Milwaukee Brewers third baseman Aramis Ramirez succinctly summed up his team's first trip of the season.

"We're doing everything right. That's why we're winning," Ramirez said.

The Brewers continued to do whatever it takes to win Thursday night, pulling away from Philadelphia for a 6-2 triumph to complete a 6-0 trip that began with a three-game sweep in Boston.

In boosting their overall record to 7-2, the Brewers completed their first undefeated trip of at least six games since they went 7-0 in San Francisco and St. Louis coming out of the all-star break in 2008. They are off to their best start since they went 7-2 to open the 1998 season.

"Let's keep it up," said Brewers manager Ron Roenicke. "Great pitching again, big hits. The bullpen is coming in and doing a great job. Everything is working."

The Brewers batted .320 (78 for 244) on the trip and scored 42 runs, compared to their .184 average and four runs in the season-opening series against Atlanta. They lead the major leagues with a 1.95 earned run average, including the best bullpen ERA (0.98).

It's not going to be easy to play better than this, and the Brewers won't have to do so to have a banner season. They compiled 38 hits in the three games against the Phillies and outscored them, 25-10, dominating the series.

"It was a pretty good road trip," said starter Marco Estrada, who out-pitched Philly ace Cliff Lee with six strong innings (five hits, two runs, two walks, six strikeouts). "To go in to Boston and sweep the 2013 champs, that was a great series. And to come in against Philly, a tough team, and do the same, it was just well-played overall.

"It's the way you want to do it. We're hitting; we're pitching. It's a little tougher to do on the road, but we did it. It just shows you what kind of team we have. We're a pretty good team."

The Brewers knew they'd have their hands full with Lee even though he had been less than sharp in his first two outings (21 hits in 12 innings, 6.00 ERA). When Lee struck out the side in the second and Marlon Byrd gave him a 1-0 lead in the bottom of the inning with a booming homer off Estrada, the Brewers faced a stiff test.

Ryan Braun (10 RBI in the series) continued to frustrate the renowned Philly boo-birds with a leadoff single in the fourth inning and raced around to score on Ramirez's ringing double to center. Khris Davis, who drove in two of the three runs Lee allowed in six innings, singled to right to put the Brewers ahead to stay.

As they did throughout the trip, the Brewers tacked on late runs to pull away. Carlos Gomez (3 for 5) continued his road rampage (.452 batting average) with an RBI single in the seventh, followed by another run-scoring hit by Jean Segura and Braun's sacrifice fly.
