The Seattle Mariners broke open a tied game with five runs in the second inning and held off the Boston Red Sox for a 9-6 win at Fenway Park. Bryan Woo provided the foundation, striking out seven across six innings and keeping Boston from building sustained pressure early. Lazaro Montes and Randy Arozarena each homered, giving Seattle the offensive separation it needed before the Red Sox mounted a late challenge.

Seattle scored once in the first, then turned the game with its five-run second inning. Montes went 2-for-4 with a two-run home run and two runs scored, while Arozarena delivered a three-run homer despite finishing 1-for-5. J.P. Crawford added two hits and an RBI in three at-bats, giving the Mariners another consistent presence in the middle of the lineup. Seattle added one run in each of the third, fourth and fifth innings to build a 9-1 lead before Boston's late push.

The result moved Seattle to 65-74 and Boston to 75-64, with the Mariners taking a road win by controlling the middle innings and avoiding a decisive bullpen collapse. Boston's late four-run response showed enough offense to keep the game competitive, but the six-run deficit created by the second inning was too large to erase. Seattle leaves Fenway with a firm formula for the next stretch: get length from Woo, force early damage and make the opponent chase the game.
