All-star 3B Scott Rolen will have surgery on his left shoulder and miss the rest of the season, the Cardinals said yesterday.

"I didn't really have a decision," Rolen said. "I know my body. I know my shoulder."

Rolen, 30, has a torn labrum and was told he will need at least six months to rehabilitate it after surgery. He is expected to return sometime during spring training. Cardinals team medical consultant George Paletta will perform the surgery with assistance from Cincinnati Reds medical supervisor Timothy Kremchek. A date has not been set, but the surgery is expected to be this week. . . .

Cardinals 2B Mark Grudzielanek was hospitalized overnight with a knee infection and will not travel with the team for the start of a four-game series with the Pirates. Grudzielanek's previously injured left knee became worse Saturday when he slid into home during the Cardinals' 4-2 win over the Giants.

The knee swelled and Grudzielanek spent Saturday night at Barnes-Jewish Hospital West. He was discharged yesterday but was not at the game.

Manager Tony La Russa said on his radio program on KMOX that Grudzielanek was expected to be sidelined for at least two to three games.

* PIAZZA OUT: Mets C Mike Piazza was placed on the 15-day disabled list with a hairline fracture of his left hand. Piazza, a 12-time all-star, was injured by a foul tip during an Aug. 16 game against Pittsburgh. The Mets said his assignment to the disabled list would be retroactive to Aug. 17.

* SLOPPY VIZCAINO: The Astros' Jose Vizcaino started at third base for the first time this season and committed two errors in the first four innings. Vizcaino had started eight games at both first and second and seven games at shortstop.
