Spring training is supposed to be the season of optimism, the quiet stretch where teams fine-tune rosters and players build momentum toward Opening Day. But inside the camp of the Seattle Mariners, the early weeks of preparation have also delivered a trio of injury storylines that fans are watching closely. Two familiar names are moving cautiously toward full strength, while a new entry has suddenly appeared on the team’s injury report, creating a mixture of relief, concern and cautious optimism across the organization.
The most encouraging update comes from the Mariners’ bullpen, where electric reliever Matt Brash appears to be steadily working his way back into game readiness. Brash’s spring routine was briefly interrupted earlier in camp due to dental surgery, a surprisingly disruptive issue for a pitcher whose preparation typically follows a strict rhythm. The procedure forced the right-hander to adjust his schedule, delaying his progression toward live competition.
Now, however, the momentum appears to be returning. Brash recently threw his second live batting practice session of the spring, and for the first time hitters were cleared to swing. That detail may sound minor, but it marks an important step in any pitcher’s return to competitive form. Two Mariners hitters—Brendan Donovan and Ryan Bliss—each stepped in for multiple looks against the hard-throwing reliever, giving the coaching staff a clearer picture of where Brash stands physically.
The early signs were promising. Brash’s fastball was reportedly sitting around 96 miles per hour, and his devastating sweeper—a pitch that has become one of the most difficult breaking balls for hitters to track—looked sharp. More importantly, the session unfolded without any setbacks, reinforcing the belief that Brash is closing in on a return to full competition.
If the current timeline holds, the Mariners hope Brash can still appear in five or six Cactus League games before the regular season begins. That would provide just enough game exposure for the bullpen weapon to regain his rhythm and enter the year fully prepared to handle high-leverage innings. For a team that relies heavily on bullpen depth, getting Brash back on schedule could prove critical.
While the bullpen delivered encouraging news, the situation surrounding starting pitcher Bryce Miller remains a careful work in progress. Miller has been recovering from inflammation in his oblique, an injury that can be particularly troublesome for pitchers because it affects the rotational power required in every throw.
This week, however, Miller reached a notable milestone in his recovery. The young right-hander was seen throwing from 120 feet during a structured session, working under the watchful eyes of both a coach and a trainer. After stretching out his arm, he began gradually shortening the distance while mixing in a series of throws from flat ground.
The session did not end there. Miller also progressed to a plyo mound, where he performed several dry throwing motions without a baseball before transitioning into mid-effort throws using plyo balls against a wall. It may sound like a technical routine reserved for pitching laboratories, but these incremental steps represent the careful rebuilding process designed to ensure Miller’s core muscles are fully stable before he returns to game action.
Perhaps the most significant detail of the day was that this marked the first time Miller had thrown from any mound surface since the oblique issue surfaced earlier in camp. According to the pitcher himself, the session went smoothly without discomfort. While the Mariners have not announced a specific return date for him to appear in spring games, the trajectory appears encouraging. For now, the organization seems content to allow Miller’s progress to unfold step by step rather than rushing him into a timeline that could risk reinjury.
Just as the Mariners were beginning to feel positive about those two recoveries, however, a new name surfaced on the injury report.
Right fielder Victor Robles has been absent from game action this week, prompting immediate curiosity among fans who had grown used to seeing his speed and defensive range in the outfield. The reason quickly emerged: Robles had been dealing with shoulder soreness after making a diving attempt for a ball during a game late last week.
For any outfielder, particularly one known for aggressive defensive plays, shoulder discomfort can be a worrying development. Fortunately for Seattle, the initial medical results delivered a wave of relief. The Mariners sent Robles for an MRI, and the scan returned clean, showing no structural damage.

That clean bill of health means Robles’ absence is likely precautionary rather than long-term. In fact, the Mariners are already planning for his return to the lineup. The expectation is that he will rejoin the team as the designated hitter during Sunday’s game against the Milwaukee Brewers, a move designed to ease him back into action without immediately placing stress on his throwing shoulder.
Taken together, the three updates paint a picture that is far more reassuring than alarming. Brash appears nearly ready to return to game action, Miller is advancing carefully through the final stages of his recovery program, and Robles’ injury scare seems to have been avoided altogether.
Still, spring training has a way of reminding teams how fragile a roster can be. Every pitch, every swing and every diving catch carries risk. For the Mariners, the challenge now is to navigate the final weeks of camp without further setbacks.
Because if these players return to full strength, Seattle may enter the season with something every contender desperately needs: momentum—and a roster that survived spring training stronger than expected. ⚾🔥
