Steffi Graf, winner of 22 Grand Slam titles, said it was a "mistake" when she announced she had played her final matches at both Wimbledon and the French Open.

Graf, playing in the TIG Classic, said she may have been too emotional in deciding not to play again in two of tennis's four Grand Slam events. "I made a mistake," Graf was quoted as saying in yesterday's editions of the San Diego Union-Tribune. "That's the way I felt, and that was my immediate response."

Graf, 30, defeated Martina Hingis in an emotional three-set final in Paris. Moments after leaving the court, Graf told NBC Sports that she had played in her last French Open. She then made the same pronouncement about Wimbledon after losing in the final to Lindsay Davenport.

Colleges

Bucked at Ohio State

Three members of Ohio State's acclaimed football recruiting class have been turned away by the school's admissions office because of academic deficiencies and the NCAA has declared three others ineligible. That eliminates a quarter of the 24 recruits who were supposed to report today.

"This is the first time since I've been at Ohio State that I think we've had outright denials by admissions," Athletic Director Andy Geiger said. Geiger has been at Ohio State since April 1994.

The university's admissions office refused the applications of defensive back Ziyier Walker of Fork Union (Va.) Academy, running back Richard Hall of Wyoming, Ohio, and wide receiver Maurice Harris of Jacksonville, Fla.

DuBose Death Questioned

Civil rights activists in San Diego questioned whether the fatal police shooting of former NFL linebacker Demetrius DuBose was racially motivated, saying witness statements indicated the black athlete may have been shot in the back.

Conflicting accounts of the July 24 killing have prompted the family of DuBose, 28, who played for the Tampa Bay Buccaneers, to request an autopsy independent of the police probe and to hire an attorney to conduct a private investigation.

Fittipaldi Out 8 Weeks

Christian Fittipaldi, knocked unconscious in a crash during testing at Gateway International Raceway, remained in a St. Louis hospital and will be sidelined for at least eight weeks. The 28-year-old Brazilian hit the wall in Turn 1 on the Madison, Ill., oval on Monday and was unconscious between five and 10 minutes. Preliminary tests indicated Fittipaldi has a subdural hematoma--a collection of blood--on the left side of his head.

Once the hematoma is stabilized, Fittipaldi is expected to be transported to Miami, where he lives.
