Updated on July 25, 2025 at 3:15pm

The Mariners optioned Mastrobuoni to Triple-A Tacoma on Friday.

Mastrobuoni will lose his spot on the 26-man roster now that Josh Naylor (recently traded) has reported to the club. Mastrobuoni has slashed .252/.327/.293 with the Mariners and had recently been splitting time with Ben Williamson at third base.
