ST. LOUIS - Scott Rolen gave St. Louis a franchise first, and Chris Carpenter and Jason Isringhausen set career bests.

Rolen became the third St. Louis player to hit 30 homers this season, Carpenter got his 13th win of the season and Isringhausen got his second save of the day as the Cardinals beat the Pittsburgh Pirates 5-3 Friday to complete a day-night doubleheader sweep.

St. Louis won the opener 5-4 behind Dan Haren, who allowed three hits over 6

innings.

Rolen combined with Albert Pujols (37) and Jim Edmonds (31) to give the Cardinals three 30-homer players in one season for the first time.

"It's the best power lineup the Cardinals have ever had," Cardinals manager Tony La Russa said. "I shook all three guys' hands. It's a big day with Scott doing that. With the history the Cardinals have, to have our three guys have their place in that history, that's very significant."

Rolen is one shy of his career high, set with Philadelphia in 1998.

Carpenter (13-5), who won 12 games with Toronto in 1998, matched his season high with nine strikeouts, allowing three runs and seven hits in seven innings. He had missed his previous scheduled start due to tightness in his lower back.

"It sounds strange, but I feel like I'm getting stronger," he said. "My arm feels as good as it has all year. This is what I expected that I could do if I was healthy."

Isringhausen boosted his saves total to 35, one more than he had for Oakland in 2001.

"It was a tough, tough day, but a good day," La Russa said.

St. Louis swept a doubleheader for the first time since Aug. 31, 2002, at Chicago and has won 13 of 17 games overall.

Pittsburgh, which had won nine of 12 coming in, played the sixth of at least seven doubleheaders this year - the most for the team since the Pirates had eight in 1984. The Pirates, 2-3-1 in the doubleheaders, had won their previous four games against the Cardinals.

"A couple of tough losses today," Pirates manager Lloyd McClendon said. "We'll bounce back tomorrow."

Rolen homered in the second inning of the night game, a drive off Nelson Figueroa, who made his first major league start since a 6-2 loss at St. Louis on Aug. 21 last year.

"He threw the ball good," McClendon said. "He kept us in the ballgame and gave us an opportunity to win."

Cardinals reliever Julian Tavarez was ejected from the opener after umpires conducted a lengthy inspection of his dirty, smudged cap before the eighth inning.

Tavarez flipped his hat to a fan in the stands behind the dugout on his way off the field. It's the third time this season that Tavarez' cap has come under scrutiny, with the Braves and Phillies also complaining, but it was the first time he was ejected.

He pitched one-third of an inning in the second game without incident, getting the final out of the eighth inning.
