Throughout the course of a minor-league season, players will shuttle back and forth between affiliates almost daily due to injuries and roster attrition.
But the top prospects usually remain in place at one affiliate until their performance dictates a change is necessary, hopefully for the better.
On Monday, two of the Mariners’ top-performing prospects earned significant promotions to the next step of the minor-league ladder, moving them achingly close to the big leagues.
Right-hander pitcher Logan Gilbert and switch-hitting catcher Cal Raleigh were both promoted to Class AA Arkansas from High A Modesto on Monday. They’ll join a loaded Travelers team that features several of the top prospects in the Mariners retooled farm system.
