John Gast (2-0) won his second straight start in place of the injured Jake Westbrook and fellow rookie Seth Maness escaped a bases-loaded, none-out jam in the seventh to help the Cardinals win for the 14th time in 17 games. They took two of three from Milwaukee and lead the season series 8-2.
Lohse (1-5) has lost all three of his starts against St. Louis after going 16-3 for the Cardinals last season and then leaving in free agency when they opted to go with younger players. He gave up four runs in six innings, and is 0-4 overall in his last five starts.
After getting one hit the first time through the order, the Cardinals jumped on Lohse for six hits in the first seven at-bats in the fourth. Yadier Molina singled for the lead and Jon Jay followed with an RBI double, both coming on first pitches.
Freese's opposite-field single through a drawn-in infield was his fifth RBI of the series after totaling four prior to the weekend, and Pete Kozma capped the rally with a perfectly-placed squeeze bunt that Lohse couldn't touch with a diving barehanded attempt.
Gast has opened with five scoreless innings in each of his first two career starts, and has allowed a total of six runs in the sixth. Fellow rookie Seth Maness took over with one out and runners at the corners, and the Brewers got two-out RBIs from Betancourt and Bianchi to cut the deficit to 4-2.
Maness finished with a unique pitching line, allowing no runs on five hits in 1 2-3 innings.
The Brewers opened the seventh with three straight hits and had two of their best hitters due up. Jean Segura, who entered with an NL-leading .361 average, popped up to first and Ryan Braun grounded into a double play started by Freese.
Aoki was barely run down at the plate by Freese to foil a double-steal attempt and end the first. The Brewers attempted to manufacture a run with Betancourt down 1-2 in the count while mired in a 3 for 40 slump and Freese faked a few tosses to the plate before flicking his glove to catch Aoki beginning his dive.
