Chase DeLauter and the Guardians beat Seattle Mariners 6-4 in the season opener at T-Mobile Park. Dominic Canzone and Luke Raley of Ohio, who combined for three home runs, scored three runs and led the team with two home runs. Despite a strong performance from Tanner Bibee, who was forced to leave the game due to shoulder inflammation, the win was marred by DeLauter's double homer and three runs. The revamped bullpen also performed well, allowing the Mariners to maintain a 3-3 lead. The win was the fifth Cleveland player to homer in his first regular season at-bat.
