SAN DIEGO -- Frustrations reached a boiling point on Sunday for the Padres.

They lost their third consecutive game and are now 4-10 since the All-Star break. Their offense has been missing of late, as they've only plated eight runs in their last four games. They were shut out for the second time this week with a 9-0 loss to the visiting Philadelphia Phillies. To top it off, manager Bud Black and catcher Michael Barrett were ejected in the fifth inning.

"Overall, we got it handed to us by a very good offensive club. [The Phillies are] swinging the bat well," Black said.

The Padres did not play the way their 37,986 fans are accustomed to at PETCO Park. San Diego (53-44) and ace Jake Peavy couldn't handle the Phillies (50-48).

The Padres were down, 4-0, when Barrett was called out on strikes to lead off the fifth inning. Barrett felt the fourth pitch of the at-bat from Phillies starting pitcher J.D. Durbin looked like a ball. Barrett began exchanging words with home-plate umpire Chris Guccione.

Barrett, still upset about the call, tossed his helmet to the ground and threw his bat away, resulting in an ejection. Black jogged out to try and calm Barrett, but Black ended up having his own heated discussion with Guccione, inadvertently bumping him. The result was another ejection, Black's second for the season.

Black, who was already unhappy about a call in the third inning that plated the Phillies' second run, said the bump was "incidental" and did not know how long his suspension would be.

As for Barrett, Black said, "Michael's a competitor. A catcher at times ... [has] a little different perspective other positions don't have. I think he took a little objection to the calls on him based on some of the pitches he was receiving."

Said Barrett: "Things like that aren't supposed to happen, but they did, unfortunately."

The game went even further south for the Padres when the Phillies plated five more runs in the eighth.

Chris Coste's groundout scored Michael Bourn, who led off the inning with a triple. Durbin doubled to right, and Jimmy Rollins drew a walk. With two on and two out, Shane Victorino hit a double off reliever Doug Brocail to drive in two. Brocail was replaced by fellow reliever Royce Ring, who didn't fare much better. Ring walked the next two batters -- Chase Utley and Ryan Howard -- to load the bases before giving up a two-run single to Aaron Rowand.

Black said he was glad Howard -- who homered twice and collected eight RBIs in the four-game series -- was leaving town to face another team.

"Yes, and Rollins and Utley and Victorino," Black said.

The Phillies' offense was but one of the problems facing the Padres. The other was Durbin (2-2), who threw his first career shutout.

Durbin collected his second consecutive victory after being released by three different Major League teams this season, before landing with the Phillies.

"Today was the reason why teams give this guy a [chance] to start big-league games," Black said.

Peavy, meanwhile, was below his usual standards for the third straight start.

"It's just one of those things," Peavy said. "I just want to throw better myself, throw shutouts. I know I'm capable of doing it.

"It's just one of those stretches as a team; we aren't doing a whole lot right. Not pitching well, not hitting, not [playing] the best of defense. I can't worry about what those guys do. I've got to worry about what I control, and that's getting guys out and not giving up runs."

Peavy (9-5) picked up the loss, his third in a row and fourth in his last five starts. He lasted six innings, giving up four runs and nine hits.

Nothing seemed to go right for the Padres, but they hope things will turn around when they hit the road against the Colorado Rockies on Monday.

"I just have faith in our guys that we are going to end up hitting the ball better and scoring more runs at a rate that you are not seeing now," Black said.

Added Barrett: "That's our job now, to put the day behind us and focus on what we have to do to beat the Rockies tomorrow."
