The series started with Thursday's 4-3, 12-inning win that included blown saves by Ryan Madson and Brad Lidge and a walk-off home run by catcher Brian Schneider.
One night later, the Phillies rallied from six runs down in the bottom of the ninth, thanks to home runs by Greg Dobbs and Cody Ransom, and won, 9-7, on a Ryan Howard walk-off home run in the bottom of the 10th.
You have to go back to 1962 to find the only other time in Phillies history that the team won consecutive games on walk-off homers. The Phillies' six-run rally also marked the third time this season a team rallied from six runs down in the bottom of the ninth to win a game. That had never happened before in baseball history.
More history happened Saturday night when the sellout crowd witnessed a third straight walk-off victory when Rollins singled home Carlos Ruiz in the bottom of the 11th inning. It was the first time the Phillies had ever won three straight games in their final at-bat.
That win, of course, came after Reds lefthander Travis Wood pitched eight perfect innings before giving up a ninth-inning double to Ruiz. The Phillies' Roy Halladay, who already has a perfect game on his resumé this season, kept the pressure on the rookie by pitching nine scoreless innings.
As for the fan factor, the Phillies packed Citizens Bank Park for all four games - that sellout streak is up to 84 games - and the crowd was involved more than usual.
With two outs in the top of the 12th inning Thursday night, a fan caught a foul ball that Jayson Werth was in pursuit of, prompting a profanity-laced tirade from the Phillies rightfielder.
During Sunday's game, Ruiz sent a third-inning shot to left-center field that a fan reached over the railing to catch, prompting a video review by the umpiring crew. The call, initially made by second-base umpire Laz Diaz, stood as a double.
An inning later, Werth hit a shot to deep left-center that was caught by a fan with a glove. Diaz again correctly ruled it was a double.
"This game will consistently surprise you," Werth said. "You can never think you've seen it all because you definitely haven't."
