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 earned 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 62/3 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.

“It’s too bad the other two guys had to wait about a month for me to get there,” he said of the 30-mark.

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.”

Expos 4, Rockies 3

Denver — Tony Batista hit a tiebreaking solo homer in the eighth inning and had three RBIs, and Montreal overcame a scary injury to first baseman Nick Johnson to beat Colorado. Johnson was injured in the third inning when a shot by Royce Clayton took an odd bounce and hit him between his right cheek and jaw. Johnson went down face first to the infield dirt and was kicking his feet up and down as Clayton rounded first for a double. Johnson lay on the field for about 10 minutes before being rolled over, then was strapped to a stretcher and carted off the field about five minutes later. He never lost consciousness and was taken to a hospital for X-rays.

Cubs 9, Astros 2

Houston — Sammy Sosa and Nomar Garciaparra each hit one of Chicago’s season-high six homers, and the Cubs ended Houston’s four-game winning streak.

Mark Grudzielanek homered twice, and Moises Alou and Corey Patterson each had a two-run shot. Sosa’s 567th homer moved him within six of Harmon Killebrew for seventh place on the career list.

It was the 28th homer of the season for Sosa, who also tied Mickey Mantle for 40th place on the career RBI list with 1,509.

Glendon Rusch (6-1) won for the first time since July 15, making a successful return to the rotation after working in relief for the past month. The left-hander allowed two runs and six hits in seven innings. He struck out two and walked two.

Ryan Dempster and Kyle Farnsworth finished with scoreless relief.

The Astros’ return home after a nine-game East Coast road trip couldn’t have gone much worse.

Houston, coming off a three-game sweep of Philadelphia, tied a club record by allowing six home runs. Starting pitcher Pete Munro (2-5) gave up four of them in his worst outing of the season.

Reds 2, D’backs 0

Phoenix — Randy Johnson struck out 14 for the second straight game and became the second pitcher to reach double digits 200 times, yet still wound up with a loss. Cincinnati beat Arizona with an unearned run in the first inning and Barry Larkin’s RBI single in the eighth. Johnson (12-11) trails only Hall of Famer Nolan Ryan (215) in games with 10 or more strikeouts.

Giants 7, Mets 3

San Francisco — Pedro Feliz homered twice, Edgardo Alfonzo also connected and San Francisco beat the Mets to snap a seven-game losing streak against New York. Rookie Noah Lowry had a career-high 10 strikeouts, seven through the first three innings, and Barry Bonds went 3-for-4 with a double to help the Giants maintain a half-game lead in the NL wild-card race.

Feliz hit a home run into the bleachers in left field to start the second inning, then another solo shot in the fifth to give him 17 homers this season. His previous career high was 16, set last season.

Padres 6, Marlins 1

San Diego — Brian Lawrence pitched a five-hitter to match his career high for wins and Ramon Hernandez hit a three-run homer in San Diego’s victory over Florida. NL hits leader Mark Loretta homered and scored three runs in his league-best 54th multihit game. Lawrence (12-10), who finished 12-12 in 2002, struck out four and walked two for just his second win in eight starts. He threw 118 pitches and had 17 groundouts in a game that lasted only 2 hours, 7 minutes.

Phillies 4, Brewers 2

Milwaukee — Jim Thome and Bobby Abreu homered and Eric Milton pitched seven solid innings as Philadelphia ended a seven-game losing streak. Thome’s 37th home run came in the ninth inning off Dave Burba, and gave the Phillies an insurance run. Tim Worrell pitched a perfect ninth for his 14th save.

Milton (13-2), whose .867 winning percentage is best in the majors, is the first Phillies’ pitcher to win 13 of his first 15 decisions since Hall of Famer Steve Carlton in 1980. Milton allowed two runs on five hits, walked three and struck out seven.

Abreu’s 27th homer, a two-run shot off Doug Davis in the sixth, broke a 1-all tie.

It was the first game between the teams this season, and in the reeling Brewers, who have lost 12 of 16, the Phillies found just what they needed after a 1-9 homestand turned up the heat on manager Larry Bowa.

Davis (10-10) didn’t give up a hit until Mike Lieberthal led off the fifth with a triple over the head of center fielder Scott Podsednik. Lou Collier followed with a hard hit off lunging third baseman Wes Helms’ glove that scooted past shortstop Craig Counsell for an RBI single.

Helms then charged in to grab Milton’s pop-up bunt and threw to first to double off Collier and end the inning.

Jimmy Rollins led off the sixth with a single and, one out later, Abreu hit a 415-foot homer to right field for a 3-1 lead. Davis failed for the fourth straight time to tie his career high with 11 wins. He allowed three earned runs on four hits with three walks and seven strikeouts in seven innings.
