LOS ANGELES — Chad Pinder belted a game-tying, three-run home run in the seventh inning and Sean Murphy hit a go-ahead sacrifice fly in the eighth as the Oakland Athletics kept their season alive Wednesday by rallying for a 9-7 victory over the Houston Astros in Game 3 of the American League Division Series at Dodger Stadium.Oakland closer Liam Hendriks (1-0) pitched the final three innings to earn the victory, giving up no runs and one hit. He struck out four without issuing a walk. Hendriks pumped his fist behind the mound when Michael Brantley flied out to left field for the last out.On a day when the A’s hit five home runs, Murphy’s ball that stayed in the park was the difference as Oakland rallied from a 7-4 deficit to see another day in the best-of-five series.The teams combined to hit seven home runs and have 18 combined in the series on three consecutive day games, all with a first-pitch temperature of 81 degrees or higher.The A’s tied the game three batters into the seventh inning. Marcus Semien and Tommy La Stella singled before Pinder hit a home run over Dodger Stadium’s short wall in right field.Oakland went ahead in the eighth with two sacrifice flies. Murphy hit the first to score Robbie Grossman for an 8-7 lead, and Pinder hit the second. Pinder’s sac fly came one batter after La Stella left the game after getting hit in the left forearm by a Brooks Raley pitch.The A’s also got solo home runs from La Stella, Mark Canha, Matt Olson and Semien.The Astros received home runs from Jose Altuve and Aledmys Diaz.For the third time in three games, the A’s scored first, getting La Stella’s homer in the top of the first inning. Altuve answered in the Astros’ half of the first with his own solo blast, and Houston added a second run in the inning on a Carlos Correa fielder’s choice.
