The Dodgers struck back in convincing fashion Saturday night, scoring five runs in the ninth inning, capped by a three-run homer by Joc Pederson, to beat the Astros, 6-2, in Game 4 of the World Series to pull even at two games apiece. Houston suffered its first loss at home in the postseason this year (7-1), and the ninth inning represented the first time the Astros had trailed at home in the postseason in 71 innings.
