The Padres signed 27-year-old reliever Daison Acosta to a one-year deal, adding a high-velocity arm with strong minor league stats.

The San Diego Padres have signed 27-year-old right-handed reliever Daison Acosta to a one-year major league contract, adding him to their 40-man roster. Acosta, who has never pitched in the majors, posted a 2.42 ERA in 52 relief innings for the Washington Nationals in 2025, striking out 33% of batters. He throws a 94.5 mph four-seam fastball and has a strong ground-ball rate. The deal is likely a split contract with MLB minimum pay when on the roster, and Acosta retains full minor league options. The signing reflects the Padres’ strategy of acquiring low-cost, high-velocity bullpen depth.
