Rockies Manager Jim Leyland ended speculation about his managerial future last night and confirmed that he was retiring from managing at the end of the season.

"I'm not going to talk about this every day for the rest of the season," Leyland told the Denver Post following the Rockies' 4-1 loss to the Expos. "I'm retiring as manager, and that's it."

Leyland, who managed the Marlins to a World Series title in 1997, joined the Rockies in the offseason after managing the Marlins for two years. He had said earlier he was 99 percent sure he was retiring after this season, his 15th as a major league manager.

He addressed his players prior to the Rockies' 5-3 win over the Expos Monday to advise them of his decision.

Meantime, Former Indians assistant general manager Dan O'Dowd will interview for the Rockies' vacant GM job later this week, the team said. The Rockies are seeking a replacement for Bob Gebhard, who resigned Aug. 20.

FISHING FOR NEW SITE: Marlins owner John Henry says downtown sites in Miami and Fort Lauderdale have emerged as the front-runners for a new ballpark. The sites are among six being considered by the Marlins in Dade and Broward counties. The team will settle on two finalists by December, then begin discussions with public officials about financing.

Henry said he'll choose the site where the most public money is available. He hopes to build a 42,000-seat ballpark with a retractable roof, using taxpayer money to finance 75 percent of the estimated $400 million cost.
