SAN DIEGO -- Greg Maddux tweaked his back in Tuesday night's start but is still probable to pitch on Sunday, manager Bud Black said.

The right-hander, who is 13-10 with a 3.95 ERA in 32 starts, hurt himself in the third inning. But he completed two more innings and threw off flat ground Thursday.

"(He's) a little sore," Black said. "We're hoping that he's able to make his start. He mentioned that he caught a spike and sort of tweaked his back. … We'll see how he comes in (today). Hopefully the back has quieted down enough to the point where he can make his start."

The 41-year-old began the 2002 season on the disabled list with inflamed nerves in his lower back -- the only DL stint of his 22-year career. And even though he injured himself early in Tuesday's game, Maddux didn't coming out.

"It hurt," Maddux said. "But that's what I do. That's my job (to pitch). I'm going to do everything I can to be ready Sunday. Right now I expect to go out."

Home, sweet home

Thursday's 6-3 home victory -- the Padres' 47th in 78 games -- established a single-season team mark for wins at Petco Park. The 2005 squad posted a 46-35 mark.

Brian Giles thinks the win total has much to do with the Padres being in a win-everyday situation at the right time as well as the willingness of players to buy into the team concept.

"Guys have come to the realization that it's not about our numbers now, it's about winning," Giles said. "We know what this park's all about. … We have to be fundamentally sound and give ourselves more than one or two opportunities a game with a guy at third base so it's not put under a magnifying glass."

Hoffman extends record(s)

Every time Trevor Hoffman closes out a Padres win he's adding to his major league-best save total that stands at 522. But Thursday's save marked the ninth season in which Hoffman has closed out 40 or more games. Mariano Rivera of the New York Yankees has accomplished the feat six times.

"I'm the benefactor of a lot of good guys around me," Hoffman said.

Wade to Astros GM

The Padres are unofficially down to five general managers after the Houston Astros named Ed Wade as general manager.

Wade -- the general manager in Philadelphia from 1998-2005 -- spent the past two seasons as a professional scout for the Padres. Wade's departure leaves the Padres with Kevin Towers and former GMs Sandy Alderson, Randy Smith, Ted Simmons and Paul DePodesta.

Smashing celebration

Home run-hero Scott Hairston and rookie Kevin Kouzmanoff celebrated Wednesday night's 5-3 win by hanging out with the rock band Smashing Pumpkins. While the two attempted to race out of the clubhouse as quickly as possible, they didn't catch any of the group's show at San Diego State's Open Air Theatre. They did, however, get to hang out with Kouzmanoff's "hero", lead singer Billy Corgan and drummer Jimmy Chamberlin aboard the tour bus.

"I'll always remember that," Hairston said.

Et cetera

Prior to Thursday's game Jake Peavy was honored as the Padres' recipient of the 2007 Roberto Clemente Award for his outstanding play and charitable work in the community. Peavy is also up for the MLB award which will be announced before Game 3 of the 2007 World Series. … 3B Kevin Kouzmanoff has reached base safely in 14 straight games and has hit safely in 22 of his past 27. Over that period he's raised his average from .233 to .270. … Pittsburgh's Nyjer Morgan tripled to leadoff Thursday's game and became the first Pirate since Omar Moreno on April 30 and May 1 of 1980 to lead off back-to-back games with a triple. Tampa Bay's Elijah Dukes also accomplished the feat on May 20 and 22 this season. … Adrian Gonzalez's second-inning double was his 71st extra-base hit of the year, tying him with Dave Winfield for fifth on the single-season list. Steve Finley had 84 extra-base hits in 1996.
