Evaluating Teruaki Sato
By Andy Singer
October 20th, 2026
The Yankees' offseason has started early, a fact to which Yankee fans have sadly become accustomed. That means that the hot stove has started before the World Series has even begun. The Yankees began the 2026 season with major holes to fill, and that is even truer today than it was in March. Among the places that the media and fans alike have focused is 3B, where Ryan McMahon produced a truly awful season at the plate and was surprisingly below-average defensively at 3B. If the Yankees are serious about winning in October, it is clear that an upgrade is needed at that position.
Already, the media and many around here at SSTN have keyed in on a fascinating target: Teruaki Sato, a 3B/OF from Japan who lit the NPB ablaze last year at the plate. We know that the Hanshin Tigers have agreed to post Sato, and the hype is building. Many outlets are ranking Sato as one of the two best free agents available in free agency this offseason. The rumors are that the Yankees are very interested in bringing Sato to New York. The fit seems relatively obvious.
With all of that in mind, I thought it would be instructive to take a look at the player in a very objective fashion. Below are four players and their statistics in their final season in NPB before coming stateside to MLB. For all of the players, the season is representative of one of their best in the league at the plate. Let's take a look:
Player A produced the most total value at the plate, showing enormous power. However, Player A also came with concerns. While he posted strong walk rates, his strikeout rate was very high, and his contact and swinging strike rates are the worst among the players who have made the jump to MLB.
Player B was nearly as valuable as Player A, but he got there in a very different way. While he showed pop, it was significantly less than the other players on the board. However, he walked as much as he struck out, and his contact and swinging strike rates were excellent. Player B was very well-rounded, if a bit lacking in the power department relative to the others.
Player C was only marginally less valuable offensively than Players A and B, but the total package under the hood is impressive. Player C had elite power numbers in his last season in NPB, with an elite walk rate and a strikeout rate that nearly matched it, impressive given the power. Even more impressive was the fact that his contact and swinging strike rates were the best of the group when understood in tandem.
Player D took a little bit of everything from above. His total offensive value was elite and his walk rate was solid, but he displayed a very elevated strikeout rate. That wasn't a fluke either, as his contact rate was nearly as poor as Player A (just with less power), but his swinging strike rate was just as poor.
Just on the numbers above, how would you rank these players? I would rank them as follows:
Player C
Player A
Player B
Player D

Ready for the big reveal? Player C is Seiya Suzuki. Player A is Munetaka Murakami. Player B is Kazuma Okamoto. Player D is Teruaki Sato. To some extent, we're splitting hairs, because all of these players had fantastic final seasons in NPB, and the 3 who have come to MLB have had varying degrees of success.
Sato has serious pop, but he doesn't have Murakami's pop. Unfortunately, he also comes with Murakami's significant contact and swinging strike issues, which proved to scare many teams away from Murakami last offseason. Murakami went a long way towards proving the doubters wrong, but he was nowhere near as good after returning from the IL in the 2nd half. Did the injury hamper him, or did the league start to figure him out? The jury is still out. Murakami will clearly have some value for years to come due to his top-of-the-scale, prodigious power. I'm not sure if Sato is in the same category. I also think the numbers above show that he's a step behind Okamoto and Suzuki in other areas of his offensive game. Suzuki is a star at the plate (one I underrated coming out of Japan), but Okamoto is merely fine.
Sato has a skillset that indicates he should be able to play 3B, which gives him a leg up on Murakami, but he has been very error prone aside from his Gold Glove season in 2025. Most reports from Japan indicate that his throwing accuracy is very problematic, so that's something that will need work.
Looking through the game logs I've been able to find, combined with anecdotal reports from Japan, Sato is also a very streaky player. He does a lot of his damage in chunks, and then will have stretches where he looks lost at the plate and in the field. Frankly, the description reminds me a lot of late-career Giancarlo Stanton.
Sato clearly has ability and tools, and he can absolutely play MLB baseball. However, despite the power, raw numbers, and Gold Glove pedigree, there are real concerns in his profile that teams looking to acquire his services need to evaluate. The things Sato does poorly match all of the issues the most recent failed Yankee teams displayed. Sato is young enough to improve these deficiencies, but I have real concerns about his fit on a Yankee team that needs more contact-oriented players who play good defense.
