July 5: Bryan Woo (right hamstring strain) to begin Minor League rehab assignment
The electric righty will pitch at High-A Everett on Saturday, with the target of 45-50 pitches. The Mariners also aren't ruling out a possible return for Woo before the All-Star break. He's eligible to be activated from the 15-day IL next Wednesday.

"I would love to have him back as soon as possible, but everything is dependent on how he comes out of the rehab outing," Mariners manager Scott Servais said. "I hope so. Also, we're not going to activate him and put them in a big league game if he can only go out and throw two innings. That doesn't help us. He really needs to go out and be able to compete and carry that workload of four or five innings."

July 5: RHP Gregory Santos (right lat strain) to continue rehab at High-A Everett
The flamethrower will transition his rehab to High-A Everett on Saturday, roughly 35 miles north of T-Mobile Park, after Triple-A Tacoma hit the road to Salt Lake.

In his rehab outing on Tuesday, Santos was hitting 97-99 mph on his fastball with his slider in the 87-90 mph range, according to Triple-A Tacoma radio broadcaster Mike Curto. Santos had one strikeout and surrendered one hit. The plan is for him to make at least one or two more rehab appearances, after which he could be activated.

Santos isn't expected to go back-to-back days during his rehab, which could be a sign of how the Mariners intend to deploy him once he returns.

"We're going to have to be very guarded on how we use him and kind of build him up," manager Scott Servais said. "It'll be an inning at a time here or there. There will be some days off in between. So again, just trust the player, listen to the player."

July 2: RHP Chris Devenski signed to Major League contract
Long admired by Mariners president of baseball operations Jerry Dipoto, Devenski joined the club two days after being released by the Rays and one week after he was designated for assignment. He will report to Triple-A Tacoma, and his addition brought Seattle's 40-man roster to 39.

Devenski, 33, made 19 appearances for Tampa Bay, pitching at least two innings nine times. As constructed, the Mariners don't have a reliever who can consistently pitch that length.

"You can't have enough quality guys or arms to help you out," Mariners manager Scott Servais said. "Things happen sort of throughout the course of the season and as you get into the second half, so we'll just have to wait and see how that plays out."

For the season, Devenski -- a nine-year veteran who spent his most prominent days with the Astros -- had a 6.75 ERA with a 1.58 WHIP, 24 strikeouts, 14 walks and nine homers surrendered in 26 2/3 innings. He could also be an option against lefties, with a career .653 OPS and .212 batting average against in those matchups.

10-DAY/15-DAY INJURED LIST

LHP Gabe Speier (left rotator cuff strain)
Expected return: After the All-Star break
Speier is progressing toward throwing a live batting practice during the Mariners' upcoming road series in San Diego, which begins on July 9. The Mariners haven't put an exact timetable on his return, but he's long indicated that it would be some time after the All-Star break. Once he clears his next step, Speier will need a Minor League rehab assignment to ramp up, given how long he's been sidelined. His injury crept up after his most recent outing on May 29 against Houston, but he said there was no specific moment. An MRI revealed the issue. This is the first time he's been on the injured list for an arm-related issue since breaking into the Majors in 2019. (Last updated: July 4)

RHP Bryan Woo (right hamstring strain)
Expected return: Possibly before All-Star break
Woo was slated to begin a Minor League rehab assignment with High-A Everett during the weekend of July 5-7, after throwing two bullpen sessions at T-Mobile Park during Seattle's most recent series against the Orioles. The Mariners aren't ruling out a return when he's eligible to be activated on July 10, but Woo will also need to be able to clear at least 4-5 innings in a big league game to do so. Woo suffered a "low-level" strain during a June 24 start against the Rays, which forced him to exit early. Woo, who missed the season's first six weeks with right medial elbow inflammation and has seen his workload rigorously monitored since returning, said that he's never dealt with a lower body injury before.

60-DAY INJURED LIST

RHP Gregory Santos (right lat strain)
Expected return: July
Santos looked sharp to begin his Minor League rehab assignment with Triple-A Tacoma on July 2, firing his fastball up to 99 mph while mixing in a few sliders. The plan is for him to make at least one more appearance, if not more, with High-A Everett. And Mariners manager Scott Servais indicated that even after Santos is activated, the club will still diligently monitor his workload, and he won't go back-to-back days right away. The hard-throwing righty has been battling a strained latissimus dorsi all season, which has postponed the debut of the Mariners’ offseason acquisition. (Last updated: July 4)

RHP Matt Brash (right elbow inflammation)
Expected return: June 2025
Brash is out of the protective brace that he'd been wearing since undergoing Tommy John surgery on May 8 and remains in Arizona recovering. He may join the Mariners in and out in Seattle throughout the remainder of the season. Brash's surgery ended his 2024 season, three months after initially experiencing soreness during his second bullpen session in Spring Training. Brash had the ulnar collateral ligament in his pitching elbow repaired and a brace installed, which has typically allowed patients to begin physical therapy sooner. That's why the Mariners are hopeful Brash can return in 12 months, potentially as soon as June 2025. (Last updated: June 12)

OF/UTL Sam Haggerty (torn right Achilles)
Expected return: May 2025
Haggerty tore his right Achilles on May 18, in his second game after getting optioned back to Triple-A Tacoma, and he underwent surgery with Dr. Albert O. Gee at the University of Washington the following week. He then departed for Arizona shortly after to transition his recovery there. Before leaving Seattle, Haggerty mentioned in passing that his timeline would be around 12 months if all goes well with his subsequent rehab. (Last updated: June 12)

RHP Jackson Kowar (right UCL surgery)
Expected return: 2025
Kowar was transferred to the 60-day IL shortly after receiving word that he would need to undergo Tommy John surgery, which ended his season before it even began. The former first-round Draft pick was among the leading candidates to win a bullpen spot before suffering the injury in his second Cactus League outing. (Last updated: March 10)
