Red Sox - 100 001 01x - 3 9 0 Astros - 010 040 03x - 8 12 1Colby Rasmus's grand slam with two outs in the fifth inning off Clay Buchholz (5.2-6-5-1-6, 106) snapped a 1-1 tie. Buchholz had two outs and a runner on first when he allowed a single to George Springer and then hit Carlos Correa. Rasmus then went deep for his sixth home run of the season.
The Red Sox came right back, bringing the potential tying run to the plate with one out in the top of the sixth. But they could score only one run, as Brock Holt hit a sacrifice fly to left. The weak-hitting Chris Young (who would be pinch-hit for in his next at-bat) grounded to third to end the rally.
Dustin Pedroia and David Ortiz each had two hits for Boston.
