PHILADELPHIA -- Phillies fans sold out Citizens Bank Park again Saturday, with the 45,050 wanting to be there for a milestone but probably not sure how they'd react if it was reached.

It won't be reached if the Phillies' offense continues at this pace.

Philadelphia kept everyone waiting for loss No. 10,000 for a second consecutive game, beating St. Louis, 10-4, to improve to 1,189 games under .500 as a franchise.

More importantly, the Phillies are on the verge of sweeping the Cardinals to kick off the second half of the season, and they are getting plenty of offense doing so.

"If we're scoring 10 runs a night, it's going to be tough for teams," said Pat Burrell, who went 3-for-3 with four RBIs and a walk. "The reality is, that's not going to happen."

It sure seems possible after the show put on the past two games.

The Phillies scored in five of the first six innings Saturday and reached double-digit hits for the sixth time in seven games.

Jimmy Rollins, Ryan Howard and Aaron Rowand each homered for the Phillies, who moved two games over .500.

Rollins finished with three hits and bagged his National League-leading 37th multihit game of the season. The leadoff shot was his fifth of the season and broke the previous record of four held by him and two others.

Rowand's solo shot in the third inning was one of his four extra-base hits during the game. He continued to beat up Cardinals pitcher Mike Maroth, improving to 12-for-20 during his career against him.

"I knew he was pretty good lifetime against me," said Maroth, who allowed six runs over five innings. "He did it again today."

Phillies starter Cole Hamels labored to 110 pitches after six innings. He allowed four runs, but got plenty of support to carry his 11th win this season.

The Phillies' offense tallied for 23 runs and 37 hits -- including five home runs -- over the past two games.

Every starter but Hamels and Carlos Ruiz hit safely. Hamels reached on a fielder's choice and came around to score.

"In this ballpark, with the lineup we have, there's a reason we should and are leading in runs produced," the left-hander said. "Our team has all sorts of power, and we're able to hit in the clutch right now."

No one was more clutch Saturday than Burrell. The Phillies left fielder is 9-for-15 over his last five games, with nine RBIs.

His average jumped 10 points after Saturday's game, to .227, his highest since June 7.

"He's swinging the bat a lot better," manager Charlie Manuel said. "He's staying on the ball longer."

"Whenever you're hitting the ball good, they drop in," Burrell said. "That's huge for me, and that's what I'm here for, to drive in runs."

Hamels was appreciative.

The 24-year-old said he was a little thrown off by his All-Star schedule earlier in the week and struggled somewhat with his command.

But, like Kyle Kendrick the day before, Hamels managed to avoid the distinction of being the losing pitcher on record for No. 10,000.

"The team definitely helped me out," Hamels said. "I think I was more or less giving it away to the other team. The team kept battling back and scoring a lot of runs for me. It definitely makes my job a lot easier."

It was good enough to begin a winning streak to start the second half of the season.

Hamels' All-Star teammate, Rowand, finished with three doubles and a home run. Manuel said he's seen an entirely different player than the one who struggled during Spring Training.

"Rowand works, man," Manuel said. "In Spring Training, he had a terrible spring and people were writing him off. I've always stood by him, because I know how hard he works and he's a grinder. He'll stay there and he works on hitting the ball."

Like Burrell, though, Rowand admitted the team's postseason hopes couldn't ride on putting up crooked numbers every game and that consistent efforts from their pitching staff will be needed.

Hamels' ERA rose to 3.83 following Saturday's outing, giving Kendrick, with a 3.82 ERA, the lowest number among Phillies starters.

The Phillies' staff ERA has been around the bottom of the National League all season.

"Our offense has been good all year," Manuel said. "As you can see, it's been pretty consistent -- as far as scoring runs. At the same time, there's an old saying: You got to win the best way you can. If you score runs, that's how you got to learn how to win, I guess."
