The San Diego Padres announced the release of veteran outfielder Nick Castellanos following a disappointing performance in which he batted .191 with an OPS of .560 over 39 games. The decision came after Castellanos was designated for assignment earlier in the week, during which the team had a week to trade him but opted for outright release instead, covering his remaining veteran minimum salary. Manager Craig Stammen noted that Castellanos struggled with his role on the bench and had personal matters affecting his performance. Team leader Manny Machado expressed surprise and disappointment over the move, stating that the players were devastated by the decision and emphasizing that Castellanos was not responsible for the team's offensive struggles. This marks Castellanos' second release this year, having previously been let go by the Philadelphia Phillies, who paid him nearly $20 million to part ways. The Padres are also making other roster changes, including placing right-handed pitcher Jeremiah Estrada on the injured list due to knee soreness and recalling David Morgan from Triple-A, while Jhony Brito was reinstated from the 60-day injured list and optioned back to Triple-A. Ramón Laureano was transferred to the 60-day injured list after undergoing season-ending surgery.
