What did Chase DeLauter do vs Mariners?

DeLauter makes a historic first impression as Guardians win

Cleveland’s season opener on March 26 came down to a standout debut from rookie Chase DeLauter, who powered the Guardians to a 6-4 victory over the Seattle Mariners.

DeLauter hit his first two career major-league home runs in the game, including a shot that arrived in the early portion of the matchup and another later on that helped keep Cleveland ahead. The offensive impact was immediate: the Guardians used those extra-base plays to create cushion while the rest of the lineup added support.

One of the key moments beyond DeLauter’s power came from Jose Ramirez, who broke a tie with a two-run double with two outs in the seventh inning. That play shifted momentum in the late innings, turning Cleveland’s lead from fragile to more manageable as the game entered its final stretch.

The Guardians’ win matters for a couple reasons.

First, it sets a clear early role for a rookie who appears ready for major-league pitching demands right away. Getting two homers in a first regular-season appearance also signals that Cleveland’s transition to new contributors is already working.

Second, it frames the Guardians’ Opening Day identity: aggressive hitting early, timely extra-base damage, and reliable late execution. Even with a close final score, the game’s decisive swing came late rather than requiring Cleveland to withstand a final-inning comeback.

Final result

• Guardians 6, Mariners 4
• DeLauter: two first-career home runs
• Ramirez: go-ahead, two-run double in the seventh

Cleveland starts the year with a statement debut, and Seattle takes a loss that underscores how quickly the Guardians can turn early offense into a close, controllable victory.
