The Cleveland Guardians fell 8-0 to the Seattle Mariners in the first game of their season-opening series. Mariners pitcher Emerson Hancock threw six hitless innings, while the Guardians' offense struggled to get anything going against the dominant pitching performance.

Why it matters

The Guardians were hoping to get off to a strong start in 2026 after a disappointing 2025 season, but this lopsided loss to their division rivals is a setback. The Mariners, meanwhile, are looking to build on their success from last year and make a push for the playoffs.

The details

Hancock, the Mariners' top pitching prospect, was in complete control throughout his outing, striking out 8 Guardians batters. The Guardians' lineup, which features several young and inexperienced players, was overmatched by Hancock's stuff. On the other side, the Mariners' offense erupted for 8 runs, chasing Guardians starter Brendan McKay early.

The takeaway
