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.

After weeks of debate, intrigue and what Dan Wilson called “a very tough decision,” the Mariners manager and Seattle’s front office were finally ready to reveal their Opening Day starter on Saturday morning.

After the Mariners announced Logan Gilbert as the opening day starter, Luis Castillo was super happy for his teammate.
