In dire need of starting pitching, the Yankees appear close to acquiring 17-game winner Scott Sanderson from the Oakland Athletics. The clubs apparently have agreed on compensation for Sanderson, and indications are the 34-year-old right-hander is close to agreeing to contractual terms with the Yankees.

Yankees General Manager Gene Michael declined to reveal what the Athletics' compensation would be, but indicated the A's are not asking too much for the right-hander, who has a career 115-100 mark. Oakland's main motivation in the deal is to unload Sanderson's salary. He had been expected to get about $2 million in arbitration after a season in which he went 17-11 with a 3.88 ERA. Even without Sanderson, the Athletics' payroll will exceed $30 million. . . .

Three years after he left baseball to start a second career as an auto dealer, Reggie Jackson is negotiating to sell his sole remaining dealership, Reggie Jackson Volkswagen-Nissan in Palo Alto, Calif., which was forced to close last week when the California Department of Motor Vehicles revoked its sales license.

"As far as we're concerned, they are out of business," said Roddy Rodriguez, the DMV's supervising investigator in San Jose. If the dealership is sold, it would dissolve the last bastion of what Jackson once envisioned as an automobile sales empire. His flagship franchise, Reggie Jackson Chevrolet in Berkeley, abruptly closed its doors in mid-1989, less than a year after Jackson took it over. And his Ford outlet in the mountain town of Quincy shut down in August, unable to make a profit.

The DMV acted when it discovered the secretary of state had suspended the dealership's corporate status in September after Jackson and his partners failed to provide an annual list of officers. In addition, the Palo Alto operation is facing a bill from the state Board of Equalization for what one Jackson associate described as "a lot of money" in back sales taxes. . . .

Four-time National League batting champion Bill Madlock has filed a multimillion-dollar lawsuit against his former agent and attorney, Stephen Greenberg, now the deputy commissioner of baseball. The lawsuit, which also names Madlock's former accountant, Steven Kriegsman, cites breach of contract, breach of good faith and fair dealings, breach of fiduciary duty, fraud and deceit, accounting malpractice, negligence and conspiracy.

Attorney Robert Mintz of San Diego, who filed the suit on behalf of Madlock and his wife, Cynthia, declined to discuss the matter, saying only that the suit, filed in Los Angeles Superior Court, was for "several million dollars."
