During 2025 Spring Training, Seattle Mariners utility man Miles Mastrobuoni displayed versatility on the field playing multiple positions (3B, 2B, CF, and LF) and demonstrated his prowess at the plate (.429 batting average with three doubles, one triple, five walks, seven RBI, seven runs scored and one stolen base). M’s manager Dan Wilson said, “There’s been a lot of guys that have had good springs. Mastrobuoni has been one of those guys that has put up some good at-bats and had some key RBIs for us late in games.” As a result, Miles was selected as one of 26 players on the 2025 Seattle Mariners Opening Day roster.

Selected in the 14^th round of the 2016 draft by the Tampa Bay Rays out of the University of Nevada, Reno. Northern California native Miles Mastrobuoni made his MLB debut on September 22, 2022 after spending seven seasons in the minor leagues. In 2022, he appeared in 129 Triple-A games and put together a .300 batting average with 16 home runs, 32 doubles, three triples and 16 home runs. The speedster was also successful in 23 of 26 stolen base attempts.

Mastrobuoni was traded by the Tampa Bay Rays to the Chicago Cubs in exchange for RHP Alfredo Zarraga on November 15, 2022.  He has played at every infield position but first base and the corner-outfield positions over the course of his three-year MLB career. The Seattle Mariners acquired the proud Italian American on January 14, 2025 from the Chicago Cubs for his defensive versatility and speed (16 of 17 in MLB stolen base attempts).

Under the guidance of National Baseball Hall of Famer and Team Italy manager Mike Piazza during the 2023 World Baseball Classic, Azzurri second baseman Miles Mastrobuoni went 5-for-18 with two doubles, one walk, two RBI, one run scored and one stolen base to lead the Italians to the their best-ever WBC finish in the Tokyo quarterfinals. He is one of the most underrated players in MLB. The soon-to-be Mariners fan favorites rises to the occasion when asked to perform at a high level and delivers when needed most. Forza #Italia!
