Diamondbacks Win 8-4 Over Mariners on Naylor 11th-Inning Grand Slam

Josh Naylor delivered a game-ending grand slam in the 11th inning to lead the Arizona Diamondbacks to an 8-4 victory over the Seattle Mariners, ending a three-game losing streak. The Diamondbacks had a 4-0 lead entering the ninth inning but lost closer Justin Martinez to right elbow tightness, which led to the Mariners tying the game with a two-run homer by former Diamondback Dominic Canzone. Merrill Kelly pitched six shutout innings, extending his scoreless innings streak to 15, while Naylor finished with three hits, five RBIs, and a walk, breaking out of a 2-for-21 slump. The Mariners' starter, Emerson Hancock, gave up a leadoff homer to Corbin Carroll, who also made a key sliding catch in the 11th inning. After the Mariners tied the game, Diamondbacks relievers Juan Morillo and Jalen Beeks shut down Seattle in the 10th and 11th innings, setting the stage for Naylor's dramatic walk-off grand slam off pitcher Carlos Vargas. This win improved Arizona's record to 32-34 and halted their recent skid during their six-game homestand.
