Philadelphia — There have been a multitude of harsh losses to choose from this year, but the day the Braves season looked like it was finally lost came Sunday at Citizens Bank Park.

For the second day in a row, the Braves failed to hold a significant lead — this time of five runs — and lost 12-10 on a barrage of five Phillies home runs.

As the last two homers cleared the fences off the bats of Jayson Werth and Jimmy Rollins, Phillies fans broke out in a mock tomahawk chop.

But more demoralizing than any blow off a bat that was watching catcher Brian McCann leveled at home-plate on a helmet-to-helmet hit from Shane Victorino as he scored on a two-run single by Ryan Howard in the sixth inning.

McCann was knocked unconscious and suffered a mild concussion.

With McCann likely out for a few days at least and Chipper Jones possibly headed to the disabled list with his left hamstring, it was hard not to figure the third key bat in the Braves lineup — Mark Teixeira — is down to his last games in a Braves' uniform.

Manager Bobby Cox took Teixeira out with the Braves down by six runs at the end of the sixth inning.

The Braves mounted a five-run inning without them in the eighth to cut a 12-5 lead to 12-10 but it ended with Corky Miller's broken-bat grounder.

After winning the first game of this series 8-2 and leading 9-3 in the second, the Braves lost two out of three to fall to 2-10 against the Phillies this season.

The Braves are now 7 1/2 games behind the first-place Mets, and 7 1/2 games have never seemed so far.

When the Braves came out of the All-Star break with nine games to go against the Nationals, Marlins and Phillies, they were 6 1/2 games out. After dropping two of three series, they are one game worse.

They finished his six-game trip at .500 and almost leave GM Frank Wren no choice but to start selling off the pieces, though he was trying to give them the benefit of the doubt before Sunday's game.

"You see good things and bad things, I'd say at this time I'm seeing more good than bad, but the results are you've got to win," Wren said. "At the end of the day, it's all about winning."

At the end of the day Sunday, it felt all about losing.

"Easily could have been 5-1 and going 3-3 [on this trip] ... " Mark Kotsay said, and stopped to sigh. "We knew what we had to do this road trip, what we needed to have accomplished. We lost ground on this road trip, where we could have made ground. That's the reality. We were told we needed to win in order to add and we didn't get that done."

A near two-hour rain delay washed out starter Jorge Campillo, which left the Braves' bullpen exposed to the element.

Jo-Jo Reyes, who was scheduled to start Monday, came to the mound after the rain delay. He was spotted a 5-0 lead in the top of the fourth inning and couldn't make it stand up for a half inning. He gave five runs right back in the bottom of the inning on two home runs — a two-run shot by Chris Coste and a three-run shot by Victorino.

All five runs scored with two outs. Reyes paid dearly for two walks in the inning as both came around to score.

Kelly Johnson and Omar Infante had hit back-to-back homers in the fourth inning to put the Braves ahead 5-0.
