Mets May Have Found A Lefty Bullpen Option In An Unusual Place

The New York Mets could bolster their bullpen with a savvy signing of a former Red Sox pitcher who's found his groove in Japan.

David Stearns has never seemed shy about chasing a certain kind of free agent: the pitcher who goes overseas, finds something new, and comes back looking like a different arm. Darwinzon Hernandez fits that mold, and he may be the next name to surface as a possible Mets target.

Hernandez is reportedly eyeing a return to the majors after a strong run in Japan. The left-hander turns 30 in December and has not pitched in American affiliated ball since 2023, when he appeared with the Baltimore Orioles.

Before that, he spent parts of his career with the Boston Red Sox, where he worked in 91 games and posted a 5.06 ERA. The biggest issue in that stretch was command, with a 7.7 BB/9 rate.

That problem looked a lot different in Japan. Hernandez put up a 1.48 ERA there this past year, along with 3.4 BB/9 and 11 K/9. Across 131.2 innings in NPB, he has been excellent overall, recording a 2.48 ERA with 2.9 BB/9 and 11.5 K/9.

The Mets’ interest would make sense on several levels. They need a left-handed reliever, but they also would not want to box themselves into a deal that keeps them from going after a bigger name later.

Hernandez still has one minor league option left, which adds to the appeal if he returns on a major league contract. That situation is similar to Jared Young and Brandon Waddell before the 2025 season, when both came back from the KBO and landed major league deals.

After the long look the Mets gave Jefry Yan, there is not much reason for them to avoid this type of move beyond the possibility that Hernandez asks for a little more money. Players coming back from overseas with success usually do not get paid like a typical free agent with those numbers, and incentives often play a big role in deals, especially when the contract runs longer than one year.

The market for Hernandez should be broad, but the price tag should still leave room for other business. Foster Griffin signed for $5.5 million last offseason as a left-handed starter after posting a 2.57 ERA in Japan. Hernandez, by comparison, is probably looking at no more than $2.5 million, and that may even be generous.

The reason he is drawing attention is simple: the control issues that once held him back were addressed overseas. If that version of Hernandez is real, the Mets look like a team that should be watching closely.

Mets Tried To Sneak Through Depth And Got Burned Fast

The Mets have been leaning on split contracts as a way to stockpile depth without tying up a full 40-man spot, but the approach can cut both ways. Christian Cairo was signed to a major league split deal, only to be waived soon after, and the Dodgers jumped in to claim him, a reminder that even the most back-end roster moves can draw interest when a player is exposed.

Kyren Paris, meanwhile, made it through waivers and stayed in the organization, which is the kind of outcome the Mets are hoping for when they take this route. The pattern underscores the balancing act in front of the front office: trying to preserve useful minor league depth while knowing another club can swoop in at any moment if the player looks worth a look.

Mets Coach Connection Could Create An Unexpected Third Base Option

Si-hwan Roh is one of the more interesting names to surface this offseason from Korea, and the Mets have at least one built-in tie to the conversation. The KBO infielder has been posted for MLB teams, and his history with newly hired co-hitting coach Johnny Washington gives New York a familiar connection as it weighs whether there is any fit.

The appeal is easy to see, even if the path is not. Roh has been mentioned by some analysts as a possible short-term answer at third base, but his offensive profile and positional overlap with current Mets players make any move far from straightforward. MLB.com has also linked him to several other clubs, so if the Mets are serious, they may have competition as they sort out whether the connection is enough to matter. [Read more 🡒]

Carson Benges Rookie Snub Cost The Mets More Than An Award

Sal Stewarts win in the National League Rookie of the Year race left Carson Benge and the Mets on the outside looking in, and the result carried more than just the usual award-day sting. New Yorks outfielder finished second after voters leaned toward Stewarts traditional counting stats, with home runs and RBIs carrying the kind of weight that often still wins out over the newer metrics that favored Benge.

For the Mets, the miss also came with a practical cost. The Prospect Promotion Incentive program gives clubs an extra draft pick when a promoted rookie wins Rookie of the Year, and that avenue was there for New York if Benge had taken the award. Instead, the Mets are left with the reminder that a close vote can ripple beyond the trophy itself, especially when a young players case is built more on underlying value than on the numbers that tend to grab attention first.
