DeLauter became the third player in major league history to hit a home run in each of his first three games. He launched a two-run shot off closer Andrés Muñoz to give Cleveland the lead for good.
The Mariners tied the game in the ninth on Julio Rodríguez’s RBI single, but Cleveland held on for the win. José Ramírez recorded his 400th career double, while Connor Brogdon earned the save.
