Ken Waldichuk

The Washington Nationals claimed left-hander Ken Waldichuk off waivers from the Tampa Bay Rays on Thursday and designated right-hander George Soriano for assignment in a corresponding move, according to president of baseball operations Paul Toboni. Waldichuk, 28, has not pitched in the big leagues since 2023. The former fifth-round selection by the New York Yankees in 2019 out of Saint Mary's College went 6-11 with a 5.28 ERA (5.10 FIP) and 1.49 WHIP with 165 strikeouts and 81 walks in his two seasons with the Athletics in 2022 and 2023. Waldichuk made only seven starts in 2022 and then had a 5.36 ERA and 1.56 WHIP in 35 outings (22 starts) over 141 frames in 2023. He has now been with four different teams this offseason. In his first year back from Tommy John surgery in 2025, Waldichuk struggled to an 8.65 ERA and 2.06 WHIP in 51 innings at Triple-A Las Vegas.
