The night began with Atlanta holding a two-game lead over San Diego, which played San Francisco.
Manuel, who is trying to maintain a delicate balance between resting some players for the postseason and continuing the momentum for his hot team, started six regulars.
"I can't imagine playing any game you didn't want to win," he said beforehand. "If we want to give some guys a rest, that's understandable. But I always think you should put a team on the field with the intention of winning the game on that day."
Although they are likely to face Cincinnati, the Phillies remained uncertain about their opponent for the National League Division Series, which begins Wednesday at Citizens Bank Park.
Before Rollins broke open the game, the Phillies gave righthander Kyle Kendrick a 2-1 lead on four singles in the fourth inning. Raul Ibanez and Carlos Ruiz had the RBIs. Ruiz went 3 for 5 to boost his batting average to a team-best .302. He is trying to become the first Phillies catcher to bat .300 since Mike Lieberthal in 2003 and only the second catcher to do so since Smokey Burgess hit .368 in 1954. He also could become only the fourth catcher to lead the Phillies in hitting since 1971.
Kendrick was pulled for pinch-hitter Domonic Brown in the Phillies' big sixth inning after allowing two runs over five. Brown had the go-ahead RBI when he drew a bases-loaded walk during a quality at-bat before Rollins launched his third career grand slam on the first pitch by reliever Mike Dunn to make it 7-2.
As he tries to find his stroke before the postseason, Rollins was expected to see more at-bats than any of the other Phillies regulars during this final weekend of the regular season. Rollins returned to the lineup Sunday after missing 14 games following a right hamstring injury on Sept. 8. The shortstop also has had two stays on the disabled list and has missed 74 games overall as a result of injuries.
Kendrick, who was likely making his final start of the season, had two of his best games at Turner Field earlier in the season. He pitched eight scoreless innings and allowed four hits on April 20 but got no decision in a 4-3 loss. He gave up one run and five hits over seven innings on June 2, but had no decision in the 2-1 defeat.
