The Florida Marlins' new ballpark won't open until the 2012 season, a one-year delay because a recent court challenge slowed the start of construction.

Last Friday, a Miami-Dade circuit judge eliminated the final legal obstacle -- a lawsuit filed by auto dealer Norman Braman against several projects, including the 37,000-seat, retractable-roof stadium. The Marlins, however, have yet to break ground at the site.

"The litigation pushed us back," team president David Samson said. "We met with the construction manager, and he told us the risk was not manageable to open in 2011. The cost of accelerating construction would be too high."

The Marlins still expect to meet the targeted cost of $515 million for the ballpark, Samson said. The franchise is responsible for overruns.

Phillies second baseman Chase Utley has had arthroscopic hip surgery and is expected to need four to six months to recover. The three-time All-Star had surgery Monday to trim the labrum and a bony lesion in his right hip at the Hospital for Special Surgery in New York.

• Roger Clemens' former trainer gave samples of his DNA to federal investigators trying to ascertain whether the star pitcher committed perjury before Congress, two New York newspapers reported. The request for a DNA sample from trainer Brian McNamee suggests that investigators found readable DNA on the syringes, needles and gauze pads McNamee turned over to federal prosecutors in January, The New York Times and Daily News reported Monday.
