SAN DIEGO (Ticker) -- Mike Hampton has rediscovered his winning ways.

Hampton worked seven-plus strong innings to win his seventh consecutive decision and Chipper Jones hit his 300th career homer as the Atlanta Braves held on for a 5-4 victory over the San Diego Padres .

Hampton, who started the season 1-7, allowed three runs and seven hits en route to his latest latest win. The lefthander walked two and struck out three.

"I've just had so much more confidence," Hampton said. "If you lack it early (in the season), you start dwelling on it, and you just have to get back to basics. I think I've just been mixing up my pitches a little better."

"Hampton was very good," Atlanta manager Bobby Cox said. "He doesn't have a lot of pitches but I have confidence in him. He's been on a real roll."

Entering the eighth with a 5-2 lead, Hampton (9-8) walked Khalil Greene to start the inning and was relieved by Chris Reitsma , who gave up a single to Rich Aurilia before retiring the next two batters.

Closer John Smoltz came on for Reitsma and gave up back-to-back RBI singles to Brian Giles and Ryan Klesko that allowed the Padres to pull within 5-4. But he struck out Jay Payton to end the inning.

Smoltz worked around a single in the ninth to record his 30th save in 32 chances.

Jones led off the third by depositing a 3-2 pitch from San Diego starter Sterling Hitchcock (0-2) over the left field fence. It was Jones' fourth homer in the the last four games.

Jones' career home run total is the fifth most all-time among switch hitters.

"It's just another cool milestone," Jones said. "Hopefully, I can stay healthy enough to shoot for 400. I feel like I'm on the fastball and doing with it what I should."

Hitchcock allowed four runs and six hits in 6 1/3 innings. He struck out five and walked three in remaining winless in three starts this season.

"He was up early, but he did regroup and gave us a good effort there," Padres manager Bruce Bochy said. "He got locked in after those home runs, and pitched very well after that."

Andruw Jones opened the scoring with a home run to center in the second, marking the second time in three days that both Chipper and Andruw Jones have homered in the same game. Hampton added an RBI double later in the inning, giving Atlanta a 2-0 lead.

"The long ball beat us," Bochy said. "We just couldn't keep the ball in the ballpark. They've got a lot of power over there, and we made some mistakes and paid for them."

San Diego lost for the seventh time in its last eight home games while the Braves won their sixth straight on the road.
