PHILADELPHIA (AP) _ After nine knee operations, Darren Daulton has decided to end his baseball career.

Dalton announced his decision in Philadelphia, where he played all but a few months of his major-league career. The Phillies said Daulton will join the staff of Time Cards Inc. of Las Vegas to help promote youth sports.

The 35-year-old Daulton became a free agent just five days after helping the Florida Marlins defeat the Cleveland Indians in the 1997 World Series. The team declined to exercise their $5 million option.

Daulton, primarily a catcher, also played first base in the latter stages of his career. He was traded to the Marlins for outfielder Billy McMillon last July.

A mainstay of the team that won the NL pennant in 1993, he spent most of 1996 at home with bad knees and acknowledged he might never play again. But he reported to spring training last year and went on to compile impressive statistics with Philadelphia until the trade.

In the 1997 World Series, Daulton provided the leadership that helped the Marlins win the title.
