MILWAUKEE -- For one weekend, Miller Park wasn't a house of horror for the Pittsburgh Pirates.
The Pirates entered Sunday's game with a 9-47 record at Miller Park since 2007. A 5-4 victory gave Pittsburgh its first series win against the Brewers in Milwaukee since June of last year. The Pirates took two of three in the weekend set.
"We are getting a little bit better," Pirates manager Clint Hurdle said. "We did some good things today, and we probably complicated the game for ourselves a couple different times as well. But we were able to play through it. We got on top and we stayed on top. It was a good way to finish the series and to win the series."
The Pirates have won 13 of 15 and are a season high 12 games over .500.
Rodriguez (6-2) gave up three earned runs on seven hits in five innings to earn the victory. He struck out four and didn't walk a batter. Jason Grilli pitched a scoreless ninth for his major league-leading 20th save.
Hurdle said Rodriguez struggled with his command throughout most of the game but managed to preserve a lead.
"It wasn't his best stuff," Hurdle said. "The only easy inning he had was the first. We had a chance to get out of the fifth inning with him not giving up any runs, but that didn't happen. It was a battle out there today for us. (Rodriguez) wasn't sharp but he got the job done. We will take that and move on."
Strong pitching and timely hitting have fueled the Pirates recent run of success.
"We've been doing a really good job together as a team," Rodriguez said through a translator.
Pittsburgh extended the lead in the third. Starling Marte led off with a double and later scored on a sacrifice fly by Garrett Jones. A two-out double by Alvarez plated two more runs, giving Pittsburgh a 4-0 lead.
Gallardo (3-5) labored through just four innings. He gave up four earned runs and five hits while striking out seven and walking two.
"It's definitely frustrating. I don't know how to explain it, really," Gallardo said. "It's just one of those weird days. You go out there and have pretty good command of all of your pitches but obviously the results aren't there."
Gallardo threw 94 pitches over four innings.
"There were a lot of pitches," Brewers manager Ron Roenicke said. "But I thought his stuff was good. Good live fastball. I thought he was down in the zone with it, but he threw a lot of pitches. They fouled a lot of balls off. It's just surprising when I think he has good stuff and he struggles to get through four innings."
The Brewers rallied in the fifth. Rickie Weeks had a lead-off single. After Rodriguez retired the next two batters, Norichika Aoki singled up the middle and Jean Segura reached on an infield hit, loading the bases. Ryan Braun followed with a three-run double, cutting the Pirates lead to 4-3.
The Pirates added a run in the sixth on Marte's sacrifice fly.
Mercer had three hits and a stolen base for the Pirates.
The Brewers on Sunday selected the contract of right-handed pitcher Donovan Hand from Triple-A Nashville. Hand pitched two innings in his major league debut. Hand filled the roster spot of closer Jim Henderson, who was placed on the 15-day disabled list Saturday with a right hamstring strain. Hand's parents and brother drove from Alabama to attend the game. "My dad has dreamed of this for all his life. He wouldn't miss it for the world." ... Pittsburgh's Andrew McCutchen, who had two hits Sunday, has hit safely in 13 of his last 14 games at Miller Park.
