There’s a plausible path where the Red Sox enter 2027 with a rotation that leans heavily left-handed, and that’s why a name from Japan is worth watching.
Garrett Crochet sits at the top if he’s healthy. Payton Tolle and Ranger Suarez are already viewed as rotation locks, and Jake Bennett looks very likely to join them.
That leaves Boston staring at four lefties, which would force the fifth spot to go to a right-hander. Brayan Bello stands out as the best internal answer, while Sonny Gray filled a spot in 2026 before reaching free agency.
That’s where Kaima Taira enters the picture. ESPN’s Kiley McDaniel floated the 26-year-old righty, most recently with the Seibu Lions in Nippon Professional Baseball, as a possible fit for Boston.
"Projected contract/QO: five years, $72.5 million (14.5 AAV), not eligible for QO," McDaniel wrote. "The Red Sox, Nationals and Cubs all covet starters with velocity and big extension, and rivals think they at least have to investigate; I expect lots of interest around $50 million guaranteed and think there will be enough teams motivated to go higher to push to a fifth year. His posting fee for this contract would be $12.75 million, putting the full value at a little over $85 million."
Taira’s production has been eye-catching. In 2026, he posted a 1.36 ERA across 23 appearances and 146 innings for the Lions.
It was only the second time in his pro career that he topped 100 innings in a season. He also threw 150 innings in 2023, when he finished with a 2.40 ERA in 23 outings.
His career has included work both as a starter and as a reliever.
Still, Boston may have reason to pause. Taira’s talent is obvious - he owns a 1.85 career ERA in 351 professional appearances - but the durability question lingers.
He has cleared 100 innings only twice, and the Red Sox have already spent the last few years dealing with injuries that have repeatedly hit their rotation. Paying a premium for a pitcher without a long starter’s track record would be a risky move.
If Boston is deciding where to put its money, the better play might be elsewhere, such as an Adley Rutschman extension, while keeping Bello in line for the No. 5 job. Taira could absolutely remain on the Red Sox radar, but he may not be the first place they should turn.

Red Sox Power Problem Could Force A Painful Offseason Decision
Bostons lack of pop was one of the defining issues of the 2026 season, with the Red Sox finishing near the bottom of the league in home runs and runs scored. That kind of offensive shortage has a way of reshaping an offseason, and it is already pushing the front office toward a familiar but uncomfortable idea: if the lineup needs a true middle-of-the-order force, the answer may have to come from outside the organization.
Craig Breslow does not have an easy path to get there. The clubs supply of young pitching prospects has thinned after recent trades, which limits the kinds of packages Boston can put together, and the most attractive chips left are Wilyer Abreu and Ceddanne Rafaela. Moving either one would be a serious call, especially for a player who can realistically bring 35 to 40 homers a year, because that sort of power is hard to find and even harder to pry loose.

Red Sox Could Solve Two Offseason Needs With One Bold Trade
The Red Sox are still shopping for a right-handed starter and a power bat this offseason, and that has put a familiar name into the center of the conversation. Jarren Duran has been floated as a possible trade chip, and one of the more intriguing fits would send him to Texas, where the Rangers suddenly have a need for outfield help after Evan Carters hip surgery and are also working under payroll pressure.
Nathan Eovaldi is the kind of arm Boston could use to check one box in a hurry, while Duran would give the Rangers a ready-made answer in the outfield. It is the sort of one-move solution that makes sense on paper for both clubs, but for now it remains only a possibility as the Red Sox weigh how aggressively they want to attack two offseason needs at once.

Wilyer Abreu's Rise Leaves Red Sox Facing A Costly Offseason Call
Wilyer Abreus breakout season has given the Red Sox exactly the kind of problem every front office says it wants. After winning his third straight Gold Glove in right field and leading all players in defensive runs saved and outs above average, he also put himself in position for a Louisville Slugger Silver Slugger Award after the best offensive year of his career. For a player who has grown into one of Bostons most valuable regulars on both sides of the ball, the rise has been as steady as it has been sudden.
Now the challenge shifts from appreciation to accounting. Abreu is arbitration eligible for the first time this offseason, and the combination of elite defense and a stronger bat figures to push his price tag up fast. That leaves the Red Sox weighing a player whose value keeps climbing against the reality that his improved profile could also make him more expensive to keep, and more attractive if the club starts listening on trade possibilities.
