When the World Series concludes and the offseason officially begins, it’s hard to predict how the market will progress before a presumed lockout at the start of December. The free agent market could especially be slow as owners push for a salary cap and teams may be hesitant to commit to players before they know the economic landscape.
The position-player free agent class doesn’t exactly project particularly strong this offseason despite the abundance of decent players. It may take a very intriguing
player to make teams splurge, but perhaps they are sure to be excited about another Japanese phenom making the jump to the big leagues.
It was just announced this week that Teruaki Sato of the Hanshin Tigers will be posted once the offseason begins, starting a 45-day window for him to seek an MLB opportunity. It’s worth noting that his posting window will freeze during the lockout and resume whenever it ends; otherwise, he would return to Nippon Professional Baseball for another year.
Sato isn’t just any international free agent — he’s coming off a monstrous 2026 season in NPB where he captured the Central League Triple Crown, slashing .306/.383/.609 with 39 home runs and 106 RBIs. That follows a 2025 campaign in which he won Central League MVP honors.
Naturally, MLB contenders across the league are licking their chops. But what about the Colorado Rockies? Should Paul DePodesta and the front office throw their hat into the ring for one of Japan’s most electric power hitters?
The offensive perks
Since debuting in 2021 at 22 with the Tigers, Sato has proven to be one of NPB’s premier sluggers. Over the course of his six seasons, Sato has slashed .271/.337/.514 across 803 games. He has been a dependable and durable player during his career, appearing in at least 120 games each season (NPB plays a 143-game schedule).
What has truly set Sato apart has been his knack for power, with 163 home runs in his career. He has managed at least 20 home runs a year in five seasons, including 79 over the last two seasons combined. The ability to generate bat speed and elite exit velocities was on display in a short five-game sampling with Japan in the World Baseball Classic last March, where he hit three balls with an exit velocity of 100 mph or better.
He’s not just a home run hitter, either, as doubles are his forte as well. In 2026, he had 40 doubles, which would have easily led the Rockies (Troy Johnston had 32), adding to his total of 185 career doubles alongside 25 triples. His career .851 OPS showcases a player who can punish opposing pitchers and provide the type of consistent thump that the Rockies didn’t quite have beyond Hunter Goodman last season.
During a time in which offense has been decreasing in NPB, Sato didn’t slow down and has put himself in line for another Central League MVP. Hitting from the left side, Sato’s offensive profile could benefit greatly from the altitude of Coors Field, but even more from the spacious gaps he would have to play with in the outfield.
What team wouldn’t want to add a second 40-homer bat into the lineup?
Defensive prospects
Sato primarily plays third base with around 262 appearances in the outfield during his career. He has mostly been able to hold his own, even going so far as to win a Golden Glove — the NPB equivalent of a Gold Glove in MLB — at third base in 2025.
Naturally, there is already some versatility built into his game, but there is concern about his long-term fit on the infield at third base.
He owns a career .941 fielding percentage at the hot corner, having committed at least 20 errors in two of the last four seasons. In 2026, he committed 18 errors, but that was after just six in his 2025 Golden Glove season. He has fared better in the outfield, but his overall defensive ability is a concern. Teams may be willing to swallow that because of the bat.
Seems that Sato may have to follow in the footsteps of Munetaka Murakami, who moved over to first base for the Chicago White Sox full time after signing with them. It would certainly make sense to then just let the bat do the talking.
The drawbacks
The defensive aspect of where to play Sato presents a problem for the Rockies, who are sure to focus heavily on improving defensively. Kyle Karros and TJ Rumfield have the corner infield locked down, and the outfield is crowded in the corners.
Sato could be plugged in as the designated hitter, but the Rockies like to use the DH spot as a cycling position, meaning players will constantly cycle through it. There is also the matter of Sato being left-handed, which the Rockies already have enough left-handed bats to utilize. It would also be another instance of blocking an opportunity for right-handed hitter Charlie Condon (No. 2 PuRP), who the Rockies are already having to try to find a spot defensively.
If there’s a red flag in Sato’s profile, it’s his contact consistency. Sato struck out 164 times in 143 games in 2026. High strikeout rates in NPB often translate to elevated swing-and-miss rates against elite MLB velocity and breaking pitches. Rockies fans know all too well how high-K profiles can get exposed when adjusting to MLB pitching while dealing with the “Coors Field Hangover” effect on the road. Looking again to Murakami with the White Sox, he saw a 28.8% strikeout rate over his last two NPB seasons balloon to 35.4% in his first MLB season. His ability to draw walks still translated, but can Sato do the same?
Then there is the monetary aspect. Because Sato is over the age of 25, there will be no restrictions on the money that can be offered to him. On top of a multi-year, multi-million-dollar contract, the acquiring team must pay a posting fee to the Tigers based on the contract’s total value. The Rockies have a lot of holes to fill, and unfortunately, spending big on Sato would come at the cost of a lot of other areas where the money could go. Having to compete with the financial might of many of the teams in the league hasn’t exactly worked out for the boys in purple in the past.
Should the Rockies pursue Sato?
Absolutely, the Rockies should pursue Sato, at least conceptually.
A young left-handed slugger at Coors Field is always a sight to behold. If the Rockies want to accelerate their rebuilding timeline and show fans a commitment to competing, making a splash in the international market for a marquee power hitter like Teruaki Sato would be a massive statement move.
However, the financial uncertainty for the club, the commitment to internal development as much as possible, and the massive need for pitching make Sato a bit of a long shot. I’m sure the front office will do their due diligence and at least check in with Sato and hopefully continue building a reputation with the Japanese market (which was a bonus of signing Tomoyuki Sugano).
Wherever Sato ends up, it will be interesting to see what he can do in MLB after the splendid seasons of Murakami and Kazuma Okamoto this year.
In the meantime, the Rockies may want to take a closer look at the other Japanese stars looking to pitch in MLB in 2027.
