"The Braves seldom have team meetings, especially not the players-only kind. Yet they called one on Friday after stumbling through a home series loss against Washington that put a serious dent in their postseason goals.

After hearing David Ross, Billy Wagner and others say what the team needed to get back on track, the Braves went through the checklist during an impressive weekend sweep of the New York Mets.

Derrek Lee crushed a seventh-inning grand slam Sunday in a 6-3 win at Citi Field, completing the Braves' second road sweep of the season and providing a boost before their much-anticipated showdown at Philadelphia that starts Monday.

"That one felt good," said Lee, who hit a full-count, two-out home run off former Braves reliever Manny Acosta, blasting the pitch to the second seating deck in left field for one of the longest home runs at Citi Field. "I flushed it. It's always nice when you feel it come off the bat like that."

Lee's fifth career grand slam was just his second home run in 27 games for Atlanta. It turned a 2-2 tie into a comfortable lead, and Derek Lowe (14-12) and the Braves used it to take a 2-1/2-game lead in the National League wild-card race.

"You couldn't have asked for anything more when we came in here," said Lowe, allowing six hits and two runs in six innings and winning his third consecutive start. "We knew we needed to play better than we did against Washington in all phases.""
