ATLANTA (Reuters) - The Philadelphia Phillies got their offense on track with an 8-3 victory over the Atlanta Braves Thursday.

The Phillies took a 5-0 lead after three innings, while 47-year-old Jamie Moyer pitched six innings and allowed two unearned runs to get the win.

"I'm kind of amused and amazed at how we handle things," Moyer (2-1) told reporters.

"It's an even keel, there's no real excitement. I like that. I think we handle things well as a team."

Atlanta starter Derek Lowe suffered his first loss of the season, allowing five runs and two walks in five innings.

Philadelphia scored twice in the first inning before adding three in the third, where Juan Castro had an RBI single and finished 3-for-5.

The Braves scored twice in the fifth on Phillies' throwing errors but the visitors replied with three late runs on two RBIs from Shane Victorino.

One day after Roy Halladay pitched a complete game shutout, Moyer followed with another strong pitching effort that silenced the Atlanta batting lineup.

The Braves did not record an earned run in the 23 innings pitched by the three Philadelphia starters during the series.

"It's worrisome," said Atlanta veteran Chipper Jones, who went 2-for-4. "We've got certain guys that are swinging the bat well, and certain sections of the lineup that are swinging the bat well and others that are just struggling right now.

"We've got to stand by them and help them get through this period."
