Mariners Trade: Mariners sign another Red Sox blockbuster key man

With the July 31 trade deadline fast approaching, the Seattle Mariners appear to be finding their rhythm at just the right moment. While overtaking the Houston Astros—who hold a 6.5-game lead in the AL West—might be unrealistic, the Mariners remain firmly in the hunt for a Wild Card spot.

The series against the New York Yankees hasn’t started ideally, but Seattle’s postseason hopes are still alive, with FanGraphs projecting a 61.6% chance of making the playoffs. As a result, the Mariners are positioning themselves as active buyers. If they go all-in as reports suggest, their headline move might involve a surprising name.

According to Jim Bowden of The Athletic, the Mariners’ top trade target could be Boston Red Sox third baseman Alex Bregman—a longtime rival who’s been having a standout season. While the Red Sox are reportedly trying to extend Bregman, his strong performance this year makes it likely he’ll opt out of his current deal in search of a bigger payday. If contract talks fall through, Boston may explore trade options, with Seattle seen as a top contender.

Thanks to their deep farm system, the Mariners are well-equipped to meet Boston’s needs. With top prospects like Kristian Campbell, Marcelo Mayer, and Roman Anthony now promoted to the majors, the Red Sox may look to restock their pipeline.

The Mariners, meanwhile, have an urgent need at third base. Their current production at the position ranks 16th in MLB with a .675 OPS, while Bregman is posting a .938 OPS over 226 plate appearances—his best offensive output since 2019. Although he’s been sidelined since May 23 due to a quad injury, he’s expected to return soon, possibly even before the All-Star break.

Trade rumors linking Bregman to Seattle have been circulating for weeks, but whether they materialize remains to be seen. Mariners fans have learned to treat speculation with caution, but the stakes this year are high. This deadline could be pivotal—will Seattle make the bold move to push for a deep playoff run, or will they come up short once again?
