SAN DIEGO -- The San Diego Padres finally had a high-scoring game at Petco Park.
Xavier Nady had four hits and a career-high four RBI to lead the Padres to an 11-3 victory over the Pittsburgh Pirates on Saturday night.
The Padres struggled offensively last year in their first season at their new ballpark. San Diego averaged 5.4 runs on the road, but just 4.1 at home. They totaled only three runs in their first two games at Petco Park this season.
"It's good for the club to be swinging the bats like that," Padres manager Bruce Bochy said. "We got a huge day from Nady. He has been swinging the bat well."
After a poor performance in his first start, Woody Williams (1-0) limited the Pirates to three runs and five hits with six strikeouts in six innings.
"Williams put his fastball in a good spot," Pittsburgh's Matt Lawton said. "He threw his offspeed stuff for strikes."
Nady had a three-run homer, a triple and two singles for his first career four-hit game.
"I hit it well, but you never know in this ballpark," Nady said of his home run.
Lawton had two hits and three RBI to lead the Pirates.
San Diego trailed 3-2 before taking the lead for good on Phil Nevin's three-run homer in the fifth inning. Mark Loretta, who had three hits, and Brian Giles walked to open the inning before Nevin hit a 403-foot shot to center field off Pirates starter Oliver Perez (0-2).
"We got a big blow from Nevin, he crushed it," Bochy said.
Nady hit a run-scoring triple and scored on a sacrifice fly in the seventh, and added his homer in the eighth. Loretta reached base five times -- including two walks, two singles and a triple.
"We know we can score runs here, we just have to execute," Loretta said.
Perez, who has an 11.00 ERA after two starts, walked five and struck out four in four-plus innings.
"Right now, Oliver is just not sharp," Pirates manager Lloyd McClendon said. "When you pitch behind like he did, it's going to hurt you."
The Pirates got a run in the third on an RBI double by Lawton. San Diego tied the score in the bottom of the inning on Brian Giles' double-play grounder, and took the lead in the fourth on Williams' RBI single.
"The hitting part is lucky. The reason I am here is to pitch and I still have got to make better pitches," Williams said. "I was fortunate. I threw a lot of pitches that were hittable that they took."
Lawton came through for the Pirates again in the fifth, with a two-run single to score Freddy Sanchez and Benito Santiago for the Pirates' last lead.
"Matt came up big," McClendon said. "When you have two-out RBI like he did twice tonight, you expect to win."
Pirates center fielder Jason Bay had a throwing error in the fourth inning, the first by the Pirates in the last 37 innings. ... Loretta also stole his first base of the season. He received the Silver Slugger award before the game for the top batting average in the National League for second basemen in 2004.
