MLB roundup: Trevor Story's 3 HRs, 7 RBIs lead Red Sox's rout

Trevor Story went 4-for-4 with three home runs, seven RBIs and five runs as the Boston Red Sox beat the visiting Seattle Mariners 12-6 on Thursday night.

The Mariners led 4-0 through 1 1/2 innings, but Story's homers in the second and third innings helped the hosts tie the score. Boston added two runs in the sixth and three in both the seventh and eighth.

Story capped his second career three-homer and seven-RBI games with a three-run shot to left in the eighth. J.D. Martinez (4-for-5, three runs) and Alex Verdugo (3-for-5, four runs) also had big nights for the Red Sox, who logged season highs in runs and hits (16) on their way to a second straight win.

Julio Rodriguez (3-for-5) and Dylan Moore (four RBIs) both homered and Eugenio Suarez went 2-for-5 with two runs for Seattle. George Kirby (0-1) took the loss, allowing five runs on eight hits in five-plus innings.

Mets 7, Cardinals 6 (10)

Pete Alonso belted a walk-off two-run homer in the 10th inning for host New York, which posted a win over St. Louis hours after learning Max Scherzer would miss six-to-eight weeks with a left oblique injury.

The Mets took three of four from the Cardinals but lost Scherzer, who exited Wednesday's game in the sixth inning after feeling a "zing" in his left oblique. An MRI administered Thursday revealed a "moderate to high grade" strain. Alonso had three hits and three RBIs, and Jeff McNeil also knocked home three runs.

Colin Holderman (1-0) earned his first big league win despite giving up the go-ahead unearned run in the top of the 10th inning.

The Cardinals rallied from a pair of two-run deficits and tied the game in the ninth inning before going ahead in the 10th on a run-scoring double play by Albert Pujols. Paul Goldschmidt blasted his sixth
