ATLANTA -- As Jeff Francoeur exited the indoor batting cages and headed toward his locker approximately 20 minutes after Friday night's series-opening loss to the Diamondbacks, he was clearly agitated. Instead of displaying his usual smile, the Braves right fielder was displaying nothing but pure frustration.

Less than 24 hours later, there was no need for Francoeur to make another postgame trip to the batting cages. Instead, he might have been better served to visit the Braves' trainers to see if he obtained any damaging bruises when he was mobbed by his teammates at the end of Saturday afternoon's 3-1 win over the Diamondbacks at Turner Field.

An already memorable homestand got a little sweeter for the Braves when this latest victory came courtesy of Francoeur's walk-off two-run homer against D-backs reliever Chad Qualls. An afternoon filled with great pitching was ended by a hitter who has been feeling anything but great recently.

"Something like this was nice for me," said Francoeur, whose only previous career walk-off homer came on May 13, 2006, against the Nationals. "Hopefully, I can enjoy it, and hopefully, this is something that gets me going here and gets me back to being relaxed at the plate."

When Jorge Campillo was forced to leave after four scoreless innings because of a blister that has bothered him since Tuesday's start, Braves manager Bobby Cox certainly wasn't relaxed. Then, when a controversial seventh-inning call by second-base umpire Jim Reynolds allowed the Diamondbacks to score their only run, the veteran skipper had less reason to feel at ease.

But with the game tied at 1, Cox might have provided a calming influence when he casually asked Francoeur if the wind was too strong for a highly hit ball to make it over the right-field wall. At the time, the veteran skipper was thinking about whether to let Chipper Jones swing if he gained a 3-0 count.

Francoeur indicated that the wind was too strong, and then after Jones reached with a leadoff single, he proved that it wasn't. Just hoping to put one of Qualls' good sinkers in play, the right fielder instead lofted a moon shot that landed just over the left-field wall.

"It's ironic that we talked about it, and [Francoeur was] the one that did it and not Chipper," said Cox, whose team has won seven of the first nine games of this season-long 11-game homestand.

This has been an eventful week for Francoueur, who has hit two of his five homers since Tuesday, when he ended his Major League-best streak of 370 consecutive games played. The elation he felt when he returned Wednesday with a three-hit game was erased when he went hitless in eight combined at-bats on Thursday and Friday.

All that resulting stress, which was actually a product of him hitting just .216 in his previous 22 games entering Saturday, was gone by the time Francoeur rounded third and headed toward the plate to meet his awaiting teammates. Everything was going well until he botched the helmet flip that he performed just a few steps from the plate.

"I was a little embarrassed, because I always love the helmet flip, but I had so much pine tar on my hand that [the helmet] went behind me," Francoeur said. "[Mark] Kotsay got some good body shots in. I'll let [my teammates] knock the crap out of me any day that I do that."

While there wasn't any need for Francoeur to receive of medical attention, Campillo, who surrendered just two hits in four scoreless innings, was evaluated by the trainers when the blister on his right middle finger grew too deep.

Since Thursday, the Braves have been concerned about this blister and even toyed with thoughts of promoting Charlie Morton from Triple-A Richmond to make just this one start. But after seeing Campillo limit the Mets to three hits in six innings on Tuesday, they frankly wanted to see him again.

"He wanted to try one more [inning], but if we [let him], he probably wouldn't pitch again for another three or four weeks," Cox said of the right-hander, whose only previous career start before Tuesday had come in 2005. "He was just outstanding today."

Across the way in the other clubhouse, Diamondbacks manager Bob Melvin could say the same about Randy Johnson, who allowed one earned run and five hits in six innings. This was the 44-year-old left-hander's first start at Turner Field since May 18, 2004, when he victimized the Braves with a perfect game.

While he wasn't perfect on this afternoon, he was dominant while registering a season-high 10 strikeouts. He stands 12 wins away from joining reaching the 300-wins milestone.

"He was just phenomenal," Francoeur said. "If he keeps pitching like that, there's no reason he won't win 300 games. It's just a matter of time before he does."

The lone run scored against Johnson came after Gregor Blanco -- the only left-handed hitter in the Braves' lineup -- tripled and scored on a Yunel Escobar third-inning single. The Diamondbacks tied the game in the seventh when Justin Upton scored on an Augie Ojeda RBI single.

Two batters earlier, the Braves thought they had Upton retired on a force play at second base and again when he fell off the second-base bag. Cox argued with Reynolds and then again in the eighth with first-base umpire Gary Cederstrom, who called Yunel Escobar out for interference after a sacrifice-bunt attempt.

But because he avoided adding to his career ejections total, Cox was on the field a short time later to enjoy the fact that Francoeur beat the wind and the Diamondbacks with one swing.

"Francoeur came up [big]," said Blaine Boyer, who was credited with the win. "That's what he's supposed to do. He's our leader."
