Boston Red Sox hit 2 grand slams in first 2 innings of ALCS Game 2; first team to do so in postseason

The Boston Red Sox quickly bounced back from their loss to the American League Championship Series opener. They hit two grand slams against the Houston Astros in just two innings.
According to ESPN Stats & Information, they were the first MLB team to achieve two grand slams during a postseason match.

In the first inning, the Red Sox began the offensive pile-on. J.D. was able to score after a Kyle Schwarber double, back-to-back walks by Rafael Devers (Alex Verdugo) and a Kyle Schwarber home run. Martinez scored a run off Houston's Luis Garcia, crossing the right-field fence to score Boston 4-0.

In the second inning, the Red Sox followed Garcia's injury with a Kevin Plawecki walked.

Houston brought in Jake Odorizzi as a pitcher. Red Sox second baseman Christian Arroyo hit a ground ball to right-field and Kik Hernndez hit a line drive to left-field. Devers hit a line drive homer to right field and Boston was up 8-0 at the end of the second.

ESPN Stats & Information research shows that only five teams have hit two grand slams within the first two innings of a regular season game. This includes the Los Angeles Dodgers.

Hernandez added to the offensive assault, hitting his fifth home run in five games in the fourth innings to make Boston 9-0. This homer was a follow-up to the Red Sox's outstanding performance in Game 1 when Hernandez hit two home runs, one double and one single.
