Why Padres DFA'd Nick Castellanos during homecoming series vs. Phillies

The San Diego Padres designated outfielder Nick Castellanos for assignment (DFA'd) during a series against the Philadelphia Phillies, his former team, making it a notable homecoming situation. The move was described as unsurprising given Castellanos' performance struggles with San Diego. The roster decision signals the Padres are moving on from the veteran outfielder during the current season.
