DURHAM, N.C., JULY 16 -- Jeff Blatnick was eliminated from the Greco-Roman wrestling competition today at the U.S. Olympic Festival, but fellow Olympic gold medalists Bruce Baumgartner, Dave Schultz and Mark Schultz won gold medals in the freestyle competition.

Gold medal winners at the festival will represent the United States in the Pan American Games and the world championships.

The third-seeded Blatnick, who returned to serious training in April after missing almost 20 months because of a second bout with Hodgkin's Disease and knee surgery, was beaten by fourth-seeded Morris Johnson, 7-4 and 3-0, in their two matches in the best-of-three format in the 286-pound class. Blatnick won the super heavyweight gold medal at the 1984 Olympics in Los Angeles.

Baumgartner, who won the 220-pound freestyle gold in Los Angeles, has moved up to the 286-pound division and was leading Tom Erikson on points in their first match when Erikson defaulted because of a knee injury.

Mark Schultz won his gold in the 180.5-pound class with a 4-1 decision over Rico Chiapparelli of Baltimore. Chiapparelli graduated this spring from Iowa after winning the NCAA title at 177 pounds.

Dave Schultz had a much tougher time than his brother. Of the 10 winners, Dave Schultz was the only one forced to a third match. Kenny Monday, who wrestled for Oklahoma State, beat Schultz, a former Oklahoma Sooner, 6-2, in the second match. But Schultz came back to take the third match, 10-3.

Greg Gibson, a 34-year-old Marine Corps sergeant stationed in Quantico, Va., came up short in his bid for a gold medal. Bill Scherr -- whose brother, Jim, won at 198 pounds -- defeated Gibson, 13-4.

In the Greco-Roman competition, Mike Mann, a marine who is also stationed at Quantico, advanced in the 149.5-pound division by beating John Giuro of Oak Park, Ill., by forfeit and 6-2.

Brad Anderson of Norfolk, Va., moved ahead in the 198-pound division by beating Tim Catalfo of Kennesaw, Ga., 15-0 (at 5:52) and a pin.

In diving, 1984 Olympic gold medalist Greg Louganis scored four perfect 10s and was awarded 13 9.5s, accumulating 721.38 points, in winning the preliminary competition in the three-meter springboard event.

Louganis' total was just three points short of the festival record he set last year. He looked nearly unbeatable from the outset tonight.

The 10s were awarded for his dives from the sixth through the eighth rounds. He received one in the sixth, two in the seventh and one again for his eighth dive, one of them carrying a 3.3 degree of difficulty. He followed that with his most challenging dive of the evening, a reverse 3 1/2 somersault in tuck position, which has a 3.5 degree of difficulty.

In women's swimming, Annapolis High School freshman Mary Petry, the youngest swimmer in the competition, won her first gold medal on the final evening of competition. She has been touted as one of the new stars of the sport, but until tonight had been swimming in other's wakes, taking a fourth in the 100-meter butterfly and a third in the 200 butterfly.

Tonight, she won the 100 freestyle in a personal-best 57.61, leading from start to finish.

Sarah Anderson added to her festival-record gold medal total tonight by winning the 400 freestyle. She won the 200 freestyle the first night and the 800 freestyle Wednesday. She also was a member of the winning 800 and 400 freestyle relay teams and the 400 medley relay team.
