Texas oilman Nelson Bunker Hunt, who received Eclipse Awards in 1976 and 1985 as thoroughbred racing's outstanding breeder, has decided to sell his breeding and racing stock, it was announced in Lexington, Ky.

"I think it's the hardest decision he's every made because he's so close to his thoroughbreds," said Larry Richardson, general manager of Hunt's Bluegrass Farm.

The first phase of his dispersal will be held at Keeneland on Jan. 9-10. It will include about 285 broodmares, 170 yearlings and 115 2-year-olds. Hunt was North America's leading breeder in 1986 in races won and earnings and is the 1987 leader . . .

Harness racing in California is plagued with fixed races that allow drivers, trainers and others to cash in on the nearly $100 million put down by bettors each year, according to the Los Angeles Herald Examiner.

Most of the cheating involves about 10 of the estimated 160 harness drivers licensed to race in the state, the Herald Examiner reported.

Raymond Seeley, member and former chairman of the California Horse Racing Board, told the newspaper he is aware of attempts by drivers to fix races in the state. "I hate to admit what my thoughts are {about the integrity of the sport}," he said. "We've had way too much of a problem with harness racing in every respect."
