middle at a 40.7% rate, and went to the opposite field at a 19.5% rate, with a minor 5% increase in his up-the-middle percentage and a 5% decrease in his pull percentage as compared to his 2025 season. He posted a 12.4% line drive rate, 32.1% groundball rate, and 55.5% flyball rate, with slight positive increases in his line drive and flyball rates and a slight decrease in his groundball rate as compared to 2025. His 20.8% pulled flyball rate put him in the 80th percentile in the NPB in 2026
With the power and plethora of home runs comes an aggressive approach that raises red flags with most scouts and evaluators. Over the course of his career, Sato has posted a cumulative 8.8% BB% and a 27.4% K%; over the last two seasons, he posted walk rates of 9.5% and 11.1%, respectively, along with strikeout rates of 27.3% and 26.7%.
He posted a slightly above-average 52.5% Swing% and a slightly below-average 66.3% Contact% in 2026, meaning that he swung a bit more than the MLB average and made a bit less contact than what is considered average in Major League Baseball. Against pitches in zone, Sato had a 79.6 Swing% with a 78.1 Contact%, and against pitches outside of the zone, he had a 36.4 Swing% with a 51.0 Contact%. His in-zone numbers both are once again slightly below-average as compared to the MLB average, while his out-of-zone swing rate was slightly below-average and his out-of-zone contact numbers well below average. His Swing% rate against pitches in the heart of the zone, in the shadow of the zone, chase pitches, and waste pitches are all high, but his rate against pitches in the shadow of the zone is considerably higher than MLB average, as opposed to the others, which are only marginally higher. Interestingly, this is not actually a weakness leading to a preponderance of his whiffs; Sato’s Contact% against such pitches is higher than average and his Swing/Run Value is positive against pitches in the shadow of the zone.
The slugger saw a wide variety of pitches in his 614 plate appearances in 2026, facing four-seam fastballs 37.7% of the time, splitters/forkballs 18.3% of the time, sliders 17% of the time, cutters 11.9% of the time, changeups 5.6% of the time, two-seam fastballs/sinkers 5.2% of the time, and curveballs 4.1% of the time. The left-hander posted positive run values against every pitch type he faced, with the highest weighted runs above average per 100 coming from two-seam fastballs/sinkers, changeups, and cutters, while his lowest weighted runs above average per 100 came from curveballs, splitters, four-seam fastballs, and sliders. Of note, the average fastball velocity that Sato faced in 2026 was 147.9 KM, which converts to 91.9 MPH.
Defensively, the third baseman has improved over the years, but still leaves a lot to be desired. Having experience in the infield as well as in the outfield, Sato was initially made a third baseman by Hanshin manager Akinobu Okada because he showed good footwork, arm strength, picking, and receiving in the infield. The transition was far from smooth, as he committed 20 errors in his first year as a full-time third baseman in 2023 and 29 in his second full year there. After being sent down to Hanshin’s ni-gun team for a brief period early in the 2024 season to work on his defense, Sato worked extensively with infield coach Shuta Tanaka that winter to improve his defense. The work he put in paid dividends in 2025, as he committed just 6 errors in 2025, but his yips returned in 2026, posting 18 errors.
Because he has a strong arm and possesses some athleticism, Sato can also play a corner outfield position as well, occasionally being penciled in as one by manager Kyuji Fujikawa over the past two seasons.
