This would be the first major tournament call for Mastrobuoni, who was picked by Rays with his Round 14 selection back in 2016. The 26-year-old Mastrobuoni has never had much fanfare potential despite consistently producing at above-mid-level in the palace. Baseball America ranked him 20th among Tampa Bay growers in the Rays’ mid-season update—the first time he’s appeared among the top 30 teams there. FanGraphs listed it at number 37 among Rays’ prospects back in March.
The increased interest in the left-handed utility man is understandable, given his production in recent seasons. Mastrobuoni split the 2021 season between Double-A and Triple-A, reaching a total of 298/.376/.424 clips in 434 board appearances. This year in Triple-A, he’s kept hitting average and drawing a high clip gait, but he’s also lowered his hit rate and shown strength unseen before. In 573 board appearances, Mastrobuoni lowered 0.300/.377/.469 with the most goals he scored in his career prior to the 2022 season (13). He’s also turned 32 doubles in his career and blasted his 23 best stolen bases (in 26 attempts).
As with many players who come through the Rays system, Mastrobuoni is used to playing multiple positions. He’s scored 463 runs in second base this season, but has also seen action in right field (201 innings), left field (147 in), middle field (123 in), short (96 in) and in third base (17 rounds) . This defensive diversity isn’t a new trait either; Mastrobuoni has had at least 42 career games in all six of these positions, although second base was his most on diamond.
Now that he’s on the 40-man roster, the Mastrobuoni could serve as a resilient depth slasher in Tampa Bay for the foreseeable future. He will be under club control for at least the 2028 season and will be available for the next three years.
