Miller (4-9) took the loss Tuesday, surrendering four runs on four hits and three walks over 3.2 innings against Texas. He struck out six.
The right-hander was scored upon in three of the four frames he pitched as he remains without a win in his past 10 outings. Miller has a 6.89 ERA, 1.65 WHIP and 39:24 K:BB across 49.2 innings during that span and has also failed to last five frames in any of his past four starts. A road matchup versus the A's at hitter-friendly Sacramento is likely on tap for his next turn through the rotation.

Mariners' Bryce Miller: Goes 4.2 innings vs. Boston
Rotowire
Miller did not factor into the decision Wednesday against the Red Sox, allowing a run on seven hits and a walk across 4.2 innings. He struck out three.
After he was demoted to the bullpen last week, the right-hander quickly rejoined the M's starting rotation after Emerson Hancock (groin) landed on the IL. Miller was limited to 65 pitches Wednesday, as he managed to work his way through traffic to hold Boston to one run. Overall, it was a step in the right direction for Miller, who struggled to a 9.00 ERA across 20 frames in his previous four starts. He'll carry a 4.01 ERA, 1.11 WHIP and 95:26 K:BB into his next outing, tentatively scheduled to come at home against the Rangers.

Mariners' Bryce Miller: Re-entering rotation
Rotowire
Miller will rejoin the Mariners rotation Wednesday in Boston after Emerson Hancock (adductor) was placed on the 15-day injured list Sunday, Daniel Kramer of MLB.com reports.
After manager Dan Wilson announced last week that the righty would be demoted to the bullpen, Miller didn't end up making any relief appearances and will now be plugged back into the five-man rotation while Hancock is out. Miller has posted a 7.18 ERA and 27:16 K:BB across 36.1 frames since the All-Star break.

Mariners' Bryce Miller: Demoted to bullpen
Rotowire
Mariners manager Dan Wilson said Friday that Miller is being moved to the bullpen, Daniel Kramer of MLB.com reports.
The club had been operating with a six-man rotation since the promotion of top prospect Kade Anderson but will revert to a typical five-man setup. Miller collected a 2.18 ERA and 65:9 K:BB over 57.2 innings in the first half, but he's cratered in the second half with a 7.18 ERA and 27:16 K:BB across 36.1 frames. In Miller's last four outings, the Mariners were outscored 62-7. Wilson noted Friday that Miller's demotion is "not a permanent thing," and that the team still views the hurler as a starter long-term.

Mariners' Bryce Miller: Struggles continue in eighth loss
Rotowire
Miller (4-8) took the loss Sunday, allowing six runs on two hits and seven walks over 4.1 innings against the Cubs. He struck out five.
Miller endured a disastrous third inning, surrendering a pair of homers as part of a five-run frame for the Cubs. His seven walks marked a career high, surpassing his previous worst of five free passes in April 2025. The right-hander has struggled mightily of late, allowing 20 earned runs across 20 innings in four August starts. With an overall 4.12 ERA, 1.09 WHIP and 92:25 K:BB in 94 innings (17 appearances), Miller will look to get back on track next time out, tentatively scheduled for Sunday against the Blue Jays.

Mariners' Bryce Miller: Tagged for six runs in rout
Rotowire
Miller (4-7) took the loss Tuesday against the Brewers, allowing six runs (five earned) on seven hits and two walks while striking out three over 4.2 innings.
Miller held Milwaukee to a single unearned run through his first four innings before everything unraveled in the fifth. He was charged with five runs in the frame, with Christian Yelich's three-run homer delivering the biggest blow, before Seattle's bullpen allowed the game to turn into a 22-0 rout. It marked Miller's first start this season in which he failed to complete five innings, while the five earned runs matched his season high. The right-hander has struggled mightily over his last seven outings, posting a 0-5 record with a 6.57 ERA. On the season, he owns a 3.71 ERA, 1.04 WHIP and 87:18 K:BB across 89.2 innings. Miller will seek to find any kind of improvement in his next start, tentatively scheduled for Sunday against the Cubs.

Mariners' Bryce Miller: Falls to Detroit
Rotowire
Miller (4-6) took the loss Thursday against the Tigers, allowing four runs on five hits and two walks across five innings. He struck out five.
Detroit got to Miller early Thursday, scoring three runs in the first inning (two coming on a Dillon Dingler homer) before giving up a fourth run in the second. Miller managed to settle in and hold the Tigers scoreless over his final three frames, but Seattle couldn't climb out of the early hole in an eventual shutout defeat. The 27-year-old Miller's been slumping of late, going 0-4 with a 5.40 ERA across 26.1 frames in his last five outings. Overall, his ERA sits at 3.08 with a 0.95 WHIP and 79:15 K:BB across 79 innings this season. Miller will look to get back on track in his next start, tentatively scheduled to come on the road next week against the Yankees.

