MILWAUKEE — Maybe it was the sellout crowd. Maybe it was David Freese. Whatever it was, something lit a fire under the Brewers on Friday night at Miller Park.

After Freese led off Game 6 of the National League Championship Series with a home run to give the Dodgers the lead, the Brewers countered in a big way off Hyun-Jin Ryu, batting around to jump out to a 4-1 lead in the bottom of the frame. The four-run output was the largest in any inning this postseason for the Crew, which need a win to force a decisive seventh game.

MILWAUKEE — Maybe it was the sellout crowd. Maybe it was David Freese. Whatever it was, something lit a fire under the Brewers on Friday night at Miller Park.

Jesus Aguilar doubled and drove in two, Mike Moustakas laced an RBI double, and Erik Kratz plated Moustakas with a fourth run by rolling an RBI single into right off Ryu, who needed 31 pitches to escape the frame. Ryu had not allowed four earned runs in any of his 15 regular-season starts.

For the Brewers, the outburst marked a departure. They entered play having scored just three runs over their previous 22 innings, and just seven combined over the three games of this series in Los Angeles. Aguilar, Moustakas and Kratz came in particularly cold, combining to go 7-for-50 (.140) in the series prior to the inning. Aguilar and Moustakas were 0-for-8 with six strikeouts with runners in scoring position before that flurry, and Aguilar had been 0-for-5 with four strikeouts in those spots.

But that all changed after Lorenzo Cain led off against Ryu with an infield single, then advanced to second on a Christian Yelich grounder. Ryan Braun walked, setting up a two-on, one-out situation for Aguilar, who poked a double into the right-field corner. Moustakas then pulled a similar double to score Aguilar, scoring on Kratz’s opposite-field hit a batter later. Orlando Arcia followed by punching a single to left — the fourth consecutive hit off Ryu — before Miley flied out to end the frame.
