Watch Red Sox’s J.D. Martinez Blast Grand Slam Off Yankees’ Masahiro Tanaka

BOSTON — J.D. Martinez needed just one pitch to make a pretty big stamp on the Boston Red Sox’s rivalry with the New York Yankees.

With Boston down 8-2 in the bottom of the fifth inning Wednesday evening, the Sox slugger crushed his sixth career grand slam, blasting a Masahiro Tanaka first-pitch splitter into the center field bleachers.

Take a look:

What a moment.

It was Martinez’s second home run in a Red Sox uniform, and it pulled Boston within a pair. Not only that, it was a huge momentum builder, as the Sox trailed by as many as seven in the game and the dinger brought plenty of life to both the team and the crowd.
