Orioles' Luis F. Castillo: Dropped from 40-man roster
Rotowire
The Orioles designated Castillo (undisclosed) for assignment Sunday.
Shortly after the Orioles claimed him off waivers from the Mariners on May 7, Castillo was placed on Triple-A Norfolk's 7-day injured list due to an unspecified injury. He made pair of rehab starts in the rookie-level Florida Complex League earlier this month and was reinstated from Norfolk's IL on Sunday, only to be simultaneously removed from the Orioles' 40-man roster to make room for right-hander Matt Bowman, whose contract was selected from Triple-A.

Orioles' Luis F. Castillo: Yet to debut for new organization
Rotowire
Triple-A Norfolk placed Castillo on its 7-day injured list May 13 due to an unspecified injury.
After being acquired from the Mariners on May 7 and claiming a spot on the Orioles' 40-man roster, Castillo has yet to make his organizational debut. He may have gotten hurt during his final appearance with Triple-A Tacoma on May 3, though any potential injury didn't prevent him from passing a physical before the trade was made official. Once he's healthy, Castillo should occupy a spot in the Norfolk rotation.

Mariners' Luis F. Castillo: Drawing another start
Rotowire
Castillo is scheduled to make his next start Wednesday versus the Astros in Seattle, Matt Kawahara of the Houston Chronicle reports.
Castillo made his Seattle debut and his first MLB start in San Francisco on Friday, when he struck out two and allowed three runs on six hits and six hits over three innings in a no-decision. While not overly impressive, Castillo's performance was good enough to earn him another turn through the rotation, but he likely won't be in store for an extended stay with Seattle. As soon as George Kirby (shoulder) completes a rehab assignment and is deemed ready to make his MLB season debut, Castillo will be the odd man out of the rotation, barring injuries to any of Seattle's other four starters.

Mariners' Luis F. Castillo: Inefficient in first start
Rotowire
Castillo allowed three runs on six hits and two walks while striking out two over three innings, taking a no-decision in Friday's extra-innings loss to the Giants.
Castillo's first major-league start was nothing to write home about. He allowed an RBI single to Matt Chapman in the first inning and a two-run double to LaMonte Wade in the second. Castillo finished with 39 strikes on 68 pitches and forced the Mariners to dip into their bullpen early, with all eight relievers getting action in this contest. Castillo's only other major-league experience came in 2022 with the Tigers, when he threw 3.2 innings scoreless innings of relief. The fifth spot in the Mariners' rotation remains unsettled until George Kirby (shoulder) is ready for his season debut, but if Castillo gets another turn, he's lined up to face the Astros next week.

Mariners' Luis F. Castillo: Contract selected for start
Rotowire
The Mariners selected Castillo's contract from Triple-A Tacoma, and he's scheduled to start Friday against the Giants.
The right-hander allowed one run over 5.2 innings during his lone start for Tacoma this year and will now get a look in the big-league rotation. Castillo's only major-league experience came with Detroit in 2022, when he delivered a 4:0 K:BB over 3.2 scoreless frames in three appearances. He spent the 2023 and 2024 campaigns pitching in Japan and had a 3.01 ERA across 143.1 innings before inking a minor-league deal with Seattle during the offseason.

Mariners' Luis F. Castillo: Sent out of big-league camp
Rotowire
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.
