The Padres signed Acosta to a one-year contract Monday.
Acosta has never pitched in the big leagues but received a major-league deal from the Padres after holding a 2.42 ERA and 72:27 K:BB over 52 innings across three minor-league levels in the Nationals organization in 2025. The 27-year-old has minor-league options remaining and will likely begin the 2026 season at Triple-A El Paso.
