Mariners manager Dan Wilson said Wednesday that Kirby (shoulder) will be activated from the 15-day injured list to start Thursday's game in Houston, Bob Condotta of The Seattle Times reports.
EDGE Analysis
Kirby's third and final rehab start wasn't great from a results perspective, as he allowed four runs on 10 hits over four innings of work at Triple-A Tacoma last Friday. However, he got his fastball velocity up to 97.5 miles per hour in the outing, and the Mariners are convinced the right-hander is ready to face big-league hitters. Kirby threw 64 pitches in his final rehab outing, so he will be working with a relatively limited workload Thursday. He's been out all season while recovering from right shoulder inflammation.

Kirby (shoulder) said Sunday that he's ready to rejoin the Mariners after making his third rehab start Friday, though a decision has yet to be made on whether he'll require another outing in the minors before being activated from the injured list, Adam Jude of The Seattle Times reports.
EDGE Analysis
The right-hander's personal attitude is encouraging, but Seattle could still elect to send him for another rehab start after he threw 64 pitches and allowed four runs on 10 hits across four innings Friday. Kirby has been on the shelf all season due to shoulder inflammation, but he appears to be on the cusp of his 2025 MLB debut, even if he does end up making one more appearance in the minors.

Kirby (shoulder) allowed four runs on 10 hits and no walks while striking out four over four innings in his minor-league rehab start for Triple-A Tacoma on Friday, Adam Jude of The Seattle Times reports.
EDGE Analysis
Friday marked Kirby's third outing in the minors amid his recovery from right shoulder inflammation, with Jude noting the hurler's next start could come with the Mariners. Kirby got his fastball velocity up to 97.5 mph, per Daniel Kramer of MLB.com, and he was able to throw 64 pitches. The 27-year-old right-hander will be aiming to build up his pitch count even further in his next outing, which should come either in the minors once more or perhaps in Thursday's series opener against the Astros to aid Seattle's injury-ravaged rotation.

Kirby (shoulder) is expected to make another minor-league rehab start with Triple-A Tacoma on Friday in Albuquerque, Daniel Kramer of MLB.com reports.
EDGE Analysis
Kirby completed his second rehab start with Tacoma on Saturday, surrendering three runs on four hits and two walks while striking out five batters over three innings. The right-hander has missed the entirety of the 2025 campaign so far while recovering from right shoulder inflammation and if all goes well Friday, he'd be on track to return to the major-league roster late next week.

Kirby (shoulder) completed his second minor-league rehab start with Triple-A Tacoma on Saturday, allowing three runs on four hits and two walks with five strikeouts in three innings, Daniel Kramer of MLB.com reports.
EDGE Analysis
Kirby threw 54 pitches (36 strikes) Saturday, and his fastball touched 97 mph. The hard-throwing right-hander is next expected to make a third rehab appearance while he enters the final stages of his recovery from right shoulder inflammation. If all continues to go well, Kirby should be able to make his season debut for the Mariners at some point before the end of May.

Kirby (shoulder) is scheduled to make another minor-league rehab start for Triple-A Tacoma on Saturday, Daniel Kramer of MLB.com reports.
EDGE Analysis
Kirby threw 42 pitches in his first rehab outing last Sunday, and he's in line to build up to around 60 pitches in his second appearance Saturday. The right-hander is working his way back from right shoulder inflammation, and Kirby is also expected to make a third start before rejoining Seattle's rotation. That gives him a chance to make his season debut before the end of May, barring any setbacks along the way.

Kirby (shoulder) struck out four and allowed one earned run on one hit and no walks over three innings in his first rehab start for Triple-A Tacoma on Sunday.
EDGE Analysis
Pitching in a game setting for the first time since Feb. 26, Kirby performed about as well as the Mariners could have hoped, with a one-out solo home run in the third inning representing the only damage on his line. He otherwise avoided mistakes while spotting 33 of his 42 pitches for strikes and topping out at 97.8 miles per hour with his sinker. Mariners president of baseball operations Jerry Dipoto told MLB Network on Friday that he expects Kirby to require just 2-to-3 rehab starts prior to returning from the 15-day injured list, so the right-hander will be in line for another appearance in the minors next weekend before the organization determines his next step.

Kirby (shoulder) will begin his rehab assignment with Triple-A Tacoma on Sunday, Adam Jude of The Seattle Times reports.
EDGE Analysis
Kirby is in the final stages of his recovery from right shoulder inflammation that caused him to be placed on the 15-day injured list at the beginning of the season. He's slated to make his first rehab outing Sunday, and he'll need at least two or three starts in Triple-A before making his way back to the majors.

Mariners president of baseball operations Jerry Dipoto said Friday on MLB Network that he's "hopeful" Kirby (shoulder) will rejoin the rotation before the end of May, Shannon Drayer of SeattleSports.com reports.
EDGE Analysis
Kirby has been ramping up his throwing without issue and could begin a rehab assignment as soon as this weekend. The right-hander will make "at least two, maybe three" rehab starts, per Dipoto. Kirby has been working his way back from right shoulder inflammation, an injury that first cropped up in early March.

Kirby (shoulder) could begin a rehab assignment as soon as Sunday, Daniel Kramer of MLB.com reports.
EDGE Analysis
Kirby threw a live batting practice session Monday and described it as "nasty," adding that he "felt great." He will throw again Sunday, and it will be determined soon whether that will be in an official game setting. Kirby has been slow-played as he works his way back from right shoulder inflammation but has been checking every box along the way.
