Mastrobuoni cleared waivers Tuesday and was outrighted to Triple-A Tacoma.
Mastrobuoni was dropped from the active and 40-man rosters Saturday to make room for Julio Rodriguez's (leg) return from the IL, but the former will officially remain in the Mariners' system after passing through waivers unclaimed. Mastrobuoni, 30, has slashed just .172/.310/.293 through 71 plate appearances at Tacoma and is likely to spend the vast majority of what's left in the season at Triple-A.

The Mariners designated Mastrobuoni for assignment Saturday.
After having his contract selected by Seattle on July 3, Mastrobuoni made only three at-bats for the big-league club before being DFA'd on Saturday. This marks the second time the 30-year-old has been designated for assignment by Seattle this campaign. With Julio Rodriguez coming back from the 7-day injured list, the Mariners needed to make room for him on the active roster.

The Mariners selected Mastrobuoni's contract from Triple-A Tacoma on Friday.
Mastrobuoni was DFA'd by the Mariners in mid-June but is back with the big club to provide depth in the outfield after Julio Rodriguez (concussion) was placed on the 7-day injured list. Mastrobuoni has spent most of the 2026 season in Triple-A, where he has a .603 OPS with five steals, one home run and three RBI over 71 plate appearances.

Mastrobuoni cleared waivers Thursday and was sent outright to Triple-A Tacoma.
Mastrobuoni was DFA'd by Seattle after going 5-for-23 with 10 strikeouts in eight games with the big club, and he'll officially remain in the organization after passing through waivers unclaimed. The 30-year-old has posted just a .649 OPS at Triple-A this season and will likely spend the vast majority of what's left of the season in the minors.

The Mariners designated Mastrobuoni for assignment Friday.
Mastrobuoni went 5-for-23 with an RBI and three runs scored during his eight-game stint with the Mariners, but he'll now lose his place on the 26-man and 40-man rosters in favor of Weston Wilson. Mastrobuoni owns just a .567 OPS across 474 plate appearances in his MLB career, but his defensive versatility could draw some attention on the waiver wire.

Mastrobuoni will start at third base and bat seventh in Sunday's game against the Nationals.
Since being reinstated from the 60-day injured list Wednesday, Mastrobuoni has gotten five straight starts (four at third base, one at second) while going 3-for-13 with a walk, a stolen base, two runs and an RBI. His run of regular playing time will likely come to an end Tuesday, however, with J.P. Crawford (hand) set to return from the 10-day IL and bump Mastrobuoni into a utility role.
