Guardians shut out Mariners in season opener.
The Seattle Mariners will face off against the Cleveland Guardians in Game 4 of the MLB season, with Marco Gonzales making his first start of the season. It's also Kids Opening Day, where children 14 and under will receive a Luis Castillo t-shirt. The Guardians will have José Ramírez as DH, while the Mariners will have AJ Pollock making his debut. In Mariners history, Ichiro made his MLB debut 20 years ago, while the Mariners won their 2021 season opener with a walk-off walk.
