Bryce Miller will start and Luis Castillo will again be the piggyback pitcher for the Mariners on Sunday, but the team will then adopt a six-man rotation, the Seattle Times’ Adam Jude writes. Friday’s game with the Diamondbacks kicked off a stretch of 16 games in 17 days for the Mariners, so shifting back to a six-man rotation will help keep the entire pitching staff stay fresh. The rotation plan will then be re-evaluated on June 15 (Seattle’s next off-day), and sticking with the six-man format could be an option, if the M’s don’t again use two starters in a piggyback set-up.
Simply establishing a plan for the next couple of weeks is a positive step for the Mariners, as both Miller and Castillo weren’t pleased with what they felt was a lack of communication from the club. Manager Dan Wilson, pitching coach Pete Woodworth, president of baseball operations Jerry Dipoto, and GM Justin Hollander all spoke with the two right-handers this week and now everyone seems to be “on the same page,” as Miller put it. Emerson Hancock‘s breakout season has given Seattle six viable starters and a bit of awkwardness in how to best manage everyone’s workload, though in the big picture, there’s no such things as too much good pitching for a team hoping to make an even deeper playoff run.
More from around the AL West…
- Wyatt Langford is slated to start a Triple-A rehab assignment today. The Rangers outfielder hasn’t played since April 21 due to a right forearm strain, and his stay on the 10-day injured list has been longer than expected since Langford’s previous attempt at a minor league rehab stint was paused due to more forearm discomfort. Pegged by many as a candidate for a true breakout in 2026, Langford got off to a slow start before his IL placement, hitting only .238/.274/.363 in his first 84 plate appearances.
- In addition to Langford, Rangers manager Skip Schumaker also gave reporters (including the Dallas Morning News’ Shawn McFarland) updates on two other sidelined players. Corey Seager is set for a live batting practice today, a week after a previous live BP session was postponed due to more soreness in the shortstop’s ailing back. “The running has been maybe the main thing” holding Seager back, Schumaker said, through Seager has been able to play catch and take swings. Josh Smith has also rejoined the Rangers and restarted baseball activities, though as with Seager, there isn’t any timetable for when Smith might be back in the Texas lineup. A right glute strain sent Smith to the 10-day IL on May 4, but what was initially expected to be a minimal IL stint was extended due to wrist soreness, and then the more serious matter of a bout of viral meningitis that led to a hospital stay.
- Former Angels top prospect Christian Moore exclusively played second base in his first two pro seasons but he has split his time between second and third base this season at Triple-A Salt Lake. Moore is now getting a look at the entirely new position of left field, Jeff Fletcher of the Orange County Register writes. Angels assistant GM Joey Prebynski said Moore will be used at all three positions, and “for us, it’s just about continuing to get him reps out there, seeing balls off the bat in left field.” No team in baseball has gotten less from its left fielders in 2026 than the Angels, as Josh Lowe‘s struggles (and subsequent demotion to Triple-A) have been the biggest reason why the position has been a black hole for the team. With the Oswald Peraza/Adam Frazier platoon in place at second base, Moore’s next trip to the majors could very well see him get much more time away from his natural position. Moore made his MLB debut last season and hit only .198/.284/.370 over 184 PA, but he has continued to crush Triple-A pitching in his second year at the top minor league level, with a .282/.439/.481 to show for 171 PA for Salt Lake in 2026.
