MILWAUKEE -- Jonathan Broxton knows the dangers of throwing high pitches on warm summer days at Miller Park.
He simply couldn't make the right pitch to Khris Davis.
Davis hit two home runs, including a two-run shot in the eighth inning off his former teammate, and the Brewers beat St. Louis 5-4 Sunday and ended the Cardinals' four-game winning streak.
Broxton (1-3), traded from Milwaukee to the NL Central leaders on July 31, relieved Kevin Siegrist with a runner on second and one out with a 4-3 lead. Davis hit the first pitch into the Cardinals' bullpen for his 11th home run.
"[When] the roof's open and the panels are open, the ball flies here," said Broxton, who pitched in 51 games for Milwaukee over 2014-15. "You really got to focus on getting the ball down. I didn't get that first pitch down. It's away, but it's just up."
Davis' fourth home run in four games overcame a big hit by Matt Carpenter. The Cardinals leadoff man hit a three-run home run off Milwaukee starter Jimmy Nelson with two outs in the seventh that gave St. Louis a 4-3 lead.
Carpenter has been sensational since returning to the leadoff spot in the Cardinals order on July 30. He has batted .375 with seven home runs, five doubles and 12 runs scored in 10 games.
"He looks a lot like we saw earlier in the season," St. Louis Manager Mike Matheny said. "I think it just proves to him that wasn't necessarily a fluke and what he's got to do to get back into that kind of groove."
Will Smith (5-2) pitched a scoreless eighth. Francisco Rodriguez worked the ninth for his 26th save in 26 chances this year.
Davis earlier hit a two-run home run off Cardinals starter John Lackey.
Last Thursday, Davis hit two three-run home runs in Milwaukee's 10-1 victory over San Diego. He had been held hitless in six at-bats during the first two games of this series, two shutouts for the Cardinals, before breaking loose.
Pinch-hitter Jason Rogers opened the Milwaukee eighth with a single off Siegrist. Shane Peterson's sacrifice bunt moved him to second, and Broxton took over.
Lackey gave up six hits, including a solo home run by Elian Herrera in the third and the drive by Davis, in six innings.
"It's a shame, that one bad inning," Matheny said. "A walk, a homer, he gave up next to nothing all day today. Sixty-six pitches. We didn't have a lot of offensive opportunities. That's tough. Throwing the ball that well and didn't get a lot of offensive support early."
Herrera's home run with one out in the third came one pitch after Jean Segura was caught stealing second base, a play that was confirmed after a challenge by the Brewers.
Jason Heyward hit an RBI single in the sixth for the Cardinals. Nelson allowed four runs on eight hits while striking out eight in seven innings.
Brandon Moss and Stephen Piscotty opened the St. Louis seventh with singles, and Tony Cruz's sacrificed. Pinch-hitter Mark Reynolds grounded out but, after a brief conference at the mound, Nelson stayed in the game and Carpenter hit his 16th home run.
