Fielder hit his 40th homer and Gallardo pitched five strong innings to help Milwaukee complete a sweep of the Houston Astros with a 6-0 win on Sunday. Gallardo will be shut down the rest of the season to keep his innings down.
"To end on a good note is always good and got a win and finished the year off strong," said Gallardo, who was on a pitch count and would not have gone beyond the fifth inning. "I knew it was the last start."
Fielder, who came in tied with Albert Pujols with a majors-best 127 RBIs, hit a solo shot in the first and then set a club record in the fifth when he walked for the 100th time this season.
He set a franchise record when he recorded his 127th RBI with a sacrifice fly in the Brewers' win Saturday.
Hart and Gerut also homered Milwaukee as built a 4-0 cushion for Gallardo, hoping it was enough to get him through five innings in his 30th and last start of the season.
Fielder said that the early run support was big.
"Obviously, he settled in real nice," he said. "It's always good to give your pitcher a little cushion so he can relax out there and make his pitches."
Gallardo gave up a single and two doubles, struck out seven and walked three. It was the first sweep by Milwaukee of Houston since a three-game set last season from May 30-June 1.
"I had a pretty good changeup going, too. I was able to keep the hitters off balance," he said. "I go out there and give my team all I got for every start."
The 23-year-old right-hander threw 77 pitches and left after the fifth with Milwaukee ahead 4-0. He pitched 185 2/3 innings in his first full year of action. He missed most of last season with separate knee injuries.
"My number one thing was just staying healthy for the whole year," he said. "That was my No. 1 goal and go out there and get 30 or more starts."
Brewers manager Ken Macha said that finishing strong was a good way for Gallardo to go into the offseason and look ahead to 2010.
"He's got a tremendous upside," Macha said. "Hopefully, this is a step in the right direction."
Carlos Villanueva, Chris Smith and Mike Burns pitched scoreless relief to preserve the victory for Gallardo and help Milwaukee extend their winning streak to five games, their longest since a season high seven-game run from May 12-19.
The Astros lost their the seventh consecutive game and matched the longest losing streak of the season set on May 21-27.
Astros manager Cecil Cooper said that it's tough to win when you're not scoring.
"We're not swinging the bats well," he said. "Four runs in three days, that says it all."
Houston scratched out just two runs on Friday and Saturday and lost both games.
Felipe Paulino (2-10) extended his career-worst losing streak to six games. He gave up four runs and eight hits in six innings. Paulino walked two and struck out seven. He hasn't won since beating Detroit on June 27. The right-hander also failed to get any run support for his fourth consecutive start.
Milwaukee gave Gallardo a 3-0 lead in the first when Hart hit a two-run homer, his 12th, and one out later, Fielder drove a 3-2 pitch to dead center. Hart's last home run was July 27, but this was the first since being reinstated from the disabled list Sept. 8 after undergoing an emergency appendectomy on Aug. 2.
"He's got the power," Macha said of Hart. "He hit that thing to right center."
Gerut connected off Paulino in the fourth for his eighth homer of the season and fourth since being acquired from San Diego on May 21 for Tony Gwynn.
Gerut, who went 3-for-4, added a run-scoring double in the eighth.