Mariners' Bryce Miller: Acceptable outing in no-decision
Rotowire
Miller allowed two runs on three hits and two walks while striking out three over 5.1 innings in a no-decision versus the Twins on Friday.
Miller limited the damage to a two-run home run by Brooks Lee in the second inning. The Mariners' bullpen couldn't hold the lead, leaving Miller to see his winless skid reach four games, a span in which he's allowed 16 runs (13 earned) over 21.1 innings. His shaky July has taken a little shine off his overall numbers, but he still has a strong 2.80 ERA, 0.92 WHIP and 74:13 K:BB through 74 innings over 13 games (12 starts) this season. Miller is projected for a home start versus the Rays next week.

Mariners' Bryce Miller: Handed fourth loss
Rotowire
Miller (4-4) took the loss Friday versus the Giants, giving up three runs (two earned) on seven hits and one walk over 5.2 innings. He struck out six.
The right-hander kept San Francisco off the board until the fifth inning, when Bryce Eldridge launched a two-run homer to open the scoring. A hit, two errors and a hit-by-pitch resulted in an unearned run for the Giants in the sixth and prevented Miller from securing his fourth quality start of 2026. The 27-year-old has surrendered more than three runs in just one of his 11 outings this season and now has a 2.27 ERA, 0.88 WHIP and 71:10 K:BB across 65.1 innings.

Mariners' Bryce Miller: Flirts with no-no in victory
Rotowire
Miller (4-2) earned the win over the Angels on Thursday, completing seven scoreless innings during which he allowed two hits and struck out eight batters without issuing any walks.
Miller and Angels starter Walbert Urena put up matching goose eggs until Seattle broke through for a run in the sixth inning. That ended up being all the Mariners needed, as Miller combined with two relievers for a shutout. The right-hander completely dominated Los Angeles, taking a no-hitter into the seventh frame before getting tagged for a pair of singles. He tallied 15 whiffs and eight punchouts to help snap a two-game losing streak. Miller got a late start to the campaign, as an oblique strain delayed his 2026 debut until May 13. However, he's been exceptional since joining the rotation, posting a 1.71 ERA, 0.66 WHIP and 62:5 K:BB over 52.2 innings spanning nine appearances (eight starts).

Mariners' Bryce Miller: Impressive again Friday
Rotowire
Miller (3-0) picked up the win during Friday's 10-2 rout of the Nationals, allowing two runs on four hits over eight innings. He struck out seven without walking a batter.
Both runs came on solo shots by James Wood and Dylan Crews, but Miller otherwise sailed through his second straight quality start on 91 pitches (65 strikes). The 27-year-old righty hasn't given up more than two runs in any of his six outings (five starts) since making his season debut May 13, posting a 1.54 ERA, 0.71 WHIP and 36:5 K:BB through 35 innings as he puts his 2025 struggles behind him. Miller will look to stay dialed in during his next trip to the mound, which is scheduled to come at home next weekend against the Red Sox.

Mariners' Bryce Miller: Fans nine in Saturday's win
Rotowire
Miller (2-0) picked up the win Saturday, allowing one hit and two walks over six scoreless innings in a 4-0 victory over the Tigers. He struck out nine.
No longer working in tandem with Luis Castillo, Miller completed six innings for the first time in five starts since coming off the IL while setting a season high in strikeouts. The right-hander has been outstanding since making his belated 2026 debut in mid-May, posting a 1.33 ERA, 0.78 WHIP and 29:5 K:BB through 27 innings. He'll look to keep rolling in his next outing, which lines up to come on the road next week in Baltimore.

Mariners' Bryce Miller: Drawing start Saturday
Rotowire
Miller is slated to start Saturday's game against the Tigers, Adam Jude of The Seattle Times reports.
Miller and Luis Castillo worked in tandem in each of the previous three turns through the rotation, but both pitchers will receive standalone starts during the final two games of the series in Detroit. While making three starts and pitching once in relief since being reinstated from the injured list May 13, Miller has been excellent, producing a 1.71 ERA, 0.86 WHIP and 20:3 K:BB in 21 innings. He hasn't tossed more than 83 pitches or 5.2 innings in any of those outings, but Miller could have a longer leash Saturday since Castillo won't be piggybacking him.

Mariners' Bryce Miller: Records first win of season
Rotowire
Miller (1-0) earned the win over the Athletics on Monday, allowing two runs on five hits and no walks while striking out four batters over five bulk-relief innings.
Seattle went with the unorthodox pairing of Luis Castillo and Miller for Monday's contest. Castillo was excellent in tossing four scoreless innings, but Miller ended up throwing more pitches (83 to 68) and benefitted by being the pitcher of record despite entering with a hearty 7-0 lead. Miller is still somewhat working his way back after missing the early part of the season due to an oblique injury, but he's completed at least five innings and thrown at least 72 pitches in each of his three outings. It remains to be seen if the pairing of Miller and Castillo will continue moving forward, but Miller has thrived regardless of his role this season, posting a 2.25 ERA, 1.00 WHIP and 14:2 K:BB through 16 innings.

