Diamondbacks End Three-Game Losing Streak with 11th-Inning Grand Slam over Mariners

The Arizona Diamondbacks defeated the Seattle Mariners 8-4 in an 11-inning game highlighted by Josh Naylor's walk-off grand slam after the Mariners rallied to erase a four-run deficit in the ninth inning. Arizona closer Justin Martinez exited the ninth inning due to injury after initially retiring two batters, leading to a Mariners comeback capped by Dominic Canzone's two-run homer to tie the game. Corbin Carroll and Naylor were key contributors for the Diamondbacks, with Carroll hitting a leadoff homer and Naylor finishing with three hits and five RBIs. Mariners starter Emerson Hancock allowed two runs over five innings, but Seattle has struggled recently, losing six of their last seven games. Jalen Beeks earned the win for Arizona by pitching a scoreless 11th inning, while the Mariners fell short despite multiple players recording two hits apiece. The victory ended Arizona's three-game losing streak and extended Merrill Kelly's scoreless innings streak to 15.
