The Cleveland Guardians head to Seattle to take on the Mariners in a potential playoff preview on Saturday. The Mariners are favored at home, led by ace Bryan Woo, but the Guardians are hoping rookie Chase DeLauter can keep up his hot start and help pull off the upset against the AL contenders.

Why it matters

This early-season matchup between the Guardians and Mariners could have postseason implications, as both teams are expected to be in the mix for an American League playoff spot. A road series win for the Guardians would be a statement victory, while the Mariners look to take care of business at home against a potential October foe.

The details

Seattle will send right-hander Bryan Woo to the mound, who emerged as an ace last season with a 2.94 ERA and 198 strikeouts over 186.2 innings. The Guardians will counter with lefty Joey Cantillo, who had a solid 2025 campaign with a 3.69 ERA and 10.2 K/9 rate. Cleveland's lineup lacks punch outside of Jose Ramirez, but rookie Chase DeLauter has been on a tear to start his MLB career, already hitting 3 home runs in his first two games.
