Even when the Seattle Mariners were projecting confidence in Bryce Miller's recovery from left oblique inflammation, there was still a sliver of doubt that he would be ready for Opening Day. It only grew when he tried and failed to throw a full-effort bullpen session on Wednesday.
As reported by Daniel Kramer of MLB.com, Miller was only able to get off a few warm-up pitches before pulling the plug on the session altogether. He won't be shut down from throwing altogether, and he could even throw a lower-effort bullpen session in the coming days.
