Seattle Mariners pitcher Bryce Miller has taken a positive step in his injury rehab, completing an 80% effort bullpen session without any setbacks. Miller, who was diagnosed with oblique inflammation, is expected to throw a full bullpen session later this week as the team determines the next steps in his recovery process.

Why it matters

Miller's return to the Mariners' rotation is crucial, as he was a key contributor in 2024 but was limited to just 18 starts in 2025 due to elbow injuries. If he can regain his 2024 form, it would significantly boost the Mariners' chances of contending for a World Series title.

The details

During his bullpen session, Miller reported that 'everything felt good' and he was able to throw his pitches without any issues. The team plans to have him throw a regular bullpen of 25-30 pitches at higher intensity later this week, which will help determine the next steps in his recovery process.

  • On Sunday, March 8, 2026, Miller threw a 10-minute bullpen session at 80% effort.
  • Later this week, Miller is expected to throw a full 25-30 pitch bullpen session at higher intensity.

What they’re saying

“Everything felt good. Doing all my spins, getting 15, 20 pitches on the slope and just not feeling anything was the main thing. I want to obviously throw more and like a normal bullpen and throw harder and all that, but limit the build-up, put a little governor on and make sure we do it the smart way.”
