SAN DIEGO — Greg Maddux has been around so long that even an average outing can produce a major league record.

Maddux slogged through five innings — issuing his first walk in 10 starts — and the San Diego Padres beat the Pittsburgh Pirates 5-3 on Tuesday night, the fifth straight victory for the NL wild-card leaders.

Butler native Khalil Greene had three hits, reached base five times and drove in two runs for the Padres, who remained 1½ games in front of Philadelphia in the wild-card race. The Phillies beat St. Louis 7-4 in 14 innings.

The Padres also stayed a game behind first-place Arizona in the NL West after the Diamondbacks beat San Francisco 5-0.

Maddux (13-10) won for the sixth time in seven decisions and for the 346th time in his career. The Padres have won eight of his last 10 starts.

"It was a good team win," Maddux said.

The 41-year-old right-hander also reached 13 wins for the 20th consecutive season, passing Cy Young for the major league record.

It wasn't his prettiest start, though. Maddux fell behind 2-0 in the first inning and ended up allowing three runs and seven hits. He struck out two and walked two.

Maddux's streak of not walking a batter ended at 59X\c innings when he walked Jason Bay on a full-count pitch to load the bases with two outs in the third and the Padres leading 4-2. Maddux then got Ronny Paulino to fly out to end the inning.

Maddux hadn't walked a batter since July 28 at Houston, when he issued ball four to pitcher Roy Oswalt in the second inning. Maddux went through his next nine starts without walking a batter, and his overall string reached 244 batters.

Maddux wasn't disappointed the streak ended.

"You pitch to win games. You beat lineups, you don't beat hitters," he said. "You don't want to give in to keep from walking somebody. You want to try to keep making the best pitch you can. I've always thought I'm trying to get the hitter out, not trying not to walk him. Walks are going to happen. I didn't want to walk the guy I walked, but it happened, and I'm just glad they didn't score."

The streak was the second-longest of Maddux's career. In 2001, he set the NL record at 72Z\c innings.

"The guy is still amazing," Pittsburgh's Freddy Sanchez said. "You could tell that this wasn't his sharpest game, but he still makes you battle every at-bat for everything you get. We got to him some but he makes you earn it."

Ex-Padre Xavier Nady had three hits off Maddux, including a solo homer into the second deck in left field with two outs in the fifth to pull the Pirates to 4-3.

Trevor Hoffman pitched the ninth for his 39th save in 44 chances, extending his career record to 521.

Pirates lefty Tom Gorzelanny (14-8) also went five innings, allowing four runs and nine hits, striking out four and walking four. It was just the fifth time in 30 starts he didn't pitch longer than five innings.

"I didn't feel good from the beginning," Gorzelanny said. "I was walking guys and that's the big thing."
