CHICAGO -- Aramis Ramirez spent nine years watching games from the home dugout at Wrigley Field. He enjoyed the view from the visitor's side much better Monday night.
Ramirez, who played for the Cubs from 2003-11, hit a two-run shot in the fifth and a solo homer in the ninth as Milwaukee beat Chicago for the sixth straight time.
"In the summer it's a great place to play baseball and be a hitter," Ramirez said of his old ballpark.

Ramirez's second homer followed a three-run shot by Ryan Braun that landed on Waveland Avenue, his NL-leading 35th of the season. Braun had four hits and five RBI.
Corey Hart followed Ramirez with another shot that reached Waveland, giving Milwaukee back-to-back-to-back homers for the first time since Sept. 9, 2007 at Cincinnati, when Rickie Weeks, J.J. Hardy and Braun began the game with home runs.
"I don't remember ever being a part of it other than the time we led off the game," Braun said. "It's not going to happen very often, so you try and enjoy that moment when it does happen."
The Brewers sent 14 batters to the plate and tacked on nine runs and eight hits in the ninth, finishing with a season-high 21 hits.
"Obviously in the ninth inning it got out of hand," Braun said. "But up until then it was a really close game, tightly contested."
Utilityman Joe Mather got the final out of the inning for Chicago, the first position player to pitch for the Cubs since Gary Gaetti on July 3, 1999.
"Fastball and a hanging curve, apparently," Mather joked when asked to describe his repertoire.
Carlos Gomez had four hits, including his 14th homer, and all nine Brewers in the starting lineup hit safely.
Marco Estrada (2-5) allowed three unearned runs over five innings and struck out eight. His only other victory this season came against the Cubs on Aug. 21, when he struck out nine in six innings.
Justin Germano (2-4) gave up five runs and 10 hits in five-plus innings and has lost to Milwaukee in two straight outings. He gave up seven runs in 4 2/3 innings against the Brewers in his last outing on Aug. 20.
"I made three mistakes that led to four runs," Germano said. "It's just hard to be perfect but I have to work on the mistakes that I make, or at least who I make them to."
All three ninth-inning homers came off Alex Hinshaw, who was pitching for the second time since being claimed off waivers from San Diego on Aug. 19.
Brett Jackson hit his third homer in four games and walked twice for Chicago. Alfonso Soriano added two doubles and drove in a run.
The Brewers improved to 18-5 against the Cubs since the 2011 All-Star break, while Chicago has dropped 19 of 25 overall since the July 31 trade deadline.
"[Cubs fans] also have to understand that it's a process and that the new front office came in with a plan and they're going to execute it," Ramirez said. "It's going to be painful. Right now they don't have a good product on the field. I'm pretty sure they're smart people. They have a good game plan going."
Milwaukee erased a two-run deficit on consecutive pitches in the fifth. Braun rolled a double just past the third base to score Weeks. Ramirez then clubbed Germano's first pitch into the bleachers in left to give the Brewers the lead.
Ramirez hit 239 homers in nine seasons during his time with the Cubs, but went 1 for 11 in his first series against his former team at Wrigley Field on April 9-11.
Ramirez, who is 8 for 16 with eight RBI over his last four games, added an RBI double, his major league-leading 43rd double of the season.
"He's hitting the ball every night," Brewers manager Ron Roenicke said. "He's hitting the ball. It's fun to watch."
Jackson, Chicago's rookie center fielder, hit his fourth homer leading off the sixth off Kameron Loe to cut the lead to 5-4.
