Adrian Del Castillo made a stunning entrance into Major League Baseball by hitting a walk-off home run in his second game, leading the Arizona Diamondbacks to a 3-2 victory over the Philadelphia Phillies. The 24-year-old catcher, filling in for the injured Gabriel Moreno, became the first player in Diamondbacks history to have his first career homer be a walk-off blast, thrilling a crowd of nearly 38,000 at Chase Field. Del Castillo's decisive hit came off All-Star reliever Jeff Hoffman and capped a game that saw the Diamondbacks secure their fifth win in six games, improving their record to 15-5 since the All-Star break. He finished the game with three hits and two RBIs, showcasing his potential in a crucial pennant race. Arizona's Ryne Nelson also delivered an impressive performance, pitching 7.1 innings with nine strikeouts while allowing just two runs. The Diamondbacks will look to build on this momentum as they continue their series against the Phillies.
