The Hokkaido Nippon-Ham Fighters have officially announced the release of 27-year-old infielder Rodolfo Castro following the conclusion of the 2026 NPB season. After signing in January 2026 with high expectations as a versatile switch-hitting power bat, Castro’s time in Hokkaido comes to an end after just one season.
2026 Season Overview: Highs and Lows in Hokkaido
Castro made an immediate impact upon arriving in Japan, homering in his NPB debut on opening weekend. However, consistency at the plate proved elusive over the course of the long campaign. While he demonstrated raw power with 8 home runs, strikeout issues and lower overall contact rates saw his top-team (Major) opportunities diminish in the second half of the season.

Release and Future Outlook
“On November 3, 2026, Nippon-Ham officially confirmed that Castro will not be offered a contract for the 2027 season, making him an unconditional free agent.”
Following off-field distractions and internal roster decisions during the postseason, the Fighters chose to part ways with the Dominican infielder. Now a free agent, potential next steps for Castro include:
- North American Comeback: Pursuing minor league deals (Triple-A) with MLB Spring Training invitations for 2027.
- Other International Circuits: Exploring opportunities in the KBO (Korea) or Mexican League (LMB).
- Winter Ball / Free Agency: Resetting his market through Winter League appearances in the Caribbean.
