J.D. Martinez / Rafael Devers

J.D. Martinez and Rafael Devers became the first tandem in Postseason history to each launch grand slams in the same game. Martinez got the Boston Red Sox on the board first with a grand slam in his first at-bat of the contest. Devers followed up in the top of the second inning with a grand slam of his own. This combined effort led the way for the Red Sox 9-5, ALCS Game 2 victory over the Houston Astros.
