Down 2-1, the Astros turned the tables with three runs against the Red Sox's bullpen in the seventh. Colby Rasmus tied it with a pinch-hit homer against Alexi Ogando. Marwin Gonzalez (RBI double) and Evan Gattis (RBI single) put Houston in front with clutch hits against Junichi Tazawa.
The Red Sox bounced right back in the eighth. David Ortiz ripped a solo shot to right to make it a one-run game. Astros manager A.J. Hinch brought on closer Luke Gregerson for a four-out save, but Mike Napoli scorched an RBI double over left fielder Preston Tucker's head to tie it up.
