Miller (3-2) took the loss Thursday against the Pirates, allowing three runs on five hits over 5.2 innings. He struck out 11.
Miller turned in another excellent outing Thursday, logging a season high 11 strikeouts. However, he'd give up three runs on a pair of homers which proved to be enough to stick Miller with the loss in an eventual 3-1 defeat. Miller now has at least seven strikeouts in each of his last four starts and he's yet to give up more than three runs in any of his first eight outings. Overall, Miller's ERA sits at a pristine 1.97 with a 0.72 WHIP and 54:5 K:BB across 45.2 innings. He's currently in line to face the Angels at home his next time out.

Mariners' Bryce Miller: Strikes out seven in loss
Rotowire
Miller (3-1) allowed one run on three hits and struck out seven without walking a batter over five innings, taking the loss Friday versus the Red Sox.
Miller was strong again, throwing 46 of 66 pitches for strikes in a planned short start with Luis Castillo working in the long-relief role. However, the Mariners got no-hit through 6.1 innings and didn't score until the ninth, leaving Miller with no run support in a hard-luck loss. The right-hander is now at a 1.58 ERA, 0.70 WHIP and 43:5 K:BB over 40 innings through seven appearances (six starts) this season. The Mariners plan to have all of their starters work in a tandem situation at least once prior to the All-Star break. With Miller getting his done now, he should see something closer to a traditional starter's workload in his next outing.

Mariners' Bryce Miller: Part of piggyback plan Friday
Rotowire
Mariners general manager Justin Hollander said Tuesday that Miller will start Friday's game against the Red Sox and will be piggybacked by Luis Castillo, Adam Jude of The Seattle Times reports.
Miller and Castillo both made standalone starts in their last two appearances as part of a six-man rotation, but the two will be deployed in tandem Friday while Seattle shifts back to a five-man setup. The Mariners previously used Miller and Castillo in a piggyback arrangement on three other occasions back in May, with Miller working between five and 5.2 innings in those contests while logging a 1.15 ERA and 0.57 WHIP. Expect Miller to handle a similar workload Friday, as Jude notes that the right-hander will be limited to around 75-to-80 pitches before turning the ball over to Castillo. Hollander relayed that all six of the team's starters will rotate through and have one piggyback outing until the All-Star break, so Miller and Castillo will likely be separated and make traditional starts when their turn in the pitching schedule comes up again next week.

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: Strong again in no-decision
Rotowire
Miller allowed a hit and a walk while striking out six over five scoreless innings in a no-decision versus the Diamondbacks on Sunday.
Miller threw 52 of 71 pitches for strikes, making this his lightest workload in four appearances (three starts) since he returned from an oblique injury. He continues to pitch well, but the Mariners are taking plenty of caution with his limited pitch counts. Miller worked in a tandem with Luis Castillo, who allowed two runs (one earned) on two hits and two walks with three strikeouts over the last five frames of the extra-inning win. Both pitchers have expressed some dislike for the tandem approach, but it's led to positive results for two consecutive turns through the rotation. Miller has an excellent 1.71 ERA, 0.86 WHIP and 20:3 K:BB over 21 innings this season. If the pitching tandem continues, Miller will get the ball at some point during next weekend's series in Detroit.

Mariners' Bryce Miller: Headed for another tandem start
Rotowire
Miller is scheduled to start Sunday's game against the Diamondbacks in Seattle and will be used in tandem with Luis Castillo, Adam Jude of The Seattle Times reports.
Though both Miller and Castillo have expressed displeasure with being deployed in a piggyback arrangement, the two pitchers will nonetheless operate in a tandem for a third consecutive turn through the rotation. The setup worked well the last time out Monday in Sacramento, with Castillo delivering four shutout frames to open the game before Miller followed with four strikeouts over five innings of two-run ball en route to picking up his first win of the season. The two will pitch in the opposite order Sunday, and while being piggybacked by Castillo will likely suppress MIller's workload, the latter should still be able to reach the five innings he would need to hit to qualify for a win in a starting role. Since being activated from the injured list May 13, Miller has covered between five and 5.2 innings and 72 and 83 pitches over his three appearances while posting a 2.55 ERA and 1.00 WHIP.
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.
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: Will be piggybacked Tuesday
Rotowire
Miller will start Tuesday's game against the White Sox and will be piggybacked by Luis Castillo out of the bullpen, Adam Jude of The Seattle Times reports.
Miller and Castillo both made their own starts last week following the former's return from the injured list, but the two will work in tandem Tuesday while the Mariners condense their rotation from six to five. Mariners manager Dan Wilson hasn't provided an indication of how the innings will break down between the two pitchers, but after covering 5.1 frames in Houston last Wednesday in his 2026 big-league debut, Miller could work deep enough into his start against Chicago to qualify for a win. The Mariners will likely see how both Miller and Castillo fare Tuesday before determining whether to keep the piggyback arrangement in place the next time the fifth spot in the rotation comes up.
