Nintendo of America has expanded its long-standing partnership with the Seattle Mariners, marking a historic first with the introduction of jersey sleeve branding. The Mariners will feature Nintendo's iconic 'racetrack' logo on their home jersey sleeves and the new Nintendo Switch 2 logo on their away jerseys. This innovative approach makes the Mariners the first MLB team to don different sleeve patches for home and away games.

Additionally, Mariners All-Star centerfielder Julio Rodriguez has been named a brand ambassador for Nintendo, further solidifying the partnership. Nintendo originally acquired a stake in the Mariners in 1992, a gesture of gratitude towards Seattle for its support, although they sold most of their stake in 2016, retaining only a 10% ownership.

The Seattle Mariners made notable changes to their 40-man roster recently, resulting in several players designated for assignment. Among those affected was catcher Nick Raposo, who was sent to the Tacoma Rainiers after the team acquired utility player Miles Mastrobuoni from the Chicago Cubs. Raposo, who previously played for the St. Louis Cardinals and Toronto Blue Jays, experienced a challenging stint in Triple-A last season, hitting just .206.

With the Mariners' acquisition of Blake Hunt from the Baltimore Orioles, Raposo's potential role as an emergency catcher diminished. He will now compete with three other catchers at the Triple-A level, marking a significant shift in Seattle's depth behind the plate as they prepare for the upcoming season.

The Seattle Mariners have bolstered their infield by acquiring Miles Mastrobuoni from the Chicago Cubs in exchange for cash. Mastrobuoni, who is 29 years old, struggled last season, hitting just .194 with four RBIs over 50 games with the Cubs. His versatility allows him to cover multiple positions, including second base, third base, shortstop, and corner outfield.

This move comes as the Cubs designated Mastrobuoni for assignment to make room for newly acquired reliever Matt Festa. To accommodate Mastrobuoni on their 40-man roster, the Mariners designated catcher Nick Raposo for assignment. Raposo, 26, was previously claimed off waivers from the Toronto Blue Jays in December.

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.

The Seattle Mariners have bolstered their infield by acquiring Miles Mastrobuoni from the Chicago Cubs in exchange for cash. The 29-year-old infielder struggled last season, batting .194 with four RBIs across 50 games for the Cubs. Mastrobuoni is versatile, capable of playing second base, third base, shortstop, and corner outfield positions.

To create space for Mastrobuoni on their 40-man roster, the Mariners designated catcher Nick Raposo for assignment. Raposo, 26, was previously claimed off waivers from the Toronto Blue Jays in December. Mastrobuoni made his MLB debut with the Tampa Bay Rays in 2022, recording a career .219 batting average with one home run, nine RBIs, and 16 stolen bases in 118 games.
