Mariners release assistant hitting coach Bobby Magallanes during spring training 2026

What happened

Adam Jude of the Seattle Times reports that the Seattle Mariners are parting ways with assistant hitting coach Bobby Magallanes during spring training. The move affects a coach who had been with the organization for one season, having joined the staff prior to 2025 alongside hitting coach Kevin Seitzer.

The timing — an off-day, spring training, before the roster has fully taken shape for the year — is the kind of quiet institutional moment that tends to arrive without fanfare and leave a trail of open questions in its wake.

Why it matters

Magallanes and Seitzer arrived in Seattle together under circumstances that were, at the time, somewhat eyebrow-raising. Both had been let go by Atlanta after the 2024 season, a decision the Braves made despite the club finishing 89-73 and qualifying for the postseason. That record ended a streak of six consecutive division titles for Atlanta. The Braves still reached the playoffs — where they were eliminated by the Padres in the Wild Card series — but the front office chose to move on from the hitting staff regardless.

Seattle picked up both coaches, a pairing that arrived with a certain narrative weight: two men dismissed despite a winning record, given a second act together in a new organization. That Magallanes is now reportedly departing after a single season — and before the 2026 campaign has even begun in earnest — adds another chapter to a story that has not been short on turns.

It is worth being precise about what the report does and does not say. Adam Jude of the Seattle Times reports the Mariners are parting ways with Magallanes. No reason has been attributed. No replacement has been named. No timetable or further personnel detail accompanies the report.

What the coaching staff picture looks like now

The departure of Magallanes reportedly leaves Kevin Seitzer, who made the same journey from Atlanta to Seattle, as the remaining half of that original pairing. Whether the Mariners intend to fill the assistant hitting coach role before the season opens, or how the remaining staff will absorb the change, is not addressed in the report.

For a club navigating a difficult stretch — more on that below — the continuity of the hitting staff is not a trivial operational question. Coaching transitions during spring training carry a different weight than midseason changes; the work of building approach, establishing relationships with hitters, and setting the philosophical tone for an offense happens in these early weeks. A vacancy at the assistant level, even one that may be filled quietly, is not nothing.

Where the club stands

A 76-86 record and elimination from both the division race and the Wild Card race is the backdrop against which this coaching change lands. The Mariners sit third in the AL West, 5 games back in the division, and rank 9th in the Wild Card standings at 8.0 games relative to the cut line. The one entry in the positive column is a current two-game winning streak — a W2 — which earns a polite nod before the broader record reasserts itself.

The Mariners are not playing for October at this point; they are playing out the schedule. And the schedule in the immediate term sends them to Globe Life Field in Texas for a three-game series against the Rangers.

On Friday, July 24, Bryce Miller is the probable starter for Seattle against MacKenzie Gore. Saturday, July 25 has Bryan Woo lined up opposite Nathan Eovaldi. The series closes Sunday, July 26 with Logan Gilbert facing Jacob deGrom — a matchup that, whatever else is happening around it, will draw eyes on its own merits.

A road series against Texas is the kind of assignment that asks questions of a club regardless of where it sits in the standings. For a team that has been eliminated and is working through a spring training coaching change simultaneously, the Rangers series arrives as a straightforward measure of how the remaining weeks of the season will be navigated.

What we don't know yet

The list of open questions here is longer than the list of established facts, which is itself short. Adam Jude of the Seattle Times establishes that the parting is happening; the report does not address why, what comes next for Magallanes, whether a replacement is being sought, or what internal evaluation of the 2025 season produced this outcome.

Kevin Seitzer's status is not addressed in the report. The broader hitting staff picture — who remains, who might be added — is similarly unaddressed. Whether this move is connected to any larger organizational review of the 2025 season is not something the available material supports characterizing.

The Mariners have not issued a public statement, per the report. This is a coaching staff transaction reported by a beat writer, not a club announcement, and the desk will treat it accordingly until the organization says otherwise.

What to watch

The most immediate question is whether Seattle moves to fill the assistant hitting coach role before the 2026 season opens in full, and who that might be. Spring training is the window in which a new coach would have the most time to establish working relationships with hitters, so the pace of any replacement process carries practical significance.

The pairing of Magallanes and Seitzer had a specific origin story — both let go by Atlanta after 2024, both landing in Seattle together. With one half of that pairing now reportedly departing, the question of how Seitzer's tenure is being evaluated, and what the organization's hitting philosophy looks like heading into 2026, becomes a thread worth following as spring training continues.

The Rangers series beginning Friday offers the most immediate baseball to watch, with Miller, Woo, and Gilbert lined up in succession. The front-office and coaching staff questions this report opens will take longer than a weekend series to resolve.