Mariners' Bryce Miller: Following Castillo on Monday
Rotowire
Mariners manager Dan Wilson said that Miller will pitch out of the bullpen behind starter Luis Castillo in Monday's game against the Athletics in Sacramento, Ryan Divish of The Seattle Times reports.
Since being activated May 13 following a season-opening stint on the injured list, Miller has looked sharp over his first two starts, covering 5.1 and 5.2 innings in those outings while posting a collective 1.64 ERA, 1.00 WHIP and 10:2 K:BB. The Mariners used Castillo for 2.1 innings out of the bullpen in Miller's latter start, and while the two will work in tandem once again Monday, the order that they pitch will be reversed. Seattle will likely let Castillo work a little bit longer in a starting role than he did as a reliever his last time out, but Miller could still end up covering the bulk of the innings, given that he's been the better performer of the two thus far. Pitching out of the bullpen may also increase Miller's odds of earning his first win of the season, after the Mariners held him to fewer than 85 pitches as a starter in both of his previous two starts.

Mariners' Bryce Miller: Dazzles in no-decision
Rotowire
Miller allowed one hit and one walk while striking out seven over 5.2 scoreless innings in a no-decision versus the White Sox on Tuesday.
Miller threw 50 of 72 pitches for strikes, a drop from the 81 pitches he threw in his season debut. Miller was in line for the win, but Luis Castillo and Andres Munoz combined to give up the one-run lead in the ninth inning. With two runs allowed on nine hits and two walks over 11 innings across two starts, Miller has looked superb since returning from an oblique strain. He's done well enough to earn another start as the Mariners continue to try to set their rotation in some way. Miller is tentatively lined up to pitch on the road against the Athletics in some capacity early next week.

Mariners' Bryce Miller: Activated for season debut
Rotowire
The Mariners reinstated Miller (oblique) from the 15-day injured list ahead of his scheduled start Wednesday in Houston.
The 27-year-old will be making his 2026 debut for the Mariners after spending the first seven weeks of the season on the shelf while recovering from a left oblique strain that he sustained early in spring training. Miller is coming off a rough 2025 campaign in which he compiled a 5.28 ERA and a middling 10.2 K-BB% over 18 starts during the regular season, though he fared better over his three playoff starts. The right-hander was generally sharp over his four-start rehab assignment (1.98 ERA, 1.17 WHIP, 14:7 K:BB in 13.2 innings), but he'll likely need to perform well upon his return from the shelf to ensure he maintains a spot in the Seattle rotation for the long haul. While Miller will receive a standalone start Wednesday, Ryan Divish of The Seattle Times relays that the Mariners plan to have him piggyback with the struggling Luis Castillo for a game during next week's series versus the White Sox. How Miller and Castillo perform in their next two appearances could determine which of the two remains in a starting role when the Mariners condense from a six-man to five-man rotation.

Mariners' Bryce Miller: Likely to return next week
Rotowire
The Mariners are leaning toward activating Miller (oblique) from the 15-day injured list next week in Houston, Adam Jude of The Seattle Times reports.
Miller threw 61 pitches over five shutout innings in his last rehab start with High-A Everett on Wednesday and declared himself "ready to go" after the outing. The Mariners haven't ruled out giving Miller one more rehab start to get further stretched out, but Jude hears it's likelier Miller's next outing is in the majors. Rejoining the rotation is just one of the scenarios the Mariners are considering for Miller, as the club is also mulling using him in the bullpen or in a piggyback role. Shifting Luis Castillo or Emerson Hancock to the bullpen is also possible, as is a six-man rotation. Seattle will make a decision on its rotation in the coming days.

Mariners' Bryce Miller: Completes second rehab start
Rotowire
Miller (oblique) struck out six and gave up one hit and one walk over three scoreless innings Friday in a rehab start with High-A Everett.
After recording just five outs on 33 pitches in his first rehab appearance with Triple-A Tacoma on April 18, Miller moved down a couple levels for his second minor-league start and delivered a much more efficient performance. During Friday's outing, he spotted 35 of his 47 pitches for strikes and induced eight swings and misses while sporting a fastball that sat between 96 and 98 miles per hour. Per MLB.com, Miller is tentatively trending toward a return from the 15-day injured list May 17, which suggests he'll need three more rehab starts prior to being activated. The right-hander has been on the shelf all season while recovering from a left oblique strain.

Mariners' Bryce Miller: Returns to mound work
Rotowire
Miller (side) threw a 25-pitch touch-and-feel bullpen session Sunday at about 80 percent intensity, Shannon Drayer of SeattleSports.com reports.
The right-hander was able to mix in all his pitches and is now scheduled for a normal 25-to-30-pitch bullpen session in a couple days. Miller was briefly shut down from throwing after receiving a platelet-rich plasma injection to treat inflammation in his left side, which has delayed his buildup during spring training. If the 27-year-old can continue to ramp up with no further issues, it's possible he can avoid a stint on the injured list to begin the season.
