Shintaro Fujinami to play winter ball, hoping for MLB opportunity

Right-hander Shintaro Fujinami is planning to play in the Puerto Rican Winter League this offseason as he looks to demonstrate his health for interested clubs, he revealed in an interview with Japanese news outlet Sponichi. He hopes to continue playing in the United States for the 2025 season.

Fujinami’s one-year, $3.35M deal with the Mets for the 2024 season was derailed by injuries. The hard-throwing 30-year-old (31 in April) was expected to have a place in New York’s bullpen but landed on the injured list in spring training due to shoulder troubles and never wound up pitching in the majors. 

He pitched four scoreless rehab innings between Rookie ball, Class-A and Double-A but was hit hard in 32 frames with the Mets’ Triple-A club. In those 32 frames, he yielded a 6.68 ERA and walked just over 22% of his opponents. Fujinami still sat at a hearty 97.3 mph with his heater and fanned 25.7% of his opponents, but that velocity was down from the prior season and his command was a disaster even relative to his own shaky standards.

Many Mets fans raised an eyebrow at the time of the Fujinami signing. A big league deal for a reliever coming off a combined 7.18 ERA in 79 innings between the A’s and Orioles in 2023 indeed looked curious absent more context. But that ghastly earned run average was skewed by a woeful run of four starts with the A’s to begin his big league career. Fujinami pitched just 15 innings in Oakland’s rotation but yielded 24 runs on 19 hits and 12 walks. He was dropped to the bullpen and, after a rough start in that role as well, found his groove.

Over his final 51 1/3 innings of the 2023 campaign, Fujinami posted a far more palatable 4.21 ERA. That’s still hardly an eye-catching mark, but that earned run average was accompanied by a 25.5% strikeout rate and 9.9% walk rate — vast improvements from his earlier work. He also averaged a blazing 99.2 mph on his heater during that stretch and coupled that with a sharp 12.7% swinging-strike rate. Fujinami was showing an ability to miss bats both off the plate and in the zone and, at times, looking flat-out dominant (as can be seen in GIF form, courtesy of the indispensable Rob Friedman). A modest one-year deal for a then 29-year-old righty who was once a top pick and prospect alongside Shohei Ohtani in NPB seemed perfectly sensible, particularly for a deep-pocketed club like the Mets.

This time around, a big league deal seems less likely (though not impossible, depending how he looks in Puerto Rico). He’ll be showcasing his health in hopes of generating interest among big league clubs. If he looks healthy and regains some of the roughly two miles per hour he lost off his heater in the wake of that shoulder injury with the Mets, he could land an invite to spring training next year and compete for a job in a big league bullpen. MLB clubs are constantly drawn to power arms of this nature, so a non-guaranteed deal should be there if Fujinami is healthy and shows some semblance of improved command.
