The Washington Nationals are dipping back into the international talent pool. They’ve reportedly landed left-hander Foster Griffin on a one-year, $5.5 million deal, with up to $1 million in incentives.
It’s a low-velocity, high-pitchability bet on a 30-year-old who reinvented himself in Japan. Now he arrives in D.C. with a shot to stabilize a fragile rotation—and maybe even become a midseason trade chip if things break right.
Nationals Take a Calculated Shot on Foster Griffin
The Nationals are still deep in a rebuilding phase. That reality is written all over this agreement.
A one-year contract in this price range is the classic “prove-it” deal. There’s modest downside for the club and a huge opportunity for the player.
For Washington, the appeal is obvious. Rotation innings are up for grabs, and the team needs someone who can take the ball every fifth day and buy time for its younger arms.
Griffin, with his recent track record in Japan, fits that template.
From MLB Fringe to NPB Standout
Griffin’s story is pretty familiar in modern baseball. He was a former prospect whose career plateaued in MLB, then resurfaced overseas as a more polished, complete pitcher.
He made just seven big league appearances with the Kansas City Royals and Toronto Blue Jays between 2020 and 2022. He never really got a consistent shot to stick in a major league rotation.
Everything changed when he signed with the Yomiuri Giants in Japan. Over three seasons, Griffin carved out a reputation as a dependable starter, posting a 2.57 ERA across 315 2/3 innings.
That’s not a small sample. That’s sustained excellence in a competitive league that’s becoming a springboard back to MLB jobs.
A Dominant 2025 in Japan Despite Injury
The 2025 campaign showed why the Nationals were willing to invest. A leg injury limited Griffin to just 78 innings, but those frames were elite by any standard.
He finished the year with a 1.62 ERA, supported by strong strikeout and groundball numbers. That combination—missing bats and keeping the ball on the ground—is exactly what analytically inclined front offices want, even if the radar gun doesn’t light up.
Soft-Tossing Lefty With a Deep Arsenal
Griffin isn’t going to wow anyone with pure velocity. His fastball sits in the low 90s, a tick below today’s power-pitcher prototype.
But his value lies in the breadth and command of his arsenal, not just radar readings. Here’s what he reportedly throws:
This kind of kitchen-sink repertoire is tailor-made for a pitcher who has to win with sequencing, deception, and precision instead of pure stuff. If his command translates back to MLB, he’s got the tools to turn lineups over a few times.
How Griffin Fits Into the Nationals’ Rotation Puzzle
Washington’s current rotation mix reflects a franchise still searching for long-term answers. Names like MacKenzie Gore, Cade Cavalli, and Josiah Gray carry upside, but each comes with health questions, inconsistency, or both.
Beyond that core, the depth chart is full of back-end options and swingmen—useful arms, but not ones you’d confidently pencil in for 30 starts. That’s where Griffin enters the picture.
He doesn’t block top prospects for the long haul. Yet he offers a higher floor than many in-house options.
Stability Now, Trade Chip Later?
From a roster-building standpoint, Griffin is exactly the kind of short-term starter a rebuilding club should target. If he pitches to the level he showed with Yomiuri, something close to a mid-rotation arm, his value to Washington comes in two forms:
If the Nationals find themselves out of contention by midseason, a productive Griffin could be flipped for prospects. If he struggles, the financial hit is minimal, and the team can just pivot to other options.
A Low-Risk, High-Opportunity Move for Both Sides
At one year and $5.5 million plus incentives, Washington isn’t taking much of a gamble. The club avoids tying up long-term money and doesn’t block any core prospects.
For Griffin, it’s a real shot to show that what worked for him in Japan can translate to a full MLB rotation spot. He’s got a lot to prove, and he knows it.
Looking at the bigger picture, this move highlights something interesting: smart rebuilding teams are scouring NPB and KBO for undervalued arms who can steady a pitching staff and maybe become trade chips down the road.
Foster Griffin is now the Nationals’ latest experiment with that approach—a crafty lefty, not a flamethrower, hoping this second chance sticks. Who knows? Maybe it will.
