Broxton drove in the go-ahead run and saved a run with a leaping catch, Matt Garza made a strong start in his return from the disabled list, and Milwaukee beat the St. Louis Cardinals 2-1.
Broxton, who robbed Jose Martinez of a homer in the second when he stretched his glove atop the center field wall, gave Milwaukee a 2-1 lead with a single in the fifth off reliever Brett Cecil (1-4).
"It was awesome to be able to come out today and do something good for the team," Broxton said. "I'm just trying to make plays. That's my job. It's huge for my confidence, it's huge for the team's confidence. It's a win-win situation for everyone."
Garza (5-5), making his first start since July 21 because of a right leg strain, gave up one earned run on four hits in 5 2/3 innings to give second-place Milwaukee its first home series win over St. Louis since July 2012. The Brewers, trying to stay close to first-place Chicago in the NL Central, won for just the fifth time in their last 17 games.
