The Chicago Cubs have traded Miles Mastrobuoni to the Seattle Mariners for cash considerations after designating him for assignment last week. Mastrobuoni, who predominantly played as an infielder, occasionally stepped into outfield roles during his time in Chicago. The 29-year-old made his MLB debut in 2022 and had a two-year stint with the Cubs, participating in 110 games.

In 2023, he recorded a 0.5 WAR over 60 games, providing serviceable defensive versatility. However, his offensive performance was lackluster, with a batting line of .241/.308/.301, one home run, and a 70 OPS+. His role diminished in 2024, playing in 50 games and slashing .194/.245/.224. The Cubs are looking to make additional roster adjustments as they prepare for the future.
