BOSTON (AP) – The Houston Astros have knotted the AL Championship Series at two games apiece by finally regaining their hitting stroke. The Astros erupted for seven runs in the ninth inning to come away with a 9-2 thumping of the Red Sox. It was a 2-2 game until Jason Castro’s RBI single opened the floodgates. Michael Brantley broke it open with a three-run double before Yordan Alvarez, Carlos Correa and Kyle Tucker followed with RBI singles to empty Fenway Park. The Red Sox managed just five hits and failed to score after Xander Bogaerts belted a two-run homer in the first inning. Alex Bregman homered for the Astros, who are guaranteed a Game 6 at home. Game 5 is Wednesday in Boston.
