Pinch-hitter Jason Heyward broke an eighth-inning tie with a three-run homer and the Los Angeles Dodgers rallied for a 6-3 victory over the reeling Seattle Mariners. Heyward lined a high 99 mph fastball from All-Star closer Andrés Muñoz over the short wall in the right-field corner to give the Dodgers their first lead. It was his second pinch-hit homer this season and the third of his career. Will Smith got aboard with one out when he was hit by a pitch, and Max Muncy walked. Muncy and Gavin Lux both homered for the second consecutive game. The NL West-leading Dodgers have won three straight and four of five.
