Foster Griffin’s baseball journey is not done yet. After only seven major league appearances across the 2020 and 2022 seasons with the Royals and Blue Jays and Tommy John surgery that knocked him out of the 2021 season, the former first-round pick took a chance at playing in Japan.
Signed with the Yomiuri Giants of Nippon Professional Baseball in 2023, the left-hander thrived overseas. He went 6-5 with a 2.75 ERA and 1.074 WHIP in 20 starts during his first season in Japan. He then followed that up with a 7-6 record and 2.93 ERA in 24 starts in his second season abroad.
Griffin’s third campaign in Tokyo was his best. He finished 6-1 with a 1.53 ERA and 0.966 WHIP in 17 starts, earning a selection to the NPB Central League All-Star Game. And perhaps most impressively, he allowed only one homer over 89 innings.
Across three seasons in Japan, he went 18-10 with a 2.57 ERA, 1.033 WHIP, 9.1 strikeouts and 2.0 walks per nine innings in 54 games.
That earned him the opportunity to return to the major leagues on a $5.5 million deal, plus incentives, with the Nationals that was made official on Monday. And with that new contract, comes the opportunity to be a starter again, this time in the bigs.
Foster Griffin went to Japan three years ago not because he envisioned it would get him back to the major leagues eventually, but because at the time it was the only place that offered him a chance to be a starting pitcher.
Having bounced back and forth between Triple-A, Kansas City and Toronto while making seven MLB appearances in relief from 2020-22, the left-hander saw an appealing opportunity with the Yomiuri Giants. And once he got the blessing from his then-pregnant wife, he made the move across the Pacific and hoped for the best.
Three highly successful years later, Griffin found himself Tuesday talking about his latest opportunity: Becoming a member of the Nationals’ 2026 rotation after signing a one-year, $5.5 million contract. It’s an opportunity he couldn’t have realistically foreseen when he first left for Japan.
“It’s tough so far to wrap my head around it, to be honest with you,” he said in a Zoom session with reporters. “You hear about some guys going to Japan and coming back and getting deals. But to be honest with you, that was never at the front of my mind when I left. I just wanted to go out there and re-establish myself as a starter. I kind of feel like I got this second chance at baseball in my career, by getting the opportunity to go to Japan.”
In their quest to add some much needed experience to an otherwise young rotation, the Nationals turned their sights to Tokyo. Not for a native Japanese pitcher, but for an American-born, former first round pick who indeed resurrected his career in unexpected fashion.
The Nationals’ one-year contract with Foster Griffin has been finalized, and the 30-year-old left-hander’s signing is now official.
Griffin and the Nats had agreed to terms last Tuesday on a $5.5 million deal, plus incentives, but the contract wasn’t finalized until he passed a physical.
With that matter now resolved, the former first round pick of the Royals turns his sights toward his official return to major leagues after a highly successful, three-year stint pitching in Japan.
Griffin joined the Yomiuri Giants in 2023 after failing to stick in the big leagues and enjoyed immediate success. He went 6-5 with a 2.75 ERA and 1.074 WHIP in 20 starts during his first season abroad, then returned the following season to go 7-6 with a 2.93 ERA in 24 starts.
Griffin’s third season in Tokyo was his best; he went 6-1 with a 1.53 ERA and 0.966 WHIP in 17 starts, earning a selection to the NPB Central League All-Star Game. He allowed only one homer over 89 innings.
The first free agent signed by the Nationals’ new front office is a former first-round pick who went to Japan to resurrect his pitching career.
The Nats are in agreement with left-hander Foster Griffin on a one-year contract that guarantees $5.5 million plus incentives, a source familiar with the terms confirmed. The deal, which was first reported by FanSided.com, is contingent on the 30-year-old passing a physical.
It’s a bit of an unconventional first foray into free agency for new president of baseball operations Paul Toboni, though one that has become increasingly popular among other organizations willing to take a modest financial risk on former big leaguers who parlay success in Asia into major league offers.
Originally the 28th-overall pick of the 2014 Draft by the Royals, Griffin made his major league debut in 2020 and has made seven total big league appearances with Kansas City and Toronto, allowing six earned runs in eight innings. Released by the Blue Jays in November 2022, the 6-foot-3 southpaw then signed with the Yomiuri Giants and turned his career around.
In three seasons pitching in Japan, Griffin went 18-10 with a 2.57 ERA and 1.033 WHIP, working as a starter. The lefty peaked this summer, going 6-1 with a 1.62 ERA, 0.949 WHIP and 77 strikeouts in 78 innings, earning an NPB All-Star selection before being sidelined by a leg injury.
