Foster Griffin Looking To Return To MLB In Free Agency

By Mark Polishuk | October 19, 2025 at 11:05pm CDT

Left-hander Foster Griffin’s Major League resume consists of seven games and eight innings of 6.75 ERA ball with the Royals and Blue Jays during the 2020 and 2022 seasons.  Looking for a change of scenery, Griffin signed with the Yomiuri Giants prior to the 2023 season, and the New York Post’s Jon Heyman reports that the 30-year-old southpaw is now looking to return to North American baseball after three successful years in Japan.

While Griffin hadn’t shown much in his few cups of coffee in the majors, he posted a 2.10 ERA, 27.1% strikeout rate, and 7.1% walk rate over 51 1/3 relief innings with the Royals’ and Blue Jays’ Triple-A affiliates in 2022.  Griffin had started almost all of his pro games prior to the 2022 campaign, but the move to full-time bullpen work seemed to unlock something for Griffin after some inconsistent results as a starter.

Injuries also played a role in Griffin’s career. Griffin’s tore his UCL in his very first big league game in 2020, resulting in a Tommy John procedure and a long stint on the shelf.  His good numbers in 2022 seemed to indicate that he’d covered well from his surgery, but his decision to head overseas may have been inspired by a desire to get another crack at starting.

The decision to bet on himself looks to have paid off.  Griffin had a 2.57 ERA, 25.07% strikeout rate, and 5.52% walk rate across 315 2/3 innings and 54 games with the Giants.  His debut year in 2023 was so impressive that the Giants inked him to a two-year extension, which is notable since foreign-born players in NPB are usually given just one-year deals.  Griffin’s work helped the Giants reach the postseason in each of the last two NPB seasons.

FanSided’s Robert Murray mentioned back in July that MLB teams had taken notice of Griffin’s numbers in Japan, so with his contract with the Giants now completed, it isn’t surprising that Griffin is aiming to get back to the bigs.  Merrill Kelly or Erick Fedde are among the recent example of pitchers who reinvented themselves in foreign leagues and returned to land multi-year free agent commitments, and the same could be true for Griffin despite his thin track record in the Show.  Teams are forever looking to add starting pitching, and Griffin is an interesting lower-cost option for any club in need of rotation help.

      Dodgers night be interested in him for the bullpen. Low walks, decent strikeouts, and likely not expensive.

      They have full time scouts in happen, so we’ll see what they think of him this off-season.

          A possibly low cost effective arm?

          Yeah that’s everyone.

          Why don’t you name a list of expressive free agents the dodgers didn’t sign the last few years.

          Why don’t the Dodgers purchase NPB and turn the whole league into a farm team?

          …..or better yet, why don’t the Dodgers just move to the NPB and defer their yen elsewhere?

          That’s like asking why don’t the Dodgers just buy the Pirates for Paul Skenes and a few of their other players. And the answer is the same.

          Both the Pirates and NPB have many bad players. And the Dodgers just want the good ones.

    Baltimore or St Louis would be a good fit.

      This is 100% the type of signing Mozeliak would’ve wanted to make. Got Mikolas from over there and tried to sign Fedde when he came over. Will be interesting to see how similar Bloom is and if he follows the same path

    The Padres are known for signing pitchers out of NPB and KBO. Martinez, Suarez, Matsui, Hart, and Pierce Johnson to name a few. Will Griffin be the next?

    His fastball only averages 90.8 MPH but his success especially since he came back up from the NPB minor league coincided with the addition of a sweeper which saw his strikeout rates improve considerably.

    Hopefully Cody Ponce decides to come back from the KBO that dude might actually get a decent contract he had eye popping numbers this year.

    He would pencil in well at the back of the Red Sox rotation.
