BOSTON (AP) – The Boston Red Sox appear to have stumbled on a formula for beating the Houston Astros. The Red Sox grabbed an early 9-0 lead for the second straight game, hit another grand slam and throttled the Astros, 12-3 to take a two-games-to-one lead in the AL Championship Series. Kyle Schwarber hit Boston’s third slam in two games, highlighting a six-run second. The Sox are the first team with three slams in a postseason series. J.D. Martinez and Rafael Devers homered again after belting grand slams on Saturday. Christian Arroyo added a two-run blast in the rout. Boston starter Eduardo Rodriguez picked up the win after allowing five hits in as many innings, including Kyle Tucker’s three-run homer. Losing pitcher Jose Urquidy was chased in the second. Game 4 is Tuesday at Fenway Park.
