The Seattle Mariners starting rotation was the team's most sure thing when spring training began. The group featured three All-Stars and two more pitchers heading into their third respective seasons in the majors.

Opening Day in Seattle belongs to Logan Gilbert. The reigning All-Star and standout starter has emerged from one of the league’s premier rotations, earning his first Opening Day nod when the Mariners host the Athletics at T-Mobile Park on March 27.

Gilbert, who is entering his fifth year in the majors, put up the numbers in 2024 to lead just about any staff in baseball, throwing the most innings (208 2/3) in MLB and tying for the most starts (33) while being named to his first All-Star team and finishing sixth in the American League Cy Young Award voting.
