Fantasy Impact: Griffin has appeared in just seven big-league games in his career, last appearing in the 2022 season before spending the last three seasons pitching in Japan. He posted a tidy 1.62 ERA across 14 appearances (13 starts) and 78 innings pitched in the 2025 campaign, helping pave his way back to the big leagues.

The Nationals acquired RHP Luis Perales from the Red Sox for LHP Jake Bennett.

Fantasy Impact: It is a trade of pitching prospects between Boston and Washington. Perales holds high upside with his velocity and movement on the mound. He'll have a chance to work his way into a role with a rebuilding Nationals pitching staff.
