EUGENE, Ore. (AP) – Marion Jones turns her attention from clearing her name to beating the competition Saturday at the star-studded Prefontaine Classic.

The meet also features Jones’ embattled boyfriend Tim Montgomery against Maurice Greene in the 100 meters.

Jones will compete in the long jump and in the 100 meters. Her sprint foes include Gail Devers in her first 100-meter race of the season.

On Wednesday, Jones held a news conference in San Francisco to call for a public hearing of the case the U.S. Anti-Doping Agency may or may not bring against her.

Her lawyer said Thursday she has passed a lie detector test in which she denied ever using illegal performance-enhancing drugs.

Jones and Montgomery didn’t attend Friday’s pre-meet news conference. Jones sent word that she would meet with reporters after Saturday’s competition.

Greene – three-time world champion and reigning Olympic gold medalist in the 100 – was on hand, however, expressing sympathy for Jones but declaring that Montgomery’s world record in the 100 meters could be forever tainted.

“Marion’s situation is tough,” Greene said. “I feel sorry for her actually, but I can’t concern myself with it.”

USADA is using evidence and documents gathered in the criminal investigation of the Bay Area Laboratory Co-Operative to pursue athletes who have been incriminated even though they have not tested positive. Jones and Montgomery were among those who gave testimony to the grand jury probing the BALCO case.

Greene said that the USADA needs to make a decision on whether to proceed against Jones or anyone else.

“Do something and get it over with,” Greene said, “so we can get on with what we have to do, so our sport came move on from this.”

The anti-doping agency already has notified Montgomery and three other track athletes that it has evidence that could lead to their being banned from the Athens Olympics.

Greene said that Jones is in a difficult situation because she is insisting she has not taken any prohibited substances while the USADA is “telling her that they’ve got something on her.”

Returning from two injury-plagued seasons, Greene has the second-fastest wind-legal time in the world this year at 10.02 seconds and has run a wind-aided 9.78. Greene said it’s only a matter of time before he regains the world record of 9.78 set by Montgomery two years ago in Paris.

The legitimacy of that record, Greene indicated, is in doubt.

If Montgomery is suspended, Greene said, “it’s going to taint everything he’s done.”

The BALCO probe has overshadowed performances on the track leading up to the U.S. Olympic trials July 9-18 in Sacramento.

The Prefontaine meet, sponsored by Nike, features a “who’s who” of top Americans, along several outstanding international athletes.

In addition to Greene and Montgomery, the 100 features world 200-meter champion John Capel, Justin Gatlin, Mickey Grimes and Shawn Crawford.

The women’s 100 includes Jones, Devers, Inger Miller, Torri Edwards and Chryste Gaines. Gaines is among the four told by USADA that they could face a two-year ban.

Also in the meet:

• Alan Webb, former high school sensation who has emerged this season with the world’s fastest 1,500 meters (3:32.73), will run the Prefontaine mile and is a threat to break 3 minutes, 50 seconds.

• Four-time world champion and 1996 Olympic gold medalist Allen Johnson will be the overwhelming favorite in the 110-meter hurdles.

• Toby Stevenson, who this year became the second American to clear six meters (19 feet, 8 inches), goes against American record holder Jeff Hartwig in the pole vault. The field also includes 2000 Olympic champion Nick Hysong, 2001 world champion Dmitiri Markov of Australia and, competing on his home track, Oregon freshman Tommy Skipper, who last week won the NCAA title.

• World indoor champion Christian Cantwell, who has the top throw outdoors in the shot put this season at 73-11, faces 2000 Olympic silver medalist Adam Nelson.

• Maria Mutola of Mozambique, Olympic gold medalist and multiple world champion indoors and outdoors at 800 meters, competes in her 13th Prefontaine Classic.

• Two-time world champion Felix Sanchez of the Dominican Republic goes against reigning Olympic champion Angelo Taylor in the 400 hurdles. Sanchez was undefeated in the event last year.
