The Seattle Mariners promoted 20-year-old shortstop Colt Emerson from Triple-A Tacoma to the Major League roster and placed outfielder Brendan Donovan on the 10-day injured list. Emerson, the Mariners' No. 1 prospect and MLB Pipeline's No. 6 overall prospect, is set to make his big-league debut at T-Mobile Park and at 20 years and 301 days becomes the youngest Mariners debutant since Félix Hernández in 2005. The move injects a high-upside middle infielder into Seattle's roster, boosting infield depth and accelerating Emerson's development opportunity at the major league level.
