Of the eight teams Tarik Skubal faced more than once in the 2025 regular season, his worst numbers (by a considerable margin) are against the Mariners — a 5.91 ERA in two starts. He first pitched against them on April 2 and gave up three runs in 5 2/3 innings, including a solo homer to rookie Dylan Moore. He surrendered three walks, a rarity for him.
When he saw them again on July 11, Seattle had him out of the game after the fifth inning. He gave up an RBI triple in the second, and a three-run fifth (with a two-run homer for Julio Rodríguez) got him yanked early.
