In the eighth inning, Mookie Betts threw Tony Kemp out from right field, as the outfielder attempted to stretch a single in to a double. The two-run differential stings for Houston, who had a two-run home off the bat of Jose Atluve wiped away when a fan appeared to push Betts' glove on his leaping attempt. After a three-minute review, the designated hitter was called out, keeping the game at 2-0 in favor of Boston.
Jackie Bradley Jr. went deep for a second straight night and now has eight RBI in the series, including a clutch grand slam in Game 4. The Red Sox are now 4-0 on the road this Postseason, earning two wins in New York in the ALDS, and now two in a row at Minute Maid Park.
Rick Porcello struggled in the start for the Red Sox, giving up four runs on seven hits over four innings, including a big blow early on from Carlos Correa. The young shortstop had three hits and four RBI in the loss for the Astros, which took four hours, 33 minutes. For Boston, Rafael Devers and Xander Bogaerts had two RBI apiece, while J.D. Martinez singled home a run to extend the Red Sox lead late.
The Astros had to pull starter Charlie Morton early after he gave up three runs on three hits and two walks over 2.1 innings. They will have their ace, Justin Verlander, on the hill for Thursday's Game 5 against a struggling David Price, as Houston hopes to extend the series back to Boston.
