The Nationals are going to sign left-hander Foster Griffin, reports Robert Murray of FanSided. It’ll be a one-year, $5.5MM contract with another $1MM in incentives for the Excel Sports Management client. The Nats have 40-man vacancies and won’t need to make a corresponding move.
Griffin, now 30, got some brief major league action a few years ago. He made seven appearances, split between the Royals and Blue Jays, over the 2020 and 2022 seasons. He has spent the past three years in Japan, pitching for the Yomiuri Giants of Nippon Professional Baseball, with great success.
He tossed 315 2/3 innings over those three campaigns, allowing 2.57 earned runs per nine. He struck out 25.1% of batters faced, only gave out walks to 5.1% of opponents and kept about half of balls in play on the ground. In 2025, a leg injury limited him to just 78 innings but it was his best season in terms of run prevention. He posted a 1.62 ERA with a 25.1% strikeout rate, 5.9% walk rate and 48.9% grounder rate.
Despite the solid numbers, there are some questions about whether how his stuff will translate to North American ball. Griffin’s fastball only sits in the low 90s, fairly soft by modern standards. He succeeds with a deep arsenal which also includes a slider, cutter, changeup, splitter, curveball and two-seamer.
It has been a relatively busy winter in terms of guys returning to North America after stints overseas. Cody Ponce got $30MM over three years from the Blue Jays. The White Sox gave Anthony Kay $12MM over two years. Drew Anderson got one year and $7MM from the Tigers and Ryan Weiss got one year and $2.6MM from the Astros. All pitchers have had some success in Japan or South Korea but the price differences are likely down to the stuff. Ponce is 6’6″ and 255 pounds with a fastball that averages in the upper 90s with a splitter/kick change that is considered a plus pitch. Griffin isn’t tiny, as he’s listed at 6’3″ and 225 lbs., but his crafty, soft-tossing lefty profile is obviously different than that of Ponce.
More to come.
