The Boston Red Sox have been busy this offseason, kicking the tires on some big-name infielders like Alex Bregman and Ketel Marte. But while those headline-grabbing names dominate the rumor mill, there’s another intriguing option quietly gaining steam: Japanese slugger Kazuma Okamoto.
Okamoto, a 29-year-old power bat from Nippon Professional Baseball (NPB), is drawing serious interest from multiple MLB clubs - including the Red Sox, Pirates, and Blue Jays. And there’s good reason for that. This guy isn’t just a flash in the pan overseas; he’s a proven 30-homer threat with a swing tailor-made for Major League ballparks - especially one like Fenway Park.
Let’s break this down.
The Red Sox are looking to inject some right-handed power into their lineup, and Okamoto checks that box emphatically. He’s built his reputation in NPB as a consistent slugger, with the kind of raw pop that translates well across the Pacific.
Scouts love his ability to drive the ball in the air to his pull side - and when your home park features the Green Monster in left field, that’s more than just a nice fit. That’s a potential game-changer.
Even in the face of MLB’s higher average velocity, Okamoto’s swing and bat speed are considered MLB-ready. Unlike some other Japanese hitters who’ve struggled to adjust to big-league heat, Okamoto is seen as someone who can handle velocity and still get his swing off with authority.
Now, there’s the question of fit - especially if Boston does land Bregman. Both players are natural third basemen, but Okamoto brings versatility to the table.
He’s logged time at first base and could also slide into designated hitter duties if needed, especially with Masataka Yoshida’s role still somewhat fluid. That kind of flexibility gives Boston options, and in today’s game, roster versatility is gold.
The Red Sox reportedly missed out on Pete Alonso earlier this offseason, which only intensifies their need for a power-hitting corner infielder. Re-signing Bregman would help stabilize the hot corner, but it wouldn't fully address the need for more thump from the right side. That’s where Okamoto could step in - not as a consolation prize, but as a legitimate impact bat who could thrive in the American League.
According to reports, Okamoto is expected to command a deal in the ballpark of four years and $60 million-plus. That’s a significant investment, but for a team like Boston, which is looking to re-establish itself as a postseason contender, it’s a move that could pay dividends on both sides of the ball.
Okamoto brings more than just power. He’s a disciplined hitter with a mature approach at the plate, and he’s been a consistent performer on one of Japan’s biggest stages. There’s always some uncertainty when it comes to international signings, but Okamoto’s skill set - power, plate discipline, positional flexibility - makes him one of the more MLB-ready bats to come out of Japan in recent years.
The Red Sox haven’t made their big splash yet this winter, but keep an eye on this one. Okamoto may not be the most talked-about name on the market, but he might just be the one who fits best in Boston.
