SEATTLE – Seattle Mariners Executive Vice President & General Manager of Baseball Operations Justin Hollander announced today the following roster moves:
- Will Wilson (#7), INF, selected from Triple-A Tacoma.
- Brendan Donovan, INF/OF, placed on 10-day Injured List (left groin muscle strain, retroactive to April 18).
- Miles Mastrobuoni, INF/OF, transferred to 60-day Injured List.
The Mariners 40-man roster remains full at 40 players.
Wilson, 27, will make his Mariners debut when he first appears in a game. The right-handed hitting infielder appeared in 34 games with Cleveland in 2025, batting .192 (15x78) and played second base and third base.
Wilson was signed by Seattle to a minor league contract with an invitation to Major League Spring Training on Jan. 26, 2026. In 14 games with Triple-A Tacoma this year, Wilson is batting .275 (11x40) with 4 runs, 2 doubles, 1 homer, 4 RBI and 7 walks with a .783 OPS.
The North Carolina native was originally selected by the Los Angeles Angels in the 1st round (15th overall) of the 2019 MLB First-Year Player Draft out of North Carolina State University in Raleigh. He was traded by the Angels to the Giants on Dec. 10, 2019 in a deal that involved infielder Zack Cozart, and selected by Cleveland in the 2024 Rule 5 Draft from San Francisco.
Donovan, 29, is batting .304 (17x56) with 7 runs scored, 3 doubles, 3 home runs, 8 RBI and 9 walks in 18 games to begin his Mariners career, getting on base at a .437 clip, slugging .518 with a .954 OPS and 180 OPS+.
The left-handed hitting infielder/outfielder is tied for the Major League lead with 2 leadoff home runs this year, which included becoming the first player in Mariners history to hit a leadoff home run on Opening Day (March 26 vs. Cleveland).
Donovan spent his first 4 seasons (2022-25) with the St. Louis Cardinals and was acquired by Seattle on Feb. 2, 2026 as part of a three-team trade with the Tampa Bay Rays. Defensively, he has appeared exclusively at third base for the Mariners but has also played second base, left field, right field, first base, and shortstop throughout his career. Donovan won a Gold Glove Award in 2022 and made the NL All-Star team in 2025.
Mastrobuoni (mass-troh-BO-nee), 30, has been on the 10-day Injured List this season with a right calf strain. The left-handed hitting infielder/outfielder appeared in 76 games with the Mariners last season.
