Rockies optioned RHP Eiberson Castellano to Triple-A Albuquerque.

Castellano earns a ticket back to the minors after picking up a three-inning save during Colorado’s 23-9 bludgeoning of the Athletics on Sunday afternoon. The 25-year-old looked sharp in his big-league debut and should get a more extended look with the Rockies in a couple weeks.

Eiberson Castellano allowed no runs over three innings of work to earn a save against the Athletics on Monday.

Yep, a save in a 14-run game. Castellano scattered four hits allowed and didn’t walk anyone while striking out two. If the Rockies get another 14-run lead, he could get another save.

Rockies selected the contract of RHP Eiberson Castellano from Triple-A Albuquerque.

Castellano will be making his major league debut. The 25-year-old former Phillies prospect was signed by the Rockies over the winter after becoming a minor league free agent. He had a 2.44 ERA in 10 starts for Double-A Hartford and one six-inning relief appearance for Albuquerque.

Rockies reassigned LHP Sean Sullivan, LHP Konner Eaton, LHP Adam Laskey, OF Drew Avans, RHP Eiberson Castellano and C Kyle McCann to minor league camp.

No major surprises among this batch of cuts, though Sean Sullivan showed out well during Cactus League play and likely put himself in a position to earn his first promotion to the big leagues at some point in 2026 when the Rockies need another starter.

Rockies signed RHP Eiberson Castellano to a minor league contract.

Castellano was shipped back to the Phillies last spring after the Twins made him the ninth overall pick in the offseason Rule 5 Draft. The 24-year-old reliever posted a pedestrian 5.14 ERA (4.18 FIP) and 24.2 percent strikeout rate over 35 innings over 20 appearances for Double-A Reading last season. He’s a low-risk dice roll for Colorado’s new-look front office.

Twins returned RHP Eiberson Castellano to the Phillies.

Castellano heads back to Philadelphia after being unsuccessful in a bid to make Minnesota’s season-opening bullpen mix. The 23-year-old righty was ninth pick in the offseason Rule 5 Draft after posting a 3.99 ERA across 22 appearances (20 starts) last year in the minors.

Dan Hayes of The Athletic reports that the Twins have informed Eiberson Castellano he won’t be a part of the Opening Day roster.

Castellano was the Twins’ Rule 5 draft pick, and Minnesota obviously didn’t feel comfortable with carrying him on the roster throughout 2025. Minnesota can try and work out a trade with the Phillies — the team the Twins selected Castellano from — but if not, he’ll be returned to the organization.

Twins selected RHP Eiberson Castellano from the Phillies with the ninth pick of the 2024 Rule 5 draft.

Castellano is a 23-year-old right-hander who reached Double-A last year, and he forged a 3.99 ERA in 22 appearances — 20 starts — with an impressive 136/29 K/BB over 103 2/3 innings. His starting background may be the long-term play, but he’ll obviously need to be a bullpen piece if he’s going to make the Twins in 2025.
