The Seattle Mariners have trimmed their spring training roster to 48 players, a move that included sending top pitching prospect Kade Anderson to the minors. Anderson, the No. 3 pick in the 2025 MLB Draft, is a key part of the Mariners' future, but for now, he'll continue to hone his skills in the minor league camp.
Alongside Anderson, the Mariners made several other roster adjustments. Left-handed reliever Robinson Ortiz is heading to Triple-A Tacoma, while right-handers Randy Dobnak and Guillo Zuñigo, catcher Brian O’Keefe, and infielders Will Wilson and Patrick Wisdom have been reassigned to minor league camp.
Currently, the Mariners' spring roster consists of 48 players, featuring 34 from the 40-man roster, 13 non-roster invitees, and one player on the 60-day injured list.
Anderson, at just 21 years old, showcased his potential during his final big league camp start against the Dodgers. He gave up three runs on three hits, walked two, and struck out four over three innings.
Over the course of three spring outings, Anderson recorded a 6.43 ERA, allowing five runs on seven hits and three walks, while striking out nine in seven innings. Ranked as the No. 2 prospect in the Mariners' organization and 21st overall by MLB Pipeline, Anderson is certainly one to watch.
Ortiz, acquired in a trade with the Dodgers last November, is another intriguing arm. The 26-year-old reliever allowed five runs on six hits and two walks, with five strikeouts over 4 2/3 innings in six spring appearances.
Dobnak, a seasoned 31-year-old, joined the Mariners on a minor league deal in November. His spring performance saw him give up 11 runs (10 earned) on 15 hits, striking out six over 6 2/3 innings in four games.
Zuñigo, fresh off pitching for Colombia in the World Baseball Classic, made three appearances in camp. The 27-year-old right-hander allowed five runs on six hits and three walks, striking out four over 2 1/3 innings.
O’Keefe, a 32-year-old catcher, returned to the Mariners on a minor league contract in January. In seven spring games, he went 1 for 6, drawing five walks and striking out twice.
Wilson, a former first-round pick, joined Seattle in January. The 27-year-old infielder posted a .273 average (6 for 22) with two doubles, an RBI, five walks, and five strikeouts in 17 spring games.
Wisdom, known for his power-hitting with the Cubs, signed with the Mariners in January. The 34-year-old hit .242 (8 for 33) with two homers, a double, seven RBIs, a walk, and 17 strikeouts in 11 spring games. His ability to go deep could be a valuable asset as the season progresses.
The Mariners are clearly focused on shaping a competitive roster, and these moves reflect their commitment to developing talent while maintaining depth across the board.
