Vargas has been on the shelf all season while recovering from a right lat strain, which he sustained in spring training. Even though Vargas projects to serve as a middle reliever and won't need to get stretched out for more than an inning or two, the Mariners are content to have him move through his throwing program slowly. A more definitive target date for his return should become available once he's ready to head out on a rehab assignment.

Wilson began his rehab assignment with Everett last Friday and moved up to Tacoma on Tuesday. He's been shelved since early May with a fractured left thumb and could need a few more rehab games before the Mariners consider returning him to their active roster.

Criswell initially landed on the injured list last Tuesday with a shoulder strain, but further testing determined the issue to be in his pec. He's scheduled to undergo another MRI in 3-to-4 weeks, at which point he may be cleared to begin a throwing program. If all goes according to plan, the Mariners expect to activate the 29-year-old reliever sometime around the Aug. 3 trade deadline.

Donovan has been sidelined since suffering a left groin strain in mid-May, and he's now set to start running again. Based on the injury, the running program is the largest hurdle for the 29-year-old, and it's expected to last between 10 days and two weeks. If all goes well, Donovan would then be in a position to begin a minor-league rehab assignment.

Brash has suffered multiple right lat strains this season, though Hollander noted that his latest injury is in a different spot than the one that kept him out for three weeks in May. He also said that the 28-year-old righty is facing a longer stint on the IL this time around and is likely to return sometime around late July or early August. Until then, Jose Ferrer, Gabe Speier and Eduard Bazardo figure to work more often in high-leverage situations.

Dunning had to settle for a minor-league deal after posting a 6.97 ERA and 21:7 K:BB over 20.2 innings between Texas and Atlanta in 2025. The 31-year-old could be useful swingman depth for Seattle at Triple-A Tacoma.

The transaction clears a spot on the 40-man roster for the arrival of Josh Simpson, who was acquired via trade with the Marlins on Monday. Evans will miss the entire 2026 season after undergoing UCL reconstruction surgery with an internal brace in January.
