The Chicago Cubs have officially traded infielder/outfielder Miles Mastrobuoni to the Seattle Mariners following a designation for assignment. The 29-year-old player, who debuted with the Tampa Bay Rays in 2022, has struggled offensively with a lifetime batting average of .219 and a dismal .194 in the previous season with the Cubs.

In Seattle, Mastrobuoni is expected to compete for a spot as the Mariners are looking to strengthen their infield. The team has only made one significant move in free agency by signing Donovan Solano, who will likely share duties at first base and potentially second and third base. Mastrobuoni's left-handed batter profile may complement manager Dan Wilson's strategies.
