Phillies 12, Braves 11: Four Phillies walked with the bases loaded during an eight-run seventh inning, and host Philadelphia rallied to beat Atlanta.
Raul Ibanez added a two-run homer, helping the defending World Series champions overcome a 10-3 deficit and avoid a three-game sweep.
Brian McCann and Jordan Schafer hit two-run homers for the Braves, and Javier Vazquez left with a seven-run lead after pitching six effective innings in his first start with his new team.
But the Phillies rallied against Atlanta's bullpen in the seventh, when three straight batters walked to force in runs. Jorge Campillo walked in Chase Utley to force home the tying run, and Ryan Howard's slow grounder to first scored Jimmy Rollins and gave the Phillies their first lead of the season, 11-10.
