Tom Glavine was much better with the Braves than he has been against them.

Andruw Jones broke out of a big slump with a homer and three hits, and Mike Hampton stayed unbeaten with another solid outing to lead Atlanta over the Mets 8-4 yesterday.

Wilson Betemit hit his first big league home run and Eddie Perez also connected for the Braves, who beat Glavine for the seventh time in eight tries since he left Atlanta three years ago.

“We just know what he’s going to do every time we face him,” Jones said.

After dropping the series opener, the Braves defeated Pedro Martinez and Glavine in less than 24 hours to take two of three from their NL East rivals. And that was without slugger Chipper Jones, who missed all three games with a bruised left foot.

“It’s a great comeback for us,” manager Bobby Cox said. “We beat two of the best, so we’re very pleased getting out of here with two out of three.”

Hampton (3-0) pitched seven effective innings against his old team, giving up home runs to Cliff Floyd and Doug Mientkiewicz. The left-hander improved to 14-1 with a 2.61 ERA since July 4.

Andruw Jones scored three times and finished a triple shy of the cycle, snapping a 3-for-47 slump. Raul Mondesi added a two-run single off Glavine (1-3), booed off the mound by Mets fans frustrated with his pitiful performances against Atlanta.

“I don’t go out there thinking about it,” he said. “It’s a challenge. They’re a good team, and they’re a team I haven’t pitched well against. As an athlete, it’s the kind of thing that drives you to do better. I have to start doing a better job of it.”

The two-time Cy Young winner spent the first 16 years of his career in Atlanta, then signed with New York before the 2003 season. Including the lat est meltdown, he is 1-7 with a 9.36 ERA in eight outings against the Braves, who are obviously plenty familiar with his paint-the-corners approach.

“There’s been times I’d say the same thing to him, but then I’d watch him be stubborn and win,” said Atlanta pitcher John Smoltz, a longtime friend and teammate. “I can’t imagine what he’s feeling right now facing us. I just know he wants to win very badly.”

Glavine gave up seven runs, 12 hits, and three walks in 4 1/3 innings, raising his ERA to 5.67.

“What you do in April doesn’t necessarily dictate what you’re going to do the rest of the year,” Glavine said. “I’m not going to say that I’m where I want to be right now. But I may not be as far off as other people think I am.”

Hampton, who pitched the Mets to the 2000 World Series,was much better. He allowed three runs and seven hits, striking out five.

“I’ve seen him pitch better than this,” Mientkiewicz said. “But he has good stuff and he’s not a guy you want to get behind in the count because he knows how to work it.”

Mientkiewicz connected with two outs in the second, giving the Mets a 1-0 lead.

The Braves caught a break in the third, when third base umpire Kerwin Danley called Andruw Jones’s hooking liner fair even though television replays appeared to show it landed foul. He wound up with a two-out double, and Mondesi punched the next pitch to center for a two-run single.

Betemit doubled leading off the fourth and scored on Rafael Furcal’s single. Brian Jordan added an RBI single, making it 4-1.

Floyd’s sixth homer of the season, a two-run shot in the fourth, extended his hitting streak to 14 games.

Perez hit a two-run homer in the fifth, and Betemit followed with a drive over the left-field fence to push the lead to 7-3 and chase Glavine.

Andruw Jones homered against Heath Bell leading off the seventh.
