PHILADELPHIA -- With one trade done and another reportedly brewing, the Padres went down quietly to their sixth consecutive loss on Saturday, absorbing a 2-0 shutout at the hands of rookie Robinson Tejeda and three Phillies relievers before 33,992 at Citizens Bank Park.

It was the 10th time the Padres, now only two games above .500, have been blanked.

Joe Randa, acquired from Cincinnati for a pair of Minor League pitchers to play third base and provide right-handed punch, is expected to arrive Sunday, but Padres manager Bruce Bochy doesn't expect him to make it in time to start the series finale.

In another proposed swap, Phil Nevin could go to the Orioles in exchange for pitcher Sidney Ponson if Nevin waives his no-trade clause.

"I haven't talked to anybody about that," Nevin said, having produced one of the Padres' four hits. "It's not solely my decision. If something like that happened, there'd obviously be a lot of things to think about."

Despite Tejeda's struggles with the strike zone -- he walked five men in six innings -- the Padres could generate nothing substantial offensively. Their biggest threat came in the seventh against reliever Ryan Madson when Ramon Hernandez doubled leading off and took third on pinch-hitter Mark Sweeney's one-out single. But Dave Roberts banged into a double play to end the threat.

Pedro Astacio gave the Padres six effective innings, allowing six hits and three walks. Chase Utley, who decided Friday night's game in the 11th inning with a two-run homer, hammered a solo shot to the same location in right center in the fourth. In the sixth, Utley singled when Astacio couldn't locate first base on Nevin's toss, moved to third on Bobby Abreu's single and scored on Ryan Howard's sacrifice fly.

"I felt good on the mound," said Astacio of his second start with the Padres, "but you never feel good when you lose."

The Padres had leadoff walks in the first and second innings and couldn't cash in. They couldn't deliver Brian Giles from scoring position in the sixth after a walk and wild pitch. Their inability to come through in pressure situations has dogged them throughout this 0-5 trip through the East.

Lefty Craig Breslow, recalled from Double-A Mobile, struck out three in 1 2/3 innings in his Major League debut, allowing one hit and a walk.

Breslow was on his way back to Double-A to make room for Randa, but he had a lot of memories to take back to his BayBears teammates. Padres general manager Kevin Towers, who gave the word to Breslow that he was going to Philadelphia on Friday night in Jackson, Miss., spent Saturday completing the Randa swap.

"You get a sense being around a club that you need to do something," Towers said, withholding comment on the Nevin-Ponson rumored deal. "I felt the last three or four days, we really need to do something. We recognized a deficiency and we needed to address it.

"It's twofold. It sends a message to our fans, and we're going to continue to be aggressive and hopefully spark this club."

Since forging a commanding lead in the National League East with a 24-6 run, the Padres have gone 17-29 since June 1. Adam Eaton has been sorely missed in the starting rotation since June 15 with his injured right middle finger, and the bullpen has taken a few hits lately with Rudy Seanez and Chris Hammond unavailable.

Like Clay Hensley, who has pitched four hitless innings of relief since being recalled from Triple-A Portland, Breslow arrived and provided relief for the bullpen with his strong showing.

"I'm glad I had a chance and things went pretty well," said Breslow, a Yale graduate in biochemistry who was released by the Brewers organization July 4, 2004, and signed with the Padres in February for $1, Towers said, after an impressive tryout in Arizona during Spring Training.

"Today made it all worth it," said Breslow, whose name is forever entered in the Baseball Encyclopedia. "I came and hopefully proved to the guys up here -- and myself -- I can succeed."

He left Mississippi at 4:30 a.m., caught a connection in Atlanta and came straight to Citizens Bank Park from the airport. The Padres gave Breslow the satisfaction of one night in a big league hotel room before he would be returning to the less stately quarters of Double-A ball.

"I've still never seen the guy pitch," said Towers. "It's a pretty cool story."
