Miller struck out two batters in two innings as the Cleveland Indians won Game 4 of the World Series to take a 3-1 lead over the Chicago Cubs.
The left-hander has pitched 17 innings in his nine appearances this postseason.
Miller finally gave up his first run of the playoffs Saturday, bringing his postseason ERA to 0.53.
