Feels ready to return
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.
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.

Covers 64 pitches in rehab start
Kirby (shoulder) allowed four earned runs on 10 hits and no walks while striking out four over four innings in his rehab start for Triple-A Tacoma on Friday.
Analysis
Kirby made his third start for Tacoma while he continues to get stretched back out after having spent all season on the injured list due to right shoulder inflammation. Though he got knocked around a bit Friday, Kirby was able to push his pitch count up to 64 and reached 97.5 miles per hour with his fastball. The Mariners haven't officially commented on Kirby's next steps, but Adam Jude of The Seattle Times notes that the right-hander could return from the IL to make his season debut with Seattle in his next outing. The 27-year-old has been sticking to a five-day rest schedule during his rehab assignment, so if he's activated during the upcoming week, he would likely line up to take the hill Thursday in Houston.

Set for another rehab start
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.
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 in the middle of next week.
