Three Players the Seattle Mariners Could Trade Off Major League Roster at Deadline

With one week until the Major League Baseball trade deadline, the Seattle Mariners are reportedly going to be aggressive in looking for organizational improvements. The team could stand to get help at third base, first base and in the bullpen.

And while much of the attention is on the M's ability to deal from a top-flight farm system, they also have current big leaguers that could be dealt to help facilitate action. We take a look at the three most likely big leaguers to be moved below:

Dominic Canzone, OF

Originally acquired by the Mariners in 2023 from the Arizona Diamondbacks, struggled to find his footing with the M's early on. He hit just .215 post-traded in 2023 and then hit .196 in 2024, only getting 67 games of big-league action.

The power is real, and he's had a considerably better approach since coming back to the big-league roster in June. He's hitting .303 in 35 games with six home runs and 13 RBIs. He's also under team control through 2029, so a team would have several years to benefit from these possible improvements.

And while the Mariners can't necessarily bank on it, they do have Victor Robles scheduled to come back in September, meaning the outfield could get full quickly.
