Signs $5.5M deal with Nationals The Nationals signed Griffin to a one-year, $5.5 million contract Tuesday, Robert Murray of FanSided.com reports.

Impact 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.

Poised for return to majors Griffin is expected to seek a major-league contract following a three-year stint with the Yomiuri Giants of Nippon Professional Baseball, Jon Heyman of the New York Post reports.

Impact 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.

Let go by Toronto Griffin was released by the Blue Jays on Tuesday, Shi Davidi of Sportsnet.ca reports.

Impact Griffin is expected to continue his professional career overseas in Japan, leading the Blue Jays to release him. The 27-year-old appeared in only six MLB games in 2022 but had a 2.10 ERA across 51.1 innings at the Triple-A level.

JUNE 26, 2022 • ROTOWIRE

Recalled by Kansas City Griffin was recalled from Triple-A Omaha on Monday.

Impact Griffin made a pair of relief appearances for the Royals in mid-May, and he allowed four runs in two innings. The southpaw has been much more effective in Omaha, posting a 1.83 ERA and 0.94 WHIP in 19.2 innings over 13 relief appearances. While his first three major-league appearances have come out of the bullpen, Griffin has experience working as a starter in past minor-league seasons. The Royals haven't announced who will fill Zack Greinke's (elbow) spot in the rotation after he was placed on the 15-day injured list Monday, but it's possible that Griffin will be in the mix to take on a starting role.

Optioned to Triple-A Omaha Griffin was optioned to Triple-A Omaha on Sunday.

Impact Griffin made two appearances during his stay in the majors. He's allowed four runs, three hits and two walks across two innings, with all of the damage coming in his latter outing. The left-hander was optioned to make room for Ronald Bolanos (undisclosed) to be activated from the injured list.

MAY 22, 2022 • ROTOWIRE

Contract selected by Kansas City Griffin had his contract selected by the Royals on Friday.

Impact Griffin was unable to crack the Opening Day roster but will now receive his first big-league chance in 2022. The left-hander appeared in 13 games for Triple-A Omaha this season and has a 1.83 ERA, 0.94 WHIP and 23:4 K:BB across 19.2 innings.

MAY 20, 2022 • ROTOWIRE

Dropped from 40-man roster The Royals designated Griffin (elbow) for assignment Monday.

Impact The transaction clears a spot on the 40-man roster for outfielder Michael Taylor, who signed a one-year, $1.75 million contract with the Royals on Monday. A 2014 first-round pick, Griffin reached the big leagues for the first time in 2020, appearing in one game and tossing 1.2 scoreless innings out of the bullpen. He suffered a forearm strain in that outing and subsequently underwent Tommy John surgery. Since Griffin isn't a major prospect and won't be back to full health until the spring of 2022, the Royals deemed him an expendable piece on the roster.
