Mariners Option Struggling Rookie Colt Emerson to Triple-A

The Mariners have optioned rookie shortstop Colt Emerson to Triple-A Tacoma. Emerson, who struggled to a .190 batting average with 23 RBIs across 69 games, will head to the minors for further development. The move, confirmed Thursday, coincides with the team selecting infielder Brock Rodden to the roster. The organization looks for Emerson to refine his approach after a challenging start to his major league tenure.
