Manny Pacquiao upped the ante yesterday in his standoff with Floyd Mayweather Jr. by filing a lawsuit alleging that Mayweather and others defamed him by falsely accusing Pacquiao of using performance-enhancing drugs.

The suit filed in federal court in Las Vegas further complicates efforts to reach an agreement for a proposed March 13 fight between the two boxers. The fight has been stalled by demands by the Mayweather camp that both fighters submit to random blood and urine tests leading up to the bout.

Pacquiao claimed in the suit that he has never tested positive for any performance-enhancing drugs, but that Mayweather, his father and uncle, Oscar De La Hoya and Golden Boy Promotions chief Richard Schaefer embarked on a campaign to make people think he used drugs.

"The truth did not stop Mayweather and the others," the suit contends. "That is because they are motivated by ill will, spite, malice, revenge and envy."

Pacquiao's attorney, Dan Petrocelli, said his client could be out millions of dollars if boxing fans believe he used steroids or human growth hormone to win titles in seven weight classes.

"The damage to his reputation and lost business opportunities could be in the tens of millions of dollars," Petrocelli said.

AUTOS

JUMP FOR THE RECORD

Travis Pastrana knows a lot of people think he's crazy.

The action sports wild man has a different way of looking at the stunts he's pulled off, most of them on motorcycles but also some as off-the-wall as jumping out of an airplane without a parachute.

"It's a calculated risk," Pastrana said.

His biggest stunt yet will come tonight when he'll try to shatter the world record for the longest jump in a rally car, from the Pine Street Pier in Long Beach, Calif., onto a barge anchored in the harbor, with the Queen Mary in the background.

Pastrana is scheduled to take off at midnight EST (7 p.m. Hawai'i time) live on ESPN.

The current record is 171 feet set by Pastrana's Subaru teammate, Ken Block, in a rally car in November 2006.

SPEEDSKATING

DAVIS GOING DISTANCE

American Shani Davis plans to skate in all five individual distances at the Vancouver Olympics in February and will not compete in the team pursuit.

U.S. Speedskating confirmed yesterday that Chad Hedrick has declined the Olympic spot in the 10,000 and that the spot instead was given to Davis, allowing him to race in the every distance. Davis will not compete in the team pursuit because he did not enter the U.S. pool of athletes by the Dec. 24 deadline.

Earlier this month, Davis said he had no interest in the grueling 10,000 meters and was looking forward to racing in the team pursuit, an event he declined to skate in Turin.

Davis holds the world record in the 1,000 and 1,500 meters and already qualified for those two distances, as well as the 500 and 5,000.
