2026 Projections
2026 Fantasy Outlook
Griffin, a first-round pick by the Royals back in 2014, only threw eight big-league innings through the end of his age-26 season before deciding to head overseas in search of more regular opportunities. In 315.2 innings across three seasons for the Yomiuri Giants, he cruised to a 2.57 ERA and 1.03 WHIP, striking out 25.1% of batters while walking just 5.5% and allowing a total of just 18 home runs. His 2025 season was cut short after 78 innings due to a knee injury, but that half-season sample saw him post a dominant 1.62 ERA and 0.95 WHIP while allowing just a single homer. It was enough to convince the Nationals to bring the lefty back to the majors on a one-year, $5.5 million deal, though that dollar value isn't high enough that Griffin is a lock for a rotation spot. If his broad repertoire and pitchability are able to overcome some below-average velocity, he could be a capable innings eater, but a swingman role is also possible. Read Past Outlooks
