The Mariners reassigned Castillo to minor-league camp Monday.

After spending the past two seasons in Japan's Nippon Professional Baseball, Castillo returned stateside over the winter, joining the Mariners on a minor-league deal that included an invitation to spring training. The 30-year-old didn't mount much of a case for a spot in Seattle's Opening Day bullpen, giving up three earned runs on nine hits and two walks while striking out five over five innings across his three Cactus League appearances. Castillo is expected to report to Triple-A Tacoma to begin the 2025 season.

The Mariners reassigned Diaz to minor-league camp Monday.

Diaz has been getting stretched out as a starter during spring training, but he wasn't in contention for a spot in Seattle's Opening Day rotation, even with the Mariners set to begin the campaign without George Kirby (shoulder). Emerson Hancock is expected to get the first crack at replacing Kirby, but Diaz could be among the next pitchers in line to make spot starts if the Mariners lose another rotation member to an injury. Diaz will continue to make regular turns through the rotation at Triple-A Tacoma until he might be needed by the big club.

The Mariners reassigned Medina to minor-league camp Monday.

Medina will likely open the 2025 season as a reliever at Triple-A Tacoma. The 28-year-old righty hasn't appeared in the big leagues since the 2022 season, when he made 14 relief appearances for the Mets.

The Mariners optioned Bolton to Triple-A Tacoma on Monday.

Bolton has allowed just one unearned run over 3.2 Cactus League innings but also has a 2:3 K:BB over that stretch. He'll start the season at Tacoma as relief depth.

Law has made it his goal to break the Nationals' franchise record for innings pitched in a season by a reliever, Mark Zuckerman of MASN Sports reports.

The 34-year-old right-hander handled 90 innings last season, the most by a Washington reliever in the regular season since Tyler Clippard in 2010 and just three frames shy of Saul Rivera's record, set in 2007. As a result of that elevated workload, Law has been brought along slowly in camp and pitched to batters for the first time Monday on a back field, tossing 30 pitches. There's still time for him to get in Grapefruit League action before Opening Day as he prepares for work as a setup man ahead of closer Kyle Finnegan -- in addition to his 90 innings in 2024 being a career high, Law's 17 holds were also a personal best.

The Royals reassigned Fernandez to minor-league camp Monday.

Fernandez was among the six Royals who were sent to minor-league camp Monday in the latest round of roster cuts. The 28-year-old reliever made 50 appearances at the big-league level between stops with the Cardinals and Pirates from 2019 through 2022, but he spent the entire 2023 season in the minors before linking up with the Chiba Lotte Marines of Japan's Nippon Professional Baseball in 2024. Now back stateside with the Royals organization, Fernandez is likely to serve as depth arm at Triple-A Omaha for much of the 2025 campaign.

Castillo (adductor) will throw a bullpen session Tuesday, Alex Weiner of ArizonaSports.com reports.

Castillo exited his first Cactus League appearance Feb. 22 with left adductor tightness and hasn't pitched since. He's ready to ramp up his throwing again but it's not clear when he might be available to pitch in a game. Castillo is in camp as a non-roster invitee, and the injury likely eliminated any chance he had to make the Opening Day roster.

The Orioles reassigned Coleman to minor-league camp Monday, Jake Rill of MLB.com reports.

Coleman has seen big-league action in each of the past four seasons, accruing a 3.84 ERA and 1.37 WHIP across 93.2 innings between stops with the Royals and Astros. The right-hander made all but one of his 37 appearances at the Triple-A level as a member of the Houston organization in 2024 and will likely spend the majority of the 2025 campaign with the Orioles' top affiliate in Norfolk.

Graveman (back) will throw a live batting practice session Tuesday, Alex Weiner of ArizonaSports.com reports.

Graveman was cleared to face hitters after throwing a 22-pitch bullpen session over the weekend. The veteran reliever is on the mend from a back injury and would appear close to making his Cactus League debut if he continues to progress. It's not yet clear whether he'll have time to be ready for Opening Day.

Pivetta tossed three scoreless innings in a Cactus League game against San Francisco on Sunday, allowing one hit and issuing one walk while striking out three batters.

Pivetta breezed through his second appearance this spring, giving up just one hit (a double by Willy Adames). The veteran righty has been impressive in his first two Cactus League starts, hurling 5.2 scoreless frames while posting a 7:2 K:BB. Pivetta is penciled in as the Padres' fourth starter after signing with the organization on four-year deal in mid-February.
