Lourdes Gurriel Jr. led the Arizona Diamondbacks to a 10-8 victory over the Miami Marlins with a pivotal three-run double in the seventh inning, contributing to a four-run rally that secured the win. Gurriel finished the game 2-for-2 with four RBIs, and his performance helped the Diamondbacks sweep the three-game series while improving their record to a major league best 31-13 since July 1. The Diamondbacks initially trailed 6-3 after a four-run fourth by Miami, highlighted by Jake Burger's two-run homer. However, Arizona surged back with key hits from Gurriel, Josh Bell, and Geraldo Perdomo, who also homered. The win went to Dylan Floro, while Justin Martinez recorded his fifth save despite a tense ninth inning where Miami loaded the bases. The loss further deepened the Marlins' struggles, marking their sixth defeat in seven games, leaving them at 46-81 for the season.
