The Nationals signed Griffin to a one-year, $5.5 million contract Tuesday, Robert Murray of FanSided.com reports.
EDGE Analysis
He can earn an additional $1 million in incentives. Griffin logged eight innings in the majors with the Royals between the 2020 and 2022 seasons before spending the last three seasons pitching for the Yomiuri Giants of Nippon Professional Baseball in Japan, where he collected a 2.57 ERA, 1.03 WHIP, 25.1 percent strikeout rate and 5.5 percent walk rate over 315.2 innings. The left-hander should open the 2026 campaign in the Nationals' rotation.

Griffin is expected to seek a major-league contract following a three-year stint with the Yomiuri Giants of Japan's Nippon Professional Baseball, Jon Heyman of the New York Post reports.
EDGE Analysis
Griffin put up a 2.57 ERA, 1.03 WHIP, 25.1 percent strikeout rate and 5.5 percent walk rate over 315.2 innings during his three seasons with the Giants. The 30-year-old southpaw saw brief action in the majors with the Royals in 2020 and 2022, allowing seven runs (six earned) with a 5:5 K:BB over eight innings. Griffin appears to have figured something out overseas and should have a chance to land a major-league contract this offseason.

Griffin was designated for assignment by the Royals on Monday.
EDGE Analysis
Griffin was called up from Triple-A Omaha on Sunday, but he will now either get claimed by another team or return to Omaha after he was DFA'd Monday. The 26-year-old has struggled in his limited appearances in the big leagues this season, compiling a 12.46 ERA and 2.31 WHIP with two punchouts over 4.1 innings. Griffin has produced a far more effective 1.93 ERA and 0.89 WHIP with 32 strikeouts over 28 frames with Omaha this year.

The Royals recalled Griffin from Triple-A Omaha on Sunday.
EDGE Analysis
Though he'll be joining the 26-man active roster as a replacement for Jonathan Heasley (shoulder) -- who was placed on the 15-day injured list -- Griffin won't be replacing Heasley in the rotation. Griffin has worked no more than 2.1 innings in any of his 25 appearances between the majors and Triple-A this season.
