Professional career

Philadelphia Phillies

Castellano signed with the Philadelphia Phillies as an international free agent on July 2, 2018.[1] He did not pitch at all during the 2019 season, then was unable to pitch in 2020 due to the cancellation of the minor league season because of the COVID-19 pandemic.[2] Castellano finally made his professional debut with the Aguilas del Zulia of the Venezuelan Professional Baseball League later that year.[3] Castellano made his affiliated debut in 2021 with the Dominican Summer League Phillies White, posting a 1.09 ERA in 33 innings of work. He was promoted to the Clearwater Threshers of the Single-A Florida State League for the 2022 season, where he would record a 3.51 ERA in 51+13 innings of work. Returning to Clearwater for the 2023 season, Castellano's results backed up, with his ERA ballooning to 5.04 in 50 innings of work.[3]

Castellano began the 2024 season with the High-A Jersey Shore BlueClaws of the South Atlantic League before being promoted to the Reading Fightin Phils of the Double-A Eastern League in July.[1] It would be a breakout season for him, as he'd work to a 3.99 ERA over 22 appearances between both levels, while also being the system's Minor League Pitcher of the Month for July.[1] For his efforts, he'd be named the pitching winner of the Paul Owens Award for the 2024 season.[1]

On December 11, 2024, Castellano was selected by the Minnesota Twins ninth overall in the Rule 5 draft.[4] On March 25, 2025, Castellano was returned to the Phillies organization.[5] He made 21 appearances split between Jersey Shore and Reading, posting a 4-3 record and 6.44 ERA with 39 strikeouts across 36+13 innings pitched. Castellano elected free agency following the season on November 6.[6]

Colorado Rockies

On December 5, 2025, Castellano signed a minor league contract with the Colorado Rockies.[7]
