Philadelphia ? Scott Rolen should be much happier in his new red uniform.

The slugging third baseman was traded to the St. Louis Cardinals in a five-player deal on Monday, ending a seven-year tenure with the Philadelphia Phillies that ended miserably.

The Phillies get third baseman Placido Polanco, pitcher Bud Smith and reliever Mike Timlin for the three-time Gold Glove winner, minor league pitcher Doug Nickle and cash.

“We are very pleased and excited to add Scott Rolen to our lineup,” Cardinals general manager Walt Jocketty said in a statement. “He is an All-Star, a proven run producer and an excellent defensive player.”

Rolen, 27, is expected to join the Cardinals for tonight’s game at Florida. He becomes part of a powerful lineup that already features Jim Edmonds, Albert Pujols and J.D. Drew.

Rolen, who made his first All-Star team this season, is batting .259 with 17 homers and 66 RBIs. He goes from the last-place Phillies to the first-place Cardinals, who lead the NL Central by five games over Cincinnati.

Rolen had been the subject of trade rumors since rejecting a 10-year contract extension last November that could’ve been worth up to $140 million. He signed an $8.6 million, one-year deal in January, but made it clear he wanted to become a free agent after this season. That decision forced the Phillies to make a move or risk losing him for only a pair of picks in next June’s amateur draft.

Polanco, 26, is hitting .284 with five homers and 27 RBIs. He batted .307 last season and .316 in his first full year, in 2000.

Smith, who pitched a no-hitter in his rookie season last year, was sent to Triple-A Memphis on July 20 after going 1-5 with a 6.94 ERA in 11 appearances, including 10 starts.

Timlin is 1-3 with a 2.51 ERA in 42 appearances and is holding righties to a .197 average.

Nickle, 27, was 3-5 with a 2.97 ERA and seven saves in 34 games one of them a start at Scranton this season.
