The Boston Red Sox need more power in their lineup. Boston finished 26th in MLB in home runs (163) and 20th in slugging percentage in 2026. That won't cut it when you play 81 games a year at Fenway Park, where offense often trumps good pitching.
It also won't get it done in the postseason, where the Red Sox have fallen in the Wild Card Series in consecutive campaigns. This time around, it was clear that Boston didn't have any reliable power hitters outside of Willson Contreras. The good news for the Red Sox is that a 27-year-old slugger is set to hit the free-agent market this offseason. Boston should be monitoring the situation closely.
News that the NPB's Hanshin Tigers have agreed to post Sato is all the more important given MLB's thin free-agent offerings when it comes to power bats. Frankly, there aren't any prime-aged power hitters in MLB hitting the market. Sato should thus have plenty of suitors, and the Red Sox should be one of them.
The Red Sox should enter the sweepstakes for Japanese slugger Teruaki Sato
The Hanshin Tigers have officially accepted Teruaki Sato’s posting request.

Sato's numbers over the past two seasons in NPB have been astronomical. In 2026, he hit .306/.383/.609 with 39 home runs and 106 RBI in 143 games, capturing the Triple Crown. He's got the type of talent that convinced MLB Trade Rumors to rank him second behind only Tarik Skubal on its list of free agents.
Randy Arozarena and Seiya Suzuki are the two most obvious names at the top of the list for Boston, but both players are north of 30. In Sato, Boston would be landing a slugger who is entering his prime years, or is at the start of them already. Given the Red Sox's young core, Sato makes more sense from a timeline perspective.
On the other hand, Sato is far from a perfect player. He's limited defensively and strikes out a lot — not dissimilar from one of last offseason's free-agent slugger prizes, Munetaka Murakami. Of course, the Chicago White Sox took a "gamble" on Murakami (not really — it was only a two-year deal), and that risk paid off well in 2026, with Murakami mashing 35 homers and helping Chicago reach the ALDS.
Sato has primarily played third base and right field in NPB. What the Red Sox could do is slide him over to first and move Contreras into a primary DH role. This would have the secondary consequence of Contreras preserving his body throughout the season, though it would make the Red Sox worse defensively (Contreras is a reliable glove).
