PITTSBURGH (Ticker) -- Oliver Perez endured a wild debut for the Pittsburgh Pirates .

Four days after being acquired from the San Diego Padres , Perez yielded three hits and three walks in a seven-run third inning as the Atlanta Braves rolled to a 13-6 victory over the Pirates.

Gary Sheffield singled home a run and Javy Lopez and Mark DeRosa each had two-run doubles in the third off Perez (4-8) before rookie Mike Hessman greeted reliever Nelson Figueroa with a two-run homer.

Coincidentally, Hessman was optioned to Class AAA Richmond right after the game, but will return when rosters are expanded in September. He was recalled on August 18.

Marcus Giles hit a solo homer off Figueroa to increase the lead to 8-1.

"It's nice to see the bats break out," said Marcus Giles . "We're capable of it and it's nice to see. We hadn't been swinging the bats well the last couple of days."

A three-run homer by Craig Wilson in the fourth inning and RBI singles by Jack Wilson and Jeff Reboulet in the seventh and eighth innings, respectively, pulled the Pirates within 8-6.

The single for Jack Wilson extended his hitting streak to 17 games.

But the Braves broke open the game again with five runs in the ninth against relievers Mike Lincoln and Mike Gonzalez . Sheffield had a two-run double for his third hit of the game and scored on a single by Chipper Jones . Andruw Jones followed with a two-run homer.

Braves rookie Horacio Ramirez (9-4) picked up his first win since July 7 despite allowing five runs and 10 hits in seven innings.

"He (Ramirez) made one bad pitch to (Craig) Wilson and he deposited it," said Braves manager Bobby Cox . "It was good to get seven innings out of him to give our bullpen a rest.

Jaret Wright , acquired on waivers from San Diego on Friday, pitched a scoreless ninth.

Perez retired just one of seven batters in the third inning and was charged with six runs and four hits.

"I'm not disappointed," Perez said through an interpreter. "I was not nervous, I just didn't make the right pitches. My slider was working pretty well, but I got behind too many hitters."

The lefthander walked Rafael Furcal and Giles to start the third before Sheffield's RBI single. After walking Chipper Jones , Perez retired Andruw Jones on a popout. But after back-to-back two-run doubles by Lopez and DeRosa, Pirates manager Lloyd McClendon lifted Perez.

"I'm sure he was a little excited, a little pumped up," McClendon said. "He certainly showed good stuff, but lost the plate."
